A-1. Base material layer The thickness of the above base material layer may be any appropriate thickness depending on the application. The thickness of the substrate layer is preferably ΙΟμηι 150150 μm, more preferably 2〇μηι~ΙΟΟμιη. 099120779 7 201114594 In the case where the haze value of the laminated film of the present invention is from 13.5% to 80%, the haze value of the base material layer may be any appropriate value. The substrate layer preferably has a haze value of from 1% to 8% by weight, more preferably from 1% to 6% by weight. If the haze value of the base material layer is such a range, it is possible to obtain a laminate film having the outer layer of (4) and the outer layer. The base material layer contains a thermoplastic resin. As the thermoplastic resin, any thermoplastic resin which can be used as long as it can be formed by melt extrusion can be used. Examples of the thermoplastic resin include a polyolefin resin such as a propylene polymer, a polyethylene, and an olefin thermoplastic elastomer (Tp〇), and a modified product thereof; an alpha olefin and a compound of the B (for example, ethyl acetate vinegar) a copolymer of (meth)acrylic acid vinegar; polyamine; polyester; polycarbonate; polyaminocarbamic acid polyvinyl chloride; As the propylene-based polymer, for example, a propylene homopolymer, a block polypropylene, a random polyacryl or the like can be exemplified. When a propylene fluorene homopolymer is used as the above thermoplastic resin, the structure of the propylene homopolymer can be either the same row, the miscellaneous row, or the opposite row. When polyethylene is used as the above thermoplastic resin, the polyethylene may be any of low density polyethylene, medium density polyethylene, and high density polyethylene. In the base material layer, the thermoplastic resin may be used singly or in combination of two or more. The form includes doping and copolymerization. Commercially available products can be used as the thermoplastic resin. As a specific example of the hot-selling product of the commercially available product, the "PF380A" (block polypropylene) manufactured by Sun Allomer Co., Ltd., and the like can be mentioned. 099120779 201114594 The above substrate layer may contain any appropriate additive as needed. The additive which may be contained in the beauty layer may, for example, be an ultraviolet absorber, a heat resistance agent, a filler, a lubricant or the like. The type, number, and amount of the additives contained in the base material layer can be appropriately set depending on the purpose.

Surface layer The thickness of the above surface layer is preferably 2 μηι to 1 μμη1, more preferably 2 μηι to 8 μιη, and particularly preferably 2 μm to 5 μm. When the thickness of the surface layer is less than 2 μm, it is difficult to obtain a desired surface roughness by 099120779 9 201114594, and it may be difficult to obtain a laminated film having a high haze value. When the thickness of the surface layer is larger than ΙΟμιη, the mechanical properties of the surface layer affect the mechanical properties of the laminated film as a whole, and the workability of the laminated film may be deteriorated. The haze value of the surface layer of the present invention may be raised to any appropriate value before the haze value of the laminated film of the present invention is raised from 135 to 8%. It is preferably 13·5% to 80%, more preferably 15% to 80%, still more preferably 20% to 80%, particularly preferably 30% to 80%, and most preferably 35°/. ~75%. When the haze value of the surface layer is within such a range, a laminated film having an appearance suitable for the appearance adjustment use can be obtained. The haze value can be measured by the method specified in JIS Κ 7136 (2000). The arithmetic mean surface roughness Ra of the surface layer is 〇_5μηι 〜2. 〇μιη, preferably 〇8μιη 〜1.9μιη, and the arithmetic mean surface roughness Ra of the surface layer of the ι.Ομη^9μιηβ is in this range. Inside, a laminated crucible having an appearance suitable for the appearance adjustment use can be obtained. The above surface layer may contain any appropriate resin within the range in which the effects of the present invention can be exhibited. The following three embodiments are preferred. (Complex Form 1) The surface layer contains an embodiment of polyethylene and an ethylene-vinyl acetate copolymer. (Embodiment 2) The surface layer contains an embodiment of a polyethylene and a propylene polymer. (Embodiment 3) The embodiment in which the surface layer contains a propylene-based polymer and an olefin-based thermoplastic elastomer. 099120779 10 201114594 First, the case of the above (Embodiment 1) is performed. In the above (Embodiment 1), the surface layer contains a polyethylene and a vinyl acetate copolymer. The weight ratio of the above polyethylene to the ethyl acetoacetate copolymer may be any weight ratio depending on the desired haze value and/or surface weight. The weight ratio (polyethylene: B to drink acid and ethylene binder) - preferably 20: 80 to 80: 20, more preferably 3 〇: 7 〇, : 20, especially good 3 〇: 7 〇 ~ 7 〇 3〇. Preferably, the above-mentioned polyethylenes and the above-mentioned ethylene-acetate copolymers exhibit different melt flow rates. If the polyethylene and the ethylene and ethylene acetate oxime polymers exhibit different melting flow rates, the surface layer forming material is stretched in a hot state, and the resin having a high melt flow rate is easily elongated. Since the resin having a low melt flow rate is not easily elongated, it is possible to obtain a surface layer of an island structure having a sea portion formed of a resin having a high flow rate of smelting and an island portion formed of a resin having a low flow rate. As a result, the haze value and the surface thick chain enthalpy can be expressed on the surface layer by the unevenness due to the island structure. The above-mentioned polyethylene has a better flow rate of sacrificial flow / 10 minutes ~ (10) state minutes 'more preferably 9g / 10 minutes ~ 8 〇 g / 1 () minutes, especially good 9_ minutes ~ melt flow rate can be obtained by knife The best 10g / l 〇 minutes ~ 5 〇 g / 1 〇 minutes. When the flow rate of the polythene solution is less than 8g/lGmin, the difference in the melt flow rate between the polyethylene and the above ethylene-ethylene vinegar copolymer becomes smaller, and the haze value and surface fineness become overJ. Then, when the melt flow rate of the t-wife is greater than (10) minutes, the haze value and the surface roughness may become excessive. 099120779 11 201114594 The method specified in JISK7210 is measured. The melt flow rate of the above ethylene-vinyl acetate copolymer is preferably from 0.1 g/10 min to 7 g/l min, more preferably from 2 g / 1 min to 5 g / 1 min, particularly preferably 0.2 g / l G min ~ 3g/lG minutes, most (four) 4g/1Q minutes ~ 2 (four) 〇 minutes. The ethylene-vinyl acetate S copolymer is less than 〇 ι 咖 minutes, and the haze value and the table (4) roughness may become too large. When the county-state flow rate of ethylene-acetate copolymer is greater than 7g/1G minutes, the polyethylene

The difference in the melt flow rate of the ethylene-vinyl acetate copolymer becomes small, and the value and surface roughness become too small. In the above range, a surface layer of an island structure having a sea portion formed of polyethylene and an island portion formed of a vinyl acetate S copolymer can be obtained. The haze and surface reduction of the laminated film can be controlled by adjusting the difference between the melt flow rate of the above polyethylene and the (iv) flow rate of the above-mentioned ethyl acetate vinegar copolymer. That is to say, when the difference between the flow rate of the glaze and the melt is large, the difference between the easy-to-extension of the surface acoustic shape and the material is large, and the surface layer of the island structure can be obtained, so that the haze value and the surface roughness can be obtained. On the other hand, when the filament of the flow rate is small, the difference in the elongation of the surface layer forming material is small, and it is difficult to obtain a surface layer having a clear island structure, so that the haze value and the surface domain degree can be obtained. Laminated film. When the viscosity difference between the low-viscosity resin and the high-viscosity resin is small, it is difficult to obtain a clear suppression. 099120779 12 201114594 2 Low haze and surface coarse sugar flatness) on the other hand 'in low viscosity resin (showing high melt flow rate. Viscosity resin (showing low melt flow rate) viscosity difference can get a clear deformation flow difference, island The structure is clear, and a laminated film with high haze and a rough surface (four degrees) can be obtained. The target haze and surface roughness can be controlled by the difference in viscosity of the resin used. In addition, in order to obtain high haze and surface roughness The degree is difficult to be the melting point of the high-viscosity resin belonging to the island structure, and the bright point of the low-viscosity resin in the sea structure. The reason is that, when the elongation is as long, the island first cools and solidifies, and the sea forms a resin material when the fat is solid. It is not cooled and solidified, thus forming a clear island structure. The above surface layer preferably has a smelting temperature Tm of two or more points in the differential scanning calorimetry (dsc). The (four) different polyethylene and ethylene-acetic acid ethylene vinegar copolymer can be obtained. By using polyethylene with different melting point and ethyl acetate-ethylene acetate copolymer in the surface layer, the hue difference adjustment can be utilized. The haze value of the laminated film and the roughness of the surface. More specifically, in the 臈成科, the age of the money is cooled and solidified, the high-characterized polyethylene is first solidified, and then the low-brightness ethylene-ethylene acetate vinegar copolymerization The material solidifies, so when 'the melting point difference is large', a clear island structure can be obtained in the above surface layer, and the money value and the surface _ degree are larger _ layer film can be obtained. It is difficult to obtain a surface layer having a clear island structure, so that a laminated film having a small haze value and a small surface roughness can be obtained. Further, the above-mentioned melting temperature of the melon can be determined by the method of JISK712i: 099120779 13 201114594 In the present specification, "having a melting temperature Tm of two or more points" means that two or more radiance endothermic peaks are generated in the DSC curve. The melting point of the polyethylene is preferably from 100 ° C to 1253⁄4, more preferably 1 〇 5. 〇~125X:, then Preferably, ll ° ° C ~ 125 ° C, particularly preferably 115 ° C ~ 120 ° C. The melting point of the ethylene - vinyl acetate copolymer is preferably 5 ° ° c ~ 12 (rc, more preferably 60 ° C ~ 120 ° C Further preferably 70 ° C ~ 120 ° C, especially good 80 χ: ~ 115 Χ:, the best 100 ° C ~ 115 ° C. The melting point of the above polyethylene and the above ethylene - vinyl acetate copolymer melting point difference Preferably, it is 5°c~65. 〇More preferably l(TC~6(rc, especially good 15〇c~5〇〇c.) The difference between the melting point of polyethylene and the melting point of ethylene-vinyl acetate copolymer is here. Within the above range, the laminated film of the present invention, that is, a laminated film having an arithmetic mean surface roughness Ra of 0.5 μm to 2.0 mm and a haze Z of 13.5% to 80% can be easily obtained. The laminated haze value and the surface (four) degree phase of the present invention are adjusted by the compatibility of the above polyethylene and the ethylene-vinyl acetate 0| copolymer in the above surface layer. When the phase difference between the polyethylene and the ethylene-vinyl acetate is low, a clear sea-island structure can be obtained in the surface layer, and thus a laminated film having a large haze value and a large surface roughness can be obtained. On the other hand, when the compatibility is high, it is difficult to obtain the structure of the open-hand island, and therefore, it is possible to (4) a laminated film having a small money value and a small surface roughness. The compatibility can be adjusted, for example, by the ratio of the content of the cultivating county (four) from the ethyl acetonitrile copolymer. The content ratio of the composition of the vinyl acetate from the vinyl acetate to the monomer 099120779 201114594 is preferably 10% by weight or more, more preferably 15% by weight or more, and particularly preferably 20% by weight or more, preferably 2〇. Weight%~3〇% by weight. When the content ratio of the constituent unit derived from vinyl acetate is within such a range, the ethylene-vinyl acetate copolymer exhibits appropriate compatibility with the polyethylene, and the laminated film of the present invention can be easily obtained, that is, it has arithmetic The average surface roughness of 1^ is 0.5卩111~2. (The surface layer of ^111 and the laminated film having a haze value of 13.5% to 80%. The above polyethylene and ethylene-vinyl acetate copolymer can be used commercially. Specific examples of the polyethylene which is commercially available are, for example, the product name "Petrothene 209" manufactured by Tosoh Corporation, the product name "NOVATEC LD LJ803" manufactured by Nippon Polyethylene Co., Ltd., "NOVATEC LD LC701", and " For example, "EVAFLEXEV 270" manufactured by Mitsui DU PONT POLYCHEMICALS Co., Ltd., etc., may be used as a specific example of the ethylene-vinyl acetate copolymer which is commercially available. The surface layer may contain any appropriate additives as needed. As the additive which can be contained in the surface layer, for example, an additive described in the item A-1 can be used. Next, the case of the above (Embodiment 2) will be described. In the second embodiment, the surface layer contains polyethylene and a propylene-based polymer. Any propylene-based polymer may be used as the propylene-based polymer. Specific examples of the propylene-based polymer include propylene. Polymer, block polypropylene, random polypropylene, etc. The weight ratio of the above polyethylene to propylene polymer 099120779 15 201114594 can be any suitable weight ratio according to the required (four) degree value and / or surface roughness. The ratio (polyethylene: propylene polymer) is preferably 10:90 to 90:10, more preferably 2:8〇~8〇: 2〇, especially good 3〇:7〇~. The above-mentioned t-ethylene and the propylene-based polymer exhibit a different melt flow rate. * When the polyethylene and the propylene-based polymer exhibit different melting flow rates, the surface layer-forming material is stretched and formed during the ship-melting state. The resin material with high wire flow rate is elongated, and (4) the resin with low flow rate is not easy to elongate. Therefore, it is possible to obtain a sea portion having a resin having a high smelting flow rate and a resin portion having a low melt flow rate. The surface layer of the island structure is divided. As a result, the surface layer exhibits a haze value and a surface roughness by the unevenness formed by the sea-island structure. The melt flow rate of the polyethylene is preferably 8 g / 1 〇 min -1 〇〇g/1〇 minutes' better 9g/10 minutes~80g/l〇 minutes, especially good 9g/i〇 minutes~5〇g/l〇 minutes, best 10g/10 minutes~5〇g/i 〇min. When the melt flow rate of polyethylene is less than 8 gM0 minutes, the difference in melt flow rate between the polyethylene and the above propylene-based polymer becomes small, and the haze value and surface roughness may become too small. When the melt flow rate of polyethylene is more than 10 g/l 〇 minutes, the haze value and surface roughness may become excessive. The melt flow rate can be measured by the method specified in JIS K721. The melt flow rate of the above propylene-based polymer is preferably 〇 lg / 1 〜 minutes to 7 g / 10 minutes, more preferably 0, 2 g / 10 minutes to 5 g / 1 〇 minutes, particularly good 〇 2g / 1 〇 minutes ~ 3g / I0 minutes, the best 〇.4g / 〇 minutes ~ 2 8g / 1 〇 minutes. Propylene 099120779 16 201114594 When the melt flow rate of the polymer is less than 〇.lg/1〇 minutes, the haze value and surface (4) build-up may become excessive. (4) The flow rate of the polymer melt flow is greater than g, the difference between the squeezing flow rate of the knife + ethylene and the above (4) polymer becomes small, and the haze value and surface roughness may become too small. μ The above-mentioned polyethylene and propylene-based polymer (IV) melt flow rate can be applied to the surface layer of the sea-island structure in which the sea portion is formed by polyethylene and the island portion is formed of propylene-based polymer. The haze value and the surface: seam of the laminated film can be controlled by adjusting the difference between the (iv) flow rate of the above polyethylene and the (iv) (four) rate of the above (iv) polymer. That is to say, when the difference between the flow rate of the glaze and the melt is large, the difference in the easiness of the surface layer forming material is large. 'Kazaki _ has a surface layer of the surface of the island structure, which can obtain a haze value and a large surface roughness. Laminated film. On the other hand, when the difference in the flow rate of the melt is small, the difference in the easiness of the surface layer forming material is small, and it is difficult to (10) have a surface layer of a clear island structure, and therefore, a simpleness value and a small surface roughness can be obtained. Laminated film. When the viscosity difference between the low-viscosity resin (showing high melt flow rate) and the high-viscosity resin (showing low melt flow rate) is small, it is difficult to obtain a clear deformation and development difference, and the island structure cannot be obtained, and low haze and surface roughness can be obtained. Sewing degree ^ phase film film ° other aspects, low viscosity resin (showing high melt flow rate), the same viscosity (four) (showing low (four) flow material) _ degree difference is large, can get a clear deformation flow difference, thus the island The structure is clear, and a laminated film with an ancient haze and a rough surface roughness can be obtained. The target haze and surface roughness can be controlled by the viscosity of the resin used: 099120779 17 201114594. In addition, in order to obtain high haze and rough surface roughness, the melting point of the high-viscosity resin of the (four) island structure is higher than that of the low-viscosity resin of the sea structure. The reason for this is that when the flow is extended, the structure is cooled, and the high-viscosity resin which is turned over is not cooled and solidified upon solidification, thus forming a clear island structure. Therefore, in terms of forming a surface having a high haze and a thick chain, it is preferred to use a propylene-based polymer as the yttrium-resin resin of the island structure, and it is preferred to use various low-melting resins such as polyethylene hydride as the sea structure. Low viscosity resin. Preferably, the surface layer has a melting temperature T m of two or more points in differential scanning calorimetry (DSC). Such a surface layer can be obtained by using a polyethylene having a different melting point and a propylene-based polymer. By using a polyethylene having a different melting point and a propylene polymer in the surface layer, the haze value and surface roughness of the laminated film can be adjusted by the difference in melting point. More specifically, in the film formation, when it is cooled and solidified after being thermally melted, the propylene polymer which is still dissolved is first solidified, and then the polyethylene having a low melting point is solidified. Therefore, when the difference in melting point is large, A clear sea-island structure is obtained in the surface layer, and as a result, a laminated film having a large haze value and a large surface roughness can be obtained. On the other hand, when the difference in melting point is small, it is difficult to obtain a surface layer having a clear island structure, and therefore, a laminated film having a small haze value and a small surface roughness can be obtained. Further, the above-mentioned melting temperature Tm can be measured by the method specified in JIS K7121. In the present specification, "there are two or more melting temperatures Tm" means that two or more refraction endothermic peaks are generated in the DSC curve. 099120779 18 201114594 The melting point of polyethylene is preferably 10 (rc~125t:, better coffee (2) hunger, and even better ll (TC~125t, especially good U5<t~i2 (rc. melting point of propylene polymer) Good $ Blow ~ War, Better (10) ~ Coffee ^ More Better Blow ~ Boots ^ Temple Jia Order ~ Best 13 (TC ~ 165 ΐ.

Polyethylene's bright spots and propylene polymer polymer's bright spots in this range, you can easily get rich invention _ face , that is, a surface layer having an arithmetic mean surface roughness & 〇·5μιη~2·θμιη, and a haze value of 13 5% to _. The laminate (IV) haze value and surface roughness of the present invention can be borrowed It is adjusted by the compatibility of the polyethylene and the propylene polymer in the surface layer. When the compatibility between the polyethylene and the propylene polymer is low, a clear island structure can be obtained in the surface layer. A laminate film having a simpleness value and a large surface roughness. On the other hand, when the compatibility is high, it is difficult to obtain a clear island structure, so A laminate film having a small haze value and a small surface roughness can be obtained. Commercially available products of the polyethylene and the propylene polymer can be used. Specific examples of the polyethylene which is commercially available include a product manufactured by Tosoh Corporation. "Petrothene 209"'s trade name "NOVATEC LD LJ803", "NOVATEC LD LC701", "NOVATEC LD LC720" manufactured by Nippon Polyethylene Co., Ltd., etc. Specific examples of commercially available propylene-based polymers 099120779 19 201114594 The product name "NOVATECPPEG8" manufactured by Nippon Polypropylene Co., Ltd. (Sakamoto POLYPRO Co., Ltd.), etc. The surface layer may contain any appropriate additives as needed, and may be used as an additive in the surface &(T 乂δ). For example, the above-described (Embodiment 3) can be used. In the above (Kappa 3), the surface layer contains a propylene-based polymer and an olefinic thermoplasticity. As the propylene-based polymer, for example, any appropriate propylene-based polymer can be used. For example, an acryl homopolymer, a polypropylene-free filament (10), etc., and a polypropylene obtained by using a metallocene catalyst, EPM, EBM, etc.) can be used as the acryl-based polymer. It is an olefinic U-thermal elastomer, if it is a so-called TpQ olefinic thermogenic elastomer, the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The hard segment portion formed by the polycarbonate belongs to the rubber component (hydrogenated (styrene) butyl rubber or ethylene propylene rubber (EPDM, car key segment). The weight ratio of the two rare t σ substances to the hydrocarbon-based thermoplastic elastomer, the haze value of the second Kangli force, and/or the surface coarse sugar content are any appropriate weight-to-weight ratio (propylene-based polymer: olefin system) The thermoplastic elastomer) is preferably 20:8G~ with 'better 3g: 7g~7(): 3(), especially good view ~ off. 099120779 201114594 It is preferred that the propylene-based polymer and the olefin-based thermoplastic elastomer have a different flow rate. When the propylene-based polymer and the olefin-based thermoplastic elastomer exhibit different melt flow rates, when the surface layer forming material is stretched in a hot melt state, the resin having a high melt flow rate is easily elongated. The resin having a low rate does not easily elongate, so that a surface layer having a sea-island structure in which a sea portion is formed by a resin having a high melt flow rate and an island portion is formed from a resin having a low melt flow rate can be obtained. As a result, the surface layer exhibits a haze value and a surface roughness by the unevenness formed by the island structure. The melt flow rate of the above propylene-based polymer is preferably from 5 g / 1 Torr to 100 g / 10 min, more preferably from 6 g / 10 min to 80 g / 10 min, particularly preferably from 7 g / 1 〇 min to 50 g / l 〇 min , the best 7g / 1 〇 minutes ~ 5 〇 g / 1 〇 minutes. When the melt flow rate of the propylene-based polymer is less than 5 g/1 〇min, the difference in melt flow rate between the propylene-based polymer and the above-described dilute-based thermoplastic elastomer becomes small, and the haze value and surface roughness may become too small. . When the melt flow rate of the propylene-based polymer is more than 100 g/10 minutes, the haze value and the surface roughness may become excessive. The melt flow rate can be measured by the method specified in JIS K7210. The melt flow rate of the olefin-based thermoplastic elastomer is preferably ο-ig/iomin to 4.9 g/10 min, more preferably 0 々/10 min to 4 g/i 〇 min, particularly preferably 0.2 g/10 min. 3g / 1 〇 pure, best 〇 4_ minutes ~ 2 8 coffee minutes. When the melt flow rate of the olefin-based thermoplastic elastomer is less than 0.1 gMO minutes, the haze value and the surface reduction may become excessive. _热热塑099120779 21 201114594 When the (iv) flowing material of the elastomer is more than 4.9 § / 1 () minutes, the difference between the glaring flow rate of the olefin-based thermoplastic elastomer and the above propylene-based polymer becomes small, and the haze value and The surface roughness may become too small. When the smelting flow rate of the propylene polymer and the chiral thermoplastic elastomer is within the above range, an island structure in which a sea portion is formed from a propylene polymer and an island portion is formed from a rare hydrocarbon thermoplastic elastomer can be obtained. Table / "The difference between the flow rate of the enthalpy polymer and the melt flow rate of the above olefin = plastic elastomer can control the haze value and surface roughness of the laminated film. That is, (4) when the difference in flow rate is large Table = the difference in the extensibility of the shaft material is larger 'a clear surface layer of the U.S. U. can be obtained. Therefore, the haze value and the surface roughness can be obtained. 2, on the other hand, the difference in the melt flow rate is higher. In the hour, the surface layer forming material (4) is small in the stretch of the wire, __ has a surface layer of the open-sea island structure. Therefore, the film can be obtained. The haze value and the surface (10)|degree of the layered low-viscosity resin ( It is difficult to show the difference in viscosity when the high melt flow rate is low and the flow rate is low; to Ming 19 (showing the momentum, the island structure cannot be obtained, and the laminated film with the correct deformation flow can be obtained. , low-mist and surface roughness is flat and high, and the flow rate is ...1 and 不1 is not toward the melt flow rate.) A viscosity position (showing a low rate of low-spirit) is paid to a clear deformation flow difference. It is clear that a high-mist 099120779 22 201114594 degree laminated film with a rough surface roughness can be obtained. The target haze and surface roughness can be controlled by the difference in viscosity of the resin used. In addition, in order to obtain high haze and thick chain The surface roughness, preferably the viscosity of the local viscosity resin belonging to the island structure is higher than the melting point of the low viscosity resin belonging to the sea structure. The reason is that the island structure first cools and solidifies during elongation flow, and the sea forms a high viscosity resin of the resin. It is not cooled and solidified at the time of curing, and thus a clear sea-island structure is formed. Therefore, in terms of forming a high haze and a rough surface roughness, it is preferable to use a hydrocarbon-based thermoplastic elastomer or the like as a high-viscosity resin of an island structure. Preferably, a low-point resin such as a propylene-based polymer is used as a low-viscosity resin of a sea structure. The surface layer is preferably two in differential scanning calorimetry (DSC). The above melting temperature Tm. Such a surface layer can be obtained by using a propylene-based polymer and an olefin-based thermoplastic elastomer having different melting points. By using a propylene-based polymer having different melting points and an olefin-based thermoplasticity in the surface layer. In the elastomer, the haze value and the surface roughness of the laminated film can be adjusted by the difference in melting point. More specifically, when the film is formed by heat-melting and then solidified by cooling, the high-melting olefin-based thermoplastic elastomer is first cured. Then, the propylene-based polymer having a low melting point is solidified. Therefore, when the difference in melting point is large, a clear island structure can be obtained in the surface layer, and as a result, a laminated film having a large haze value and a large surface roughness can be obtained. On the other hand, when the difference in melting point is small, it is difficult to obtain a surface layer having a clear island structure, and therefore, a laminated film having a small haze value and a small surface roughness can be obtained. Further, the melting temperature Tm can be determined by the method specified in JIS K7121. To determine. In the present specification, "having a melting temperature Tm of two or more points 099120779 23 201114594" means that two or more melting endothermic peaks are generated in the DSC curve. The melting point of the propylene-based polymer is preferably from 100 ° C to 140 ° C, more preferably from 110 ° C to 135 ° C, still more preferably from 120 ° C to 135 ° C, and particularly preferably from 125 ° C to 135 ° C. The melting point of the olefin-based thermoplastic elastomer is preferably from 120 ° C to 200 ° C, more preferably from 130 ° C to 190 ° C, still more preferably from 135 ° C to 180 ° C, and particularly preferably from 140 ° C to 170 ° C. The best 145 ° C ~ 165 ° C. The difference between the melting point of the propylene-based polymer and the melting point of the olefin-based thermoplastic elastomer is preferably from 5 ° C to 65 ° C, more preferably from 10 ° C to 60 ° C, particularly preferably from 15 ° C to 50 ° C. C. When the difference between the melting point of the propylene-based polymer and the melting point of the olefin-based thermoplastic elastomer is within such a range, the laminated film of the present invention can be easily obtained, that is, having an arithmetic mean surface roughness Ra of 0.5 μm to 2.0 μm. The surface layer and the laminated film having a haze value of 13.5% to 80%. The haze value and surface roughness of the laminated film of the present invention can be adjusted by the compatibility of the propylene-based polymer and the olefin-based thermoplastic elastomer in the surface layer. When the compatibility between the propylene-based polymer and the olefin-based thermoplastic elastomer is low, a clear sea-island structure can be obtained in the surface layer, and thus a laminated film having a large haze value and a large surface roughness can be obtained. On the other hand, when the compatibility is high, it is difficult to obtain a clear sea-island structure, and therefore, a laminated film having a haze value and a small surface roughness can be obtained. A commercially available product can also be used for the propylene-based polymer and the olefin-based thermoplastic elastomer. 099120779 24 201114594 Specific examples of the propylene-based polymer which is commercially available include, for example, "WINTEC WFX4" and "WINTEC WFX6" manufactured by Japan Polypropylene Co., Ltd., and the like.

The long-chain alkyl-based release agent contains a long-chain alkyl polymer. The long-chain alkyl-based molecule can be obtained by reacting a host molecule having a reactive group with a compound having an alkyl group reactive with the reactive group in any suitable heating solvent.
