Description

  The present invention relates to a decorative film for an electronic device and a method for manufacturing the same.

  Conventionally, decorative films such as mobile phones, digital cameras, televisions, personal computers, etc. used for display parts of electronic devices are decorated with letters, screen decorations, etc. on the back side of the decorative film substrate by silk printing etc. However, in this case, since the decorative layer is formed so as to rise from the surface of the film base material, a step is generated between the surface of the substrate that is not decorated and the decorative layer. Therefore, when a decorative film is attached to another hard plate such as glass via an optical double-sided tape, the surface on the substrate that has not been decorated is deformed as if pulled by the optical double-sided tape. As a result, the film has a distorted surface shape, which may cause uneven transmission.

  Therefore, the surface that has not been decorated and the upper surface of the decorative layer were filled with an ultraviolet curable resin, and the upper surface of the cured resin was covered with a separator film coated with a release agent, and pressed with rollers from above and below. Thereafter, there is a method of producing a decorative film by curing an ultraviolet curable resin by ultraviolet irradiation (see, for example, Patent Document 1). According to this, the decorative layer and the back surface of the film substrate are buried in the ultraviolet curable resin to eliminate the step, and the cured resin can be cured in a state of being smoothed by the separator film. And the optical double-sided tape which has permeability | transmittance is affixed on the upper surface of this ultraviolet curable resin, and it can be affixed on other hard boards, such as glass.

Japanese Unexamined Patent Publication No. 2012-22281 (7th page, FIG. 4)

  However, in the decorative film of Patent Document 1, since the separator film is peeled after the resin is cured by ultraviolet irradiation, and finally the optical double-sided tape is attached to the upper surface of the ultraviolet curable resin, the number of steps is large, and the manufacturing is performed. The work was complicated. In addition, a release agent is applied to the surface of the separator film in order to make it easier to peel off the separator film used as a mold material than the cured ultraviolet curable resin. As a result, a release agent is interposed between the ultraviolet curable resin and the optical double-sided tape, and there is a possibility that unevenness in light transmittance may occur in the completed decorative film.

  The present invention has been made paying attention to such problems, and an object of the present invention is to provide a decorative film excellent in light transmittance and a method for easily producing a decorative film excellent in light transmittance. And

In order to solve the above-mentioned problem, the method for producing a decorative film of the present invention includes
In the method for producing a decorative film, which is attached to a hard plate body such as glass and has a decorative layer on the back surface of the film base material, a cured resin is applied to the back surface of the film base material and the top surface of the decorative layer. Filled, the back surface of the film base and the decorative layer were embedded in the cured resin, and the adhesive layer used for adhering to the surface of the hard plate was pressed against the upper surface of the cured resin After the state or pressing operation, the curing resin is cured.
According to this feature, the back surface of the film base of the decorative film and the decorative layer are buried in the cured resin to eliminate the level difference, and the upper surface of the cured resin is directly pressed by the adhesive layer. Since the cured resin is cured after the operation, the upper surface of the cured resin can be surely smoothed. In particular, since the pressure-sensitive adhesive layer for attaching the decorative film to the plate is used as a mold material for the cured resin, the manufacturing process can be greatly simplified to increase the manufacturing efficiency. Moreover, since a release agent does not intervene between cured resin and an adhesion layer, the decorative film excellent in the light transmittance can be manufactured.

The pressure-sensitive adhesive layer is covered with a separator, and the pressure-sensitive adhesive layer is pressed against the cured resin by a predetermined pressurizing means through the separator.
According to this feature, since the adhesive layer is pressed against the cured resin by a predetermined pressurizing means through the separator, the upper surface of the cured resin is pressurized stably and evenly. The smoothness of the decorative film can be improved. Moreover, the separator which peels and uses when decorating a decorating film to hard board | plates, such as glass, can be effectively utilized for pressurization.

An optical double-sided tape is used for the adhesive layer, and an ultraviolet transmissive film is used as the separator.
According to this feature, by using an optical double-sided tape and an ultraviolet transmissive film, an ultraviolet curable resin can be used as the cured resin, and the ultraviolet curable resin can be cured immediately after being pressed or immediately after the pressing operation, thereby improving manufacturing workability. .

In order to solve the above problems, the decorative film of the present invention is
In a decorative film with a decorative layer on the back surface of the film base material, which is attached to a hard plate such as glass, the back surface of the film base material and the upper surface of the decorative layer are filled with a cured resin, The back surface of the film base and the decorative layer are buried in the cured resin, and the adhesive layer used for adhering to the surface of the hard plate is pressed against the upper surface of the cured resin or pressed It is manufactured by performing the hardening process of the said cured resin after an operation | work.
According to this feature, the back surface of the film base of the decorative film and the decorative layer are buried in the cured resin to eliminate the level difference, and the upper surface of the cured resin is directly pressed by the adhesive layer. Since the cured resin is cured after the work, the upper surface of the cured resin is surely smoothed. In particular, since the pressure-sensitive adhesive layer for attaching the decorative film to the plate is used as a mold material for the cured resin, the manufacturing process can be greatly simplified to increase the manufacturing efficiency. Moreover, since a mold release agent does not intervene between cured resin and an adhesion layer, the decorating film excellent in the light transmittance can be provided.

The pressure-sensitive adhesive layer includes a separator interposed between the pressure unit and the pressure-sensitive layer used when pressed against the cured resin by a predetermined pressure unit.
According to this feature, since the separator used when the adhesive layer is pressed against the cured resin by a predetermined pressing means is left in the adhesive layer, the decorative film is made of a hard plate such as glass. The separator can be peeled off when used for attachment.

The curable resin is a resin curable by ultraviolet rays, and the separator is made of a material having transparency.
According to this feature, since the cured resin can be irradiated with ultraviolet rays through the separator, the pressure-sensitive adhesive layer and the separator are pressed against the cured resin, and then the separator is coated on the adhesive layer. The cured resin can be cured as it is, and a decorative film with high production efficiency is provided.

In order to solve the above problems, the decorative film of the present invention is

It is the schematic which shows the process of forming an adhesion layer. It is an expanded sectional view which shows the coupling | bond part of ultraviolet curable resin and an adhesion layer. It is the schematic which shows ultraviolet irradiation. It is a sectional side view which shows after each manufacturing process.

  The form for implementing the decorating film which concerns on this invention is demonstrated below based on an Example.

  The decorative film according to the example will be described with reference to FIGS. Hereinafter, the lower side of FIGS. 3 to 8 will be described as the front side of the decorative film.

  The code | symbol 1 of FIG. 1 is a decorating film used for the display part of a smart phone. The decorative film of the present invention is not limited to this and can be applied to a display unit of an electronic device such as a mobile phone, a digital camera, a television, and a personal computer. For ease of explanation, the decorative layer 3, the ultraviolet curable resin 4, the adhesive layer 5 and the separator 8 which will be described later are shown thicker than the actual thickness.

  The decorative film 1 is provided with a decorative layer 3 serving as a screen display frame on the back surface 2a of the film substrate 2, and an ultraviolet curable resin 4 and an adhesive tape layer 5 described in detail later on the back surface of the decorative layer 3. Can be adhered to a hard plate such as glass constituting the display unit of the electronic device by the adhesive force of the adhesive layer 5. The film substrate 2 is formed of a transparent polyester film, polycarbonate, acrylic, glass, or a laminate of these materials.

  The pressure-sensitive adhesive layer 5 is formed of an acrylic gel-like resin or the like and has pressure-sensitive adhesive surfaces 5a and 5b on both front and back surfaces. Both the pressure-sensitive adhesive surfaces 5a and 5b are covered with a separator, and of these, the pressure-sensitive adhesive surface 5a. The separator 8 on the side is peeled off and attached to the upper surface of the decorative layer 3 (see FIG. 5).

  Further, the decoration layer 3 is formed with a hole 9a and a screen display opening 9b as shown in FIG. 1 according to the specifications of the electronic device, and the hole 9a is a camera built in the smartphone. It is provided in order to make it possible to use a function that requires transparency such as a flash or an illuminance sensor.

  The decorative film 1 has the decorative layer 3, the ultraviolet curable resin 4, the adhesive layer 5, and the separator 8 described above with respect to the back surface 2 a of the film base 2 by undergoing each process in a production line (not shown) as a whole. It is manufactured by being laminated in order. Moreover, in order to manufacture the several decorating film 1 at once, the large format film base material 2 (refer FIG. 2) is conveyed with the roller arrange | positioned at a manufacturing line, and is cut | judged to the predetermined shape after completion | finish of all the processes. It has become so.

  Each process in the production line will be described with reference to FIGS. First, the large-sized film base 2 is set on the production line, and is conveyed to the forming process of the decoration layer 3 shown in FIG. 3 by the rotation of the rollers 10, 10,.

  The step of forming the decorative layer 3 includes a roller-shaped printing plate 6 including a plurality of convex portions 6a formed in the shape of the predetermined decorative layer 3, and these convex portions 6a, 6a,. Each is coated with ink. Then, the printing plate 6 is pressed against the film substrate 2 conveyed by the roller 10 while rotating, whereby a plurality of decorative layers 3, 3,... Are formed on the large film substrate 2 at a time. .

  Depending on the specifications of the electronic device used, the decorative layer 3 is often arranged around the display unit for the purpose of preventing the wiring, screws, and the like arranged mainly around the display unit from being exposed. For this reason, it is generally formed so as not to have transparency. In addition, the decoration layer 3 is used also when giving characters, such as a logo, in addition to the decoration arrange | positioned at the peripheral part of the film base material 2. FIG.

  Although not specifically shown in the manufacturing process, the decorative layer 3 is applied in two layers by applying the ink twice, and the first decorative layer 3a is the second decorative layer. It is larger than 3b (see FIG. 8A). Therefore, the 2nd step of the decorative layer 3a, that is, the inner edge of the decorative layer 3 located on the back side of the decorative film 1 is hidden behind the first step of the decorative layer 3a and is not visually recognized from the outside, which is excellent in aesthetics.

  Next, the film substrate 2 on which the decorative layer 3 is formed is conveyed to the application step of the ultraviolet curable resin 4. As shown in FIG. 4, the coating process of the ultraviolet curable resin 4 includes a roller-shaped printing plate 7 including a plurality of convex portions 7 a formed substantially in the same shape as the outer edge shape of the decorative layer 3. The ultraviolet curable resin 4 is applied to each of the portions 7a, 7a,. Then, the printing plate 7 is pressed against the film substrate 2 and the decoration 3 that is conveyed by the roller 10 while rotating, so that the ultraviolet curable resin 4 is placed on the plurality of decoration layers 3, 3. Four layers are formed at a time.

  At this time, the convex portions 7a, 7a,... On which the ultraviolet curable resins 4, 4,... On the printing plate 7 are applied are solidly applied in the same shape as the outer edge shape of the decorative layers 3, 3,. 8B, the back surface 2a of the film substrate 2 and the upper surfaces 3c and 3d of the decorative layer 3 are filled with the ultraviolet curable resin 4, and the back surface 2a of the film substrate and the decoration The layer 3 is buried in the ultraviolet curable resin 4. At this time, the ultraviolet curable resin 4 also enters and fills the punched holes 9a and the screen display openings 9b in the decorative layer 3.

  Subsequently, the film substrate 2 is moved to the step of forming the adhesive layer 5 on the upper surface of the ultraviolet curable resin 4 after completion of the filling of the ultraviolet curable resin 4 described above. As shown in FIGS. 5 and 8C, the adhesive layer 5 is formed of a gel-like material having permeability, and has adhesive surfaces 5a and 5b on the front and back sides. Further, the separator 8 that covers the adhesive surface 5b is made of a film that is permeable and hardly deformed from the adhesive tape. The separator 8 may be made of a material that does not transmit other rays as long as it is a material that transmits at least ultraviolet rays.

  The step of forming the pressure-sensitive adhesive layer 5 on the upper surface 4a of the ultraviolet curable resin 4 includes a pressure roller 11 as a pressure means, and the pressure-sensitive adhesive layer 5 has a separator (not shown) peeled off from the pressure-sensitive adhesive surface 5a. The pressure-sensitive adhesive surface 5 a is pressed against the upper surface 4 a of the ultraviolet curable resin 4 with a predetermined force so as to be partially wound around the pressure roller 11. The adhesive layer 5 and the separator 8 are affixed so as to cover the entire surface of the large film base 2.

  As described above, since the separator 8 which is not easily deformed compared to the adhesive layer 5 is pressed against the ultraviolet curable resin 4 through the adhesive layer 5, the upper surface shape of the ultraviolet curable resin 4 is the shape of the surface 8 a of the separator 8 and the adhesive layer 5. And formed into a flat surface as shown in FIG.

  In addition, when observed with an electron microscope or the like, a fine uneven shape as shown in FIG. 6 can be confirmed on the surface of the adhesive surface 5 a of the adhesive layer 5, but the ultraviolet curable resin 4 before curing is softer than the adhesive layer 5. Therefore, the ultraviolet curable resin 4 enters the concave and convex shapes, and no gap is generated between the adhesive tape 5 and the ultraviolet curable resin 4.

  At this time, the ultraviolet curable resin 4 and the adhesive layer 5 are sandwiched between the pressure roller 11 and the transport roller 10 while being sandwiched between the separator 8 and the film substrate 2. Since the pressure roller 11 and the transport roller 10 are set to a predetermined separation distance, the thickness of the ultraviolet curable resin 4 and the adhesive layer 5 is molded to a predetermined thickness without being out of shape.

  Subsequently, the film substrate 2 shown in FIG. 7 is conveyed to the ultraviolet irradiation process. In the ultraviolet irradiation process, an ultraviolet irradiation device 20 is provided on the upper side, and ultraviolet rays are irradiated from the ultraviolet irradiation device 20 to the separator 8, the adhesive layer 5, and the ultraviolet curable resin 4 to cure the ultraviolet curable resin 4. At this time, since the separator 8 and the adhesive layer 5 are transmissive, the ultraviolet rays reach the entire surface of the ultraviolet curable resin 4, so that the ultraviolet curable resin 4 can be uniformly cured. Needless to say, the ultraviolet curable resin 4 has transparency at least after being cured.

  Then, after completion of the ultraviolet irradiation process, the film substrate 2 is cut to a cutting process (not shown), and the large film substrate 2 and the entire film substrate 2 are covered with a cutter device or the like in the cutting process. The attached adhesive layer 5 and separator 8 are cut out at a predetermined size and cutting position, and the decorative film 1 is completed. At this time, the decorative layer 3 that protrudes from the predetermined range during the flexographic printing and the ultraviolet curable resin 4 that protrudes outward from the decorative layer 3 due to the pressure between the pressure rollers 11 are simultaneously removed during the cutting step.

  The UV curable resin 4 may be applied in an amount that slightly protrudes outward from the decorative layer 3, and in this case, the resin can be thinned after the UV curable resin is cured by UV irradiation. In addition, since the portion protruding from the decorative layer 3 can be removed during the cutting process as described above, the equipment cost can be reduced without requiring an apparatus having extremely high accuracy in measuring the resin to be applied. .

  As described above, the decorative film of the present invention has ultraviolet rays on the back surface 2a of the film base material 2 and the upper surfaces 3c and 3d of the decorative layer 3 with respect to the film base material 2 with the decorative layer 3 applied to the back surface 2a. Steps can be eliminated by filling the curable resin 4 and burying the back surface 2a of the film base 2 and the decorative layer 3 in the ultraviolet curable resin 4, and further, the upper surface of the ultraviolet curable resin 4 is The upper surface of the ultraviolet curable resin 4 can be smoothly formed by pressing the permeable adhesive layer 5 to be adhered to the upper surface of a plate body such as glass (not shown). Moreover, since the adhesive layer 5 for attaching the decorative film 1 to the plate is used as a mold material of the ultraviolet curable resin 4, the manufacturing process can be greatly simplified and the manufacturing efficiency can be increased. Moreover, since a mold release agent does not intervene between the ultraviolet curable resin 4 and the adhesion layer 5 like the past, the decorating film 1 excellent in the light transmittance can be manufactured.

  In addition, since the adhesive layer 5 and the separator 8 used when the decorative film 1 is attached to a plate body such as glass can also be used as a mold material before curing of the ultraviolet curable resin 4, a separate mold material as in the past is used. The molding process of the UV curable resin and the mold material peeling process after molding can be omitted, and the manufacturing process can be greatly simplified to increase the manufacturing efficiency. Furthermore, since a mold release agent or the like is not required between the ultraviolet curable resin and the adhesive layer 5, unevenness in light transmission that occurs in the decorative film 1 after completion can be prevented. Furthermore, since the adhesive layer 5 is pressed against the ultraviolet curable resin 4 by the predetermined pressure roller 11 through the separator 8, the upper surface of the ultraviolet curable resin 4 is pressed stably and evenly. The smoothness of the decorative film 1 can be improved.

  Since the ultraviolet curable resin 4 is cured by ultraviolet irradiation after the pressure-sensitive adhesive layer 5 is directly pressed onto the upper surface of the ultraviolet curable resin 4, the ultraviolet curable resin is almost liquid before curing as shown in FIG. 6. 4 enters the fine uneven shape on the surface of the adhesive surface 5a of the adhesive layer 5, and the surface 4a of the ultraviolet curable resin 4 is cured in a shape along the surface of the adhesive surface 5a. Therefore, there is no gap between the pressure-sensitive adhesive layer 5 and the ultraviolet curable resin 4, and there is no unevenness in the light transmission in the decorative film 1 after completion. The decorative film 1 having a high bonding strength and excellent durability due to the physical uneven surface bonding between the adhesive layer 5 and the ultraviolet curable resin 4 as well as the area is provided. Further, since the pressure-sensitive roller 11 leaves the separator 8 used for pressing the ultraviolet curable resin 4 with the pressure-sensitive adhesive layer 11, the decorative film 1 is adhered to a hard plate such as glass. The separator 8 can be peeled off and used.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the said Example, although the ultraviolet curable resin is used for resin with which the back surface 2a of the film base material 2 and the upper surfaces 3c and 3d of the decoration layer 3 are filled, it is not restricted to what is hardened | cured by an ultraviolet-ray. For example, it may be a radicure resin such as an EB curable resin, a thermosetting resin, or the like. In this case, the resin is cured by providing respective steps such as electron beam irradiation and heat treatment instead of ultraviolet irradiation after the adhesion layer 5 is adhered. Let

  In addition, the ultraviolet curable resin 4 is formed in advance with a predetermined thickness on the adhesive surface 5a of the adhesive layer, and these are simultaneously stuck on the film substrate 2 and the decorative layer 3, thereby simplifying the manufacturing process. May be.

  Moreover, you may make it perform irradiation of an ultraviolet-ray from the lower surface side, ie, the film base material 2 side, using the raw material which has an ultraviolet-ray transmittance for the decoration layer 3. FIG.

  In addition, the decorative film 1 may be shipped in a state of being adhered to a plate body such as glass. For example, the printing plate is pressed directly on the upper surface of the ultraviolet curable resin 4 to form the adhesive layer 5, After a plate body such as glass is bonded to the adhesive surface 5b, a pressurizing step and an ultraviolet irradiation step with the pressure roller 11 are performed. According to this, since the separator 8 can be omitted, the material cost can be reduced.

  Moreover, the formation of the decoration layer 3 and the ultraviolet curable resin 4 is not limited to flexographic printing using a roller as in the above embodiment, and may be performed by, for example, screen printing, thermal transfer, ink jet printing, or the like.
