2. Description of the Related Art As a decorative material for the above-mentioned various uses, there are various types of base materials such as solid wood utilizing the beautiful design of natural wood and veneer obtained by thinly cutting wood. Veneer decorative materials applied to the surface of timber have been used most traditionally since ancient times, especially in Japan, where wood resources were abundant. However, these natural wood-grained decorative materials are mainly controlled by natural coincidence,
In addition to instability in quality, the depletion of natural timber resources in the modern era has led to problems such as a decrease in the supply of solid wood and veneer, which have beautiful wood grain design, and a rise in prices. Have been. Due to such a background, a method of directly printing a beautiful grain pattern on a surface of inferior wood grain design or various base materials having no design property, or attaching a separately prepared grain decorative paper. As a result, cosmetic materials to which beautiful wood grain design is artificially added have been produced and supplied in large quantities for a long time.

[0003] Cosmetic materials to which such artificial design is added have the advantage that products of a certain quality can be supplied in large quantities at low cost, but they are not as good as natural wood-grained cosmetic materials. However, it did not cover design and durability. In other words, while the natural grain has a three-dimensional effect due to the difference in texture between the spring and autumn parts and the subtle unevenness, the wood grain by printing is only planar. In terms of design, it is inferior to natural wood. In addition, natural wood grain is continuous not only on the surface but also inside the wood, so the wood grain design is not lost even if the surface is slightly worn due to long-term use, whereas the wood grain pattern layer is printed. Is based on an extremely thin layer of printing ink of only a few μm at most, and if the picture layer is lost due to abrasion, the design of the grain is naturally lost. In view of such a problem, various methods have been devised in order to make the grain of the printed grain closer to the grain of natural wood in terms of design and durability.

[0004] One of the various devices described above is a technique called emboss printing. This is, first, on the entire surface of the base material for decorative material or base paper for decorative paper, a pattern imitating natural wood grain is printed by a normal printing method or the like to form a pattern layer, and then the natural wood grain This is a technique of forming a raised print layer by performing printing on a portion corresponding to a convex portion using a printing ink having a high solid content so as to be raised from the surroundings. By this technique, it is possible to give a three-dimensional effect due to the unevenness of the wood grain by printing, and by selecting a vehicle of printing ink for embossing printing and adding a polishing agent or matting agent, etc., the gloss of the surface after printing is improved. Make the state different from the surroundings,
It is also possible to express the difference in texture between the spring wood part and the autumn wood part. In addition, since the wear of the surface of the decorative material generally proceeds from the protruding end of the convex portion, the pattern of the pattern layer by the normal printing method of the base is not lost unless the raised print portion is completely lost due to wear. . Therefore, at least the life of the design by the picture layer can be remarkably prolonged as compared with that without the embossed printing. Further, in order to further improve the durability, as a printing ink for embossing printing, one using a cross-linking curable resin as a vehicle may be used, and / or high-hardness wear-resistant particles such as silica or alumina. Various contrivances, such as using the one added, have also been made.

As described above, the case of grain is described.
The application of the embossed printing method is not limited to wood grain. That is, in recent years, consumer preferences have diversified, and, for example, decorative materials having various designs other than wood grain, such as stone patterns, cloth patterns, and abstract patterns, have been widely used. However, even in the case of various kinds of decorative materials, it is possible to achieve a high degree of design expression such as three-dimensional appearance and material feeling, and also to improve the durability such as abrasion resistance. Has been widely applied.

[0006] In recent years, as the values of society have fluctuated greatly, for example, people's lifestyles have become more westernized, and the standard of living has become more and more diversified in tastes and preferences. For such various kinds of decorative materials, it is required to add not only design properties and durability but also various special functionalities. As an example, for example, a function of stain resistance can be given. This is because, for example, when contaminants such as soy sauce, sauce, and edible oil adhere to the surface of a cosmetic material in a kitchen or the like of a general house, the attached portion is colored or changes in luster, thereby impairing the design. The problem is that the pollutants are hard to adhere,
In addition, there is a demand for a cosmetic material that can be easily removed by wiping or the like even if it adheres. As one of the solutions to this problem, a method of forming a top coat layer made of an aminoalkyd resin or an acrylic urethane resin on the surface of a decorative material has been put to practical use.

[0007] However, even if the decorative material having such a top coat layer is removed by wiping or the like within a short time after the adherence of the contaminant, although the effectiveness is certainly recognized, it is difficult to adhere to the contaminant. If left undetected for a long time, the contaminants permeate the overcoat layer over time and reach the picture layer, the base paper, or the base material, and stains occur there. And once the contamination has progressed so far,
After that, when the contaminants on the surface of the overcoat layer are removed, it is no longer possible to remove stains on the picture layer, base paper or substrate. Such a problem is particularly remarkable in the case of a contaminant containing a large amount of oil and fat, such as a sauce and an edible oil, and is regarded as a so-called “oil stain”. In addition, for example, when processing or constructing a cosmetic material in a processing factory or a construction site, if a solvent for diluting a paint or an adhesive adheres to the surface of the cosmetic material, the solvent also becomes stained, or the solvent is used. There has been a problem that a phenomenon such as so-called "pattern running" occurs in which the picture layer becomes indistinct due to dissolution of the ink in the picture layer.

[0008] As one of the measures against the above problems,
Instead of direct printing or sticking of decorative paper on a base material such as a wood base material, for example, contamination of oils and fats such as a thermoplastic resin film, a thermoplastic resin film laminated paper, a metal foil, a metal foil laminated paper, etc. A method of using a decorative sheet in which a pattern is printed on the surface of a non-permeable sheet having no permeability to substances, solvents, and the like may be considered. However, even if a decorative sheet having a pattern of wood grain or the like and a raised print on the surface of the non-permeable sheet is used, the problem of the stain of the non-permeable sheet and the base material may be solved. Problems such as layer stains and pattern run-off cannot be solved.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of a cosmetic material of the present invention will be described in detail with reference to the drawings. 1 to 12
1 is a side sectional view showing an embodiment of a decorative material of the present invention.

The cosmetic material of the present invention, as exemplified in FIG.
A decorative material comprising at least a pattern layer 3 for design expression by a desired color pattern and a raised print layer 1 for imparting design expression such as three-dimensional appearance and material feeling and wear resistance. By providing the transparent thermoplastic resin film layer 2 between the picture layer 3 and the raised print layer 1, contaminants adhering to the surface of the decorative material penetrate into the picture layer 3 and the base material 4, Effectively prevents the phenomenon of stains, and therefore has much better stain resistance than conventional cosmetics of the same type, and retains good design properties over a long period of time even under severely polluted use environments It is a realizable cosmetic material.

In the decorative material of the present invention, a functional layer 5 for exhibiting various optional functions required according to the use of the decorative material is provided on the transparent thermoplastic resin film layer 2.
Can also be provided. The functional layer 5 may be provided between the transparent thermoplastic resin film layer 2 and the raised print layer 1 (FIG. 2), or may be provided on the transparent thermoplastic resin film layer 2 and the raised print layer 1. Good (Figure 3). Further, it may be provided on a portion of the transparent thermoplastic resin film layer 2 where the raised print layer 1 is not provided (FIG. 4). In any of these configurations, as long as the raised print layer 1 is not completely worn out, at least the functional layer 5 in the portion where the raised print layer 1 is not provided will not be worn away. It can withstand abrasion and maintain its functionality.

Raised print layer 1 in the decorative material of the present invention
The material is not particularly limited, and any material similar to that used for the conventional embossed print layer 1 of the decorative material can be used. However, from the viewpoint of the wear resistance effect, it is preferable to use a material having high hardness. In particular, in the case where the functional layer 5 is provided, in order to protect the functional layer 5 from abrasion and sufficiently exhibit the effect of maintaining the functionality for a long period of time, the embossed print layer 1 must have at least a function. It is preferable to be made of a material having a higher hardness than the conductive layer 5.

As described above, from the viewpoint of imparting sufficient hardness to the embossed print layer 1, the embossed print layer 1 may be, for example, a melamine resin, a urethane resin, an epoxy resin, a phenol resin, a urea resin, an alkyd resin. Resin, a thermosetting resin such as a polyester resin, or a composition containing at least a curable resin such as an ionizing radiation curable resin such as an acrylate resin or a methacrylate resin, or, for example, silica, alumina, It is preferable to use a composition containing at least abrasion-resistant particles such as glass, calcium carbonate, barium sulfate, zirconium oxide, silicon nitride, silicon carbide, zeolite, shirasu balloon, diatomaceous earth, and more preferably both.

The thickness of the embossed print layer 1 is not particularly limited, but is generally at least 5 μm in order to sufficiently exhibit design effects such as three-dimensional appearance and material appearance and effects such as abrasion resistance.
m or more is necessary. Although the three-dimensional feeling and the wear resistance are improved as the thickness is increased, the adhesion to the transparent thermoplastic resin film layer 2 is reduced even if the thickness is too large, and cracks and peeling are likely to occur during laminating or bending. There is a problem, and it is generally difficult in terms of printing technology to print a raised image exceeding 100 μm. Therefore, from the viewpoints of both performance and productivity, it is generally appropriately designed within the range of about 10 to 50 μm according to the required performance, and the most preferable range is about 20 to 30 μm. The embossed print layer 1 may be colorless or colored in an appropriate color, or may be provided in synchronization with a picture of a picture layer 3 described later.

The method of forming the embossed print layer 1 is not particularly limited, but is most commonly provided by a gravure printing method or a screen printing method using a printing ink composition having a high solid content. In order to improve the adhesiveness between the embossed print layer 1 and the transparent thermoplastic resin film layer 2, if necessary, the surface of the transparent thermoplastic resin film layer 2 is printed before the embossed print layer 1 is formed. Corona discharge treatment,
Surface treatment such as ozone treatment, plasma treatment, ionizing radiation treatment, dichromic acid treatment, anchor or primer treatment may be performed.

As described above, the transparent thermoplastic resin film layer 2 is provided for the purpose of improving stain resistance and solvent resistance in the decorative material of the present invention. The material is not particularly limited, and it is sufficient that at least the picture layer 3 is a transparent or translucent thermoplastic resin film having transparency that can be seen through, and appropriately selected from conventionally known arbitrary materials. Can be. Specifically, for example, a film or sheet made of an olefin resin, a polyester resin, a polyvinyl chloride resin, an acrylic resin, a styrene resin, or the like can be used.

Although the thickness of the transparent thermoplastic resin film layer 2 is not particularly limited, it is generally required to be at least 1 μm or more from the viewpoint of stain resistance and solvent resistance. In consideration of the feeling of painting, feeling of depth, feeling of depth, etc., it is preferable that the thickness is at least 10 μm or more. The upper limit is about 500 μm from the viewpoint of cost and workability. Generally, it is most desirable that the thickness be in the range of about 25 to 150 μm.

Further, the transparent thermoplastic resin film layer 2 comprises:
It may be composed of a mixture, laminate or composite of a plurality of layers made of the same or different materials. For example, as shown in FIGS. 5 and 6, a two-layer structure in which a surface transparent thermoplastic resin film layer 21 and an intermediate transparent thermoplastic resin film layer 22 are laminated in order from the embossed print layer 1 side to the picture layer 3 side. It can be. As described above, when the transparent thermoplastic resin film layer 2 is composed of a laminate of a plurality of layers, characteristics that are difficult to achieve with a single-layer thermoplastic resin film can be achieved by two thermoplastic resin films complementing each other. There is an advantage of becoming.

For example, such a cosmetic material is required to have a surface hardness so as not to be easily damaged even if it rubs against a human body or an object during use. It is required to have a moderate flexibility. However, when the transparent thermoplastic resin film layer 2 is made of a resin having a high hardness, the surface hardness is satisfactory, but the workability is poor. On the other hand, when the transparent thermoplastic resin film layer 2 is made of a flexible resin, the workability is good but the surface hardness is unsatisfactory. In such a case, the transparent thermoplastic resin film layer 2 is composed of two layers: a surface transparent thermoplastic resin film layer 21 made of a high-hardness resin, and an intermediate transparent thermoplastic resin film layer 22 made of a flexible resin. This makes it possible to easily realize a cosmetic material that satisfies both the hardness required for the surface during use and the flexibility required for processing.

In the case of the above example, the surface transparent thermoplastic resin film layer 21 and the intermediate transparent thermoplastic resin film layer 2
The material of No. 2 is not particularly limited. For example, it is also possible to use a completely different resin-based thermoplastic resin film in combination. In this case, as the surface transparent thermoplastic resin film layer 21, for example, a biaxially stretched polyethylene terephthalate film or an ethylene-vinyl alcohol copolymer resin A film made of a highly rigid resin such as a film may be used, and a film made of a flexible resin such as a polyvinyl chloride resin or a polyolefin resin may be used as the intermediate transparent thermoplastic resin film layer 22, for example.

It is also possible to combine the same resin materials having different physical properties depending on the composition, additives, processing conditions, and the like. For example, an unplasticized rigid polyvinyl chloride resin film and a soft plasticized plasticizer may be used. Polyvinyl chloride resin film, biaxially stretched polyester resin film and amorphous polyester resin film, highly crystalline homopolypropylene resin film and soft polypropylene resin film containing amorphous or rubber component, hard without rubber component The surface transparent thermoplastic resin film layer 21 and the intermediate transparent thermoplastic resin film layer 22 can be constituted by a combination of an acrylic resin film and a soft acrylic resin film added with a rubber component.

The thicknesses of the surface transparent thermoplastic resin film 21 and the intermediate transparent thermoplastic resin film layer 22 are not particularly limited, and may be appropriately distributed and designed so as to realize desired physical properties of the whole decorative material. Generally, the thickness of the surface transparent thermoplastic resin film layer 21 is about 10 to 50 μm,
The thickness of the intermediate transparent thermoplastic resin film layer 22 is set to 20 to 1
The thickness is preferably about 00 μm.

As described above, when the transparent thermoplastic resin film layer 2 is composed of a laminate of a plurality of layers, the lamination method is not particularly limited. For example, a dry lamination method or a wet lamination method using an adhesive, Any conventionally known laminating method such as a heat laminating method, an extruding laminating method, a polysand laminating method, and a co-extrusion method with or without an adhesive can be appropriately employed. The method of laminating the transparent thermoplastic resin film layer 2 on the substrate 4 is almost the same,
There is no particular limitation.

The picture layer 3 is provided for the purpose of giving the decorative material of the present invention a design with a desired color pattern. There is no particular limitation on the type of the pattern, for example, a wood pattern, a stone pattern, a cloth pattern, an abstract pattern, a geometric pattern, or the like, as desired. If a color pattern is not required, it may be a plain solid color. . The formation material and the formation method of the picture layer 3 are also optional, but are generally provided by a suitable printing method or coating method using a suitable printing ink or paint as conventionally known. When the concealing property with respect to the base is required, a concealing layer made of a concealing ink or paint containing a large amount of a concealing pigment such as an inorganic pigment or a metal powder pigment can be provided in addition to the color pattern.

The pattern layer 3 may be provided beforehand on the back surface of the transparent thermoplastic resin film layer 2 before lamination with the base material 4 or, conversely, on the lamination with the transparent thermoplastic resin film layer 2. It may be provided beforehand on the back surface of the base material 4. Of course, both can be used in combination. In order to improve the adhesiveness between the picture layer 3 and the transparent thermoplastic resin film layer 2 or the base material 4, if necessary, before forming the picture layer 3, the back or base of the transparent thermoplastic resin film layer 2 may be used. The surface of the material 4 may be previously subjected to a surface treatment such as a corona discharge treatment, an ozone treatment, a plasma treatment, an ionizing radiation treatment, a dichromic acid treatment, an anchor or a primer treatment.

The base material 4 is exactly the same as that of a conventional decorative material, and can be appropriately selected from conventionally known arbitrary materials. Specifically, for example, tissue paper, titanium paper, resin-impregnated paper, resin-mixed paper, paper-reinforced paper, bleached or unbleached kraft paper, linter paper, woodfree paper, coated paper, inorganic paper,
Various types of paper such as flame-retardant paper, paperboard, Japanese paper, and woven or nonwoven fabrics made of natural fibers, recycled fibers, synthetic fibers, inorganic fibers, etc., olefin resins, polyester resins, polyvinyl chloride resins, acrylic resins Resins, films or sheets or sheet materials or molded articles made of synthetic resins such as styrene resins,
Wood base material such as wood veneer, plywood, glulam, particle board, medium density fiber board, plaster board, calcium silicate board, asbestos cement board, wood wool cement board, glass fiber reinforced concrete board, lightweight cellular concrete board, etc. Inorganic base material,
Metallic base materials such as iron, copper, brass, stainless steel, and aluminum can be used, and a base material obtained by mixing, laminating, or compounding a plurality of materials selected from these can be used as necessary. Can also.

As the functional layer 5, a material having any desired function can be appropriately used according to the intended use of the decorative material. Specifically, for example, pollution prevention function, antibacterial function, antifungal function, insect repellent function, deodorant function, volatile organic substance removing function, fragrance function, moisture absorption and desorption function, photocatalytic function, superhydrophilic function, conductive function, An ion generating function and the like can be given. Of course, two or more of these functions may be provided. As the materials having these functions, any conventionally known materials can be appropriately used. Also, if possible, the raised print layer 1
The functional layer 5 may have the same or different functionality as that of the functional layer 5, so that a cosmetic material having more excellent functionality can be obtained.

Since the functional layer 5 is protected from abrasion by the raised print layer 1, it is not always necessary to be made of a material having a particularly high hardness. However, even if the raised printing layer 1 is not damaged, the functional layer 5 may be damaged and the design may be impaired. Considering that the part and the concave part may be simultaneously worn, it is not impossible to use a material having the highest possible hardness. In addition to the wear resistance and scratch resistance, the functional layer 5 is also heat-curable resin or ionizing radiation-curable as in the case of the raised print layer 1 from the viewpoints of stain resistance and solvent resistance. It is desirable to contain at least a curable resin such as a resin.

The thickness of the functional layer 5 and the method of forming the functional layer 5 are not particularly limited, and may be appropriately designed according to the characteristics of the functional material that should exhibit the desired functionality. Generally, the thickness of the functional layer 2 is often selected from the range of about 0.1 to 10 μm. The method for forming the functional layer 2 is as follows.
When the functional layer is supplied in the form of a coating liquid or can be dissolved or dispersed in an appropriate solvent, it can be applied under a reduced pressure, such as a coating method, a melt extrusion lamination method, an injection molding method, and a thermal spraying method for a thermoplastic substance. As long as it is a substance that can be vaporized, it can be appropriately selected from various conventionally known film forming methods such as a vacuum evaporation method and a sputtering method.

[0038] The cosmetic material of the present invention is made of synthetic resin, wood,
It also includes a decorative sheet to be used by sticking to the surface of an inorganic or metal based decorative material substrate. In such a decorative sheet, the base material 4 is, for example, paper, woven or non-woven fabric, synthetic resin film or sheet, wood veneer,
Thin and flexible sheet material such as metal foil (base sheet 4
Use 1). In addition, the transparent thermoplastic resin film layer 2
If the decorative sheet has a sufficient strength as a support for the decorative sheet, it is also possible to adopt a configuration in which the base material 4 is omitted as illustrated in FIGS. As described above, the decorative sheet provided with the embossed print layer 1 also has the advantage that the duck at the time of lamination to the decorative material base material 42 is less noticeable and has good workability.

As shown in FIGS. 11 and 12, such a decorative sheet is used as a decorative material of a final product in a form of being adhered to the surface of various decorative material base materials 42 via an appropriate adhesive 6. Is done. The type of the adhesive 6 is not particularly limited, and is appropriately determined in consideration of the adhesiveness and durability between the surface of the decorative material base material 42 and the back surface of the decorative sheet (the pattern layer 3 or the base material sheet 41). Generally, a wood-based base material such as plywood or a medium-density fiberboard is often used as the decorative base material 42,
In such a field, an aqueous emulsion adhesive such as vinyl acetate is often used as the adhesive 6. When the picture layer 3 or the base sheet 41 is made of a material having poor adhesion to the aqueous emulsion adhesive, a primer layer made of a material having excellent adhesion to the aqueous emulsion adhesive is provided on the back surface. It is good to provide.

Further, on the stain-resistant layer, a two-component curable urethane-based resin containing silica powder as abrasion-resistant particles is dried by a gravure printing method to a thickness of 20 μm. Emboss print was applied. Thereafter, the non-printed surface of the printed polypropylene resin film is subjected to corona discharge treatment, and then the surface and the surface opposite to the raised print surface of the printed polyethylene terephthalate resin film are two-component curable urethane dry laminates. The laminate was dry-laminated via an adhesive to produce a decorative sheet as the decorative material of the present invention.
