Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer foil for producing a product having an excellent design effect by imparting a fine uneven pattern on the surface of various products, and further to a decorative glass using the transfer foil. is there.

[0002]

2. Description of the Related Art Various transfer foils having a transfer layer laminated on the surface of a base material sheet are known, and these transfer foils are heated from the base material sheet side to bond the transfer layer to a transfer target. After that, the base material sheet is peeled off to transfer the transfer layer to the transfer target. Among them, there is also proposed a transfer foil in which an uneven pattern is formed on the surface of the transfer layer so that the surface of the transferred object emits rainbow color due to oblique light after transfer. (JP-A-2
There is also proposed a method of manufacturing a decorative glass by forming a semi-transparent metal vapor deposition film or the like on a base material sheet having an uneven pattern and then attaching the sheet to a glass substrate. In addition, after forming a release layer on the substrate film, a transparent lacquer coating layer having an uneven pattern is formed, a metal deposition film is provided on the uneven pattern, and a transfer foil having an adhesive layer is also proposed. There is.

[0003]

However, a transfer foil in which an uneven pattern is formed on the surface of the transfer layer so that the surface of the transferred material emits rainbow color due to oblique light after transfer, has a poor three-dimensional effect.
It does not become excellent in design. Further, since the thermoplastic resin is embossed by heating, it is difficult to reproduce a deep uneven shape, and the embossed shape is also deformed due to aging. The method of manufacturing a decorative glass by forming a semi-transparent metal deposition film on a base material sheet with an uneven pattern and then attaching this sheet to a glass substrate is a good way to attach the sheet to the glass during on-site construction. There is a problem in workability. A transparent lacquer coating layer with a concavo-convex pattern is formed on a base film, an aluminum (hereinafter referred to as Al) vapor deposition film is provided on the concavo-convex pattern, and a transfer foil with an adhesive layer further has an Al vapor deposition film of 500Å Since it is thick, the transfer layer becomes opaque, and a transferred material having a three-dimensional effect and excellent in design cannot be obtained.

The present invention solves these problems and provides a transfer foil having a three-dimensional effect and excellent in designability, which is not seen in conventional transfer foils. By using the transfer foil, the design effect is excellent. It is intended to obtain a transferred material such as decorative glass.

[0005]

[Means for Solving the Problem] A resin sheet having a fine uneven surface, a thin film layer having a light transmittance of 10 to 90%, and a resin layer containing a glittering substance are sequentially formed on a substrate sheet. And a pattern layer and an adhesive layer formed on the resin layer containing the glittering substance of the transfer foil. Further, the transfer foil is characterized in that the resin layer having the fine uneven surface is an ionizing radiation curable resin. Then, by using the transfer foil, the surface of the resin layer containing the glittering substance is transferred to the surface of the primer layer of the glass substrate on which the primer layer is formed, and then the surface of the transferred fine resin layer A concealing layer was formed on the to prepare a decorative glass.

[0006]

According to the present invention, since the fine uneven pattern formed on the base sheet is formed of the ionizing radiation curable resin by using the roll intaglio, the desired uneven pattern can be accurately reproduced. Becomes Therefore, the transfer layer composed of the semitransparent metal thin film layer and the resin layer containing the glittering substance formed thereon faithfully reproduces the concavo-convex pattern of the ionizing radiation curable resin and is transferred to the transfer target. Therefore, by virtue of the presence of the thin, light-transmitting metal thin film layer formed on the concavo-convex pattern, it is possible to obtain a transferred material having a three-dimensional appearance and excellent design which cannot be seen in the conventional transfer foil. Moreover, by using this transfer foil and transferring to a glass plate, a decorative glass having a high design effect can be obtained.

With the above-described structure, an uneven pattern is imprinted on the glittering resin layer, and a semitransparent thin film layer is further adhered to the imprinted uneven pattern 12a. At the time of transfer, it is transferred together with the imprinted uneven pattern. It will be transferred to the transferred material as a layer.

In the transfer foil 1, the translucent thin film layer 13 and the glittering resin layer 14 containing the glittering substance 15 are transferred as a transfer layer to a transfer target. Also, the transfer foil 2 is
The semitransparent thin film layer 13, the glitter resin layer 14, and the pattern 16 are transferred to the transfer target through the adhesive layer 17. for that reason,
In order to improve the releasability of the release layer, a release layer or a release layer is provided on the uneven pattern 12 made of an ionizing radiation curable resin, and then a semitransparent thin film layer 13 is formed to produce a transfer foil. There is a case.

Next, the case of producing decorative glass using the transfer foil of the present invention will be described. First, as shown in FIG. 3, the primer layer 18 is provided on one surface of the glass plate 19, and the surface of the adhesive layer of the transfer foil 2 shown in FIG. 2 is overlaid on the primer layer. Next, after the transfer foil and the glass plate are adhered to each other with a heating roll or the like, the base material sheet 11 having the concavo-convex pattern formed thereon is peeled off, and the transfer layer is transferred to the glass substrate.
By peeling off the base material sheet 11 on which the concavo-convex pattern is formed, the translucent thin film layer 13 is transferred together with the concavo-convex pattern 12a formed on the glittering resin layer. An uneven pattern having a thin film layer is formed. Furthermore,
As shown in FIG. 4, the concealing layer 20 is formed on the transfer layer to produce the decorative glass 3.

The method of manufacturing the transfer foil of the present invention and the material of each layer of the transfer foil will be described in more detail. As a material for the base sheet, a sheet or film having heat resistance and good dimensional stability can be used. For example, polyester such as polyethylene terephthalate, polyamide such as nylon, polyvinyl chloride, acrylic resin such as polymethyl methacrylate, polypropylene, cellulose triacetate, plastic film or sheet such as cellophane, or copper,
Metal foils such as iron and aluminum, paper, etc. may be mentioned.

As the sheet having the concavo-convex pattern formed on the base sheet, an ordinary embossed sheet can be used. However, as shown below, a roll intaglio plate is used to cure the base sheet with ionizing radiation. By forming the concavo-convex pattern with the functional resin, the concavo-convex pattern with high accuracy can be formed, and the transfer foil excellent in designability can be manufactured.

A method of forming an uneven pattern on a substrate sheet with an ionizing radiation curable resin using a roll intaglio (hereinafter referred to as a drum printing method) will be described below. In the drum printing method, as shown in FIG. 5, an ionizing radiation curable resin liquid 23 is coated on a roll intaglio 21 engraved with a desired uneven pattern by a nozzle type coating device 24 and cured by a nip roll 25. Resin liquid 23 is completely filled in the concave portion 22 of the roll intaglio. At the same time, the base film 11 is brought into close contact with the surface of the roll intaglio plate via the ionizing radiation-curable resin liquid 23, and ionizing radiation is irradiated from above the film by using the ionizing radiation irradiation device 27 to the concave portion 22 of the roll intaglio plate. Ionizing radiation curable resin 23a that is cured on the base film 11 while curing the filled resin liquid
After adhering, the base film 11 is peeled off from the roll intaglio 21 by the peeling roll 26, and the concavo-convex pattern 12 made of the cured ionizing radiation curable resin is formed on the base film 11.

As the concavo-convex pattern formed on the roll intaglio, a concavo-convex shape composed of a line-shaped groove-shaped straight line group is mainly used. The line-shaped uneven shape is an assembly of uneven shapes including parallel lines running in the same direction and unevenness or grooves forming parallel straight lines or curved lines in a flat curve region. There is also a shape in which the angles formed by the directions of the straight line groups or the curved line groups that are adjacent to each other across the boundary between any two regions are different.

The line group forming the concavo-convex pattern is composed of a continuous wave-shaped curve group so that the convex directions of the adjacent arcs alternate in the arc of 1/4 of the entire circumference. There is also a parallel curve group in which curves are connected and the curves are moved in parallel. As the parallel curve group, there is one in which a plurality of connected curve units such as a sine wave curve, a cycloid curve, an elliptic function curve, a Bessel function curve, and an arc are arranged in parallel with each other.

To form an uneven shape on the substrate film,

For example, it is also possible to form an uneven shape by ink-jet printing using a thermoplastic resin, a thermosetting resin, or the like, using gravure printing or screen-printing method. As the ink composition, in addition to these resins, a colorant such as a dye or a pigment, a filler, a plasticizer, a stabilizer, or the like is appropriately added depending on the purpose of the uneven shape. Also,
An ultraviolet curable resin or an electron beam curable resin can also be used as the ink resin. Alternatively, the concavo-convex shape can be formed directly on the substrate sheet itself by a method such as press working or sandblasting. Furthermore, in order to improve physical properties such as solvent resistance, chemical resistance, and abrasion resistance of the uneven shape, the topcoat layer may be provided with a resin suitable for the purpose.

The above compounds may be used alone or in admixture of two or more, if necessary, but in order to impart ordinary coating suitability to the resin composition, the above prepolymer or oligomer may be used in an amount of 5
95% by weight or more of the monomer and / or polythiol
It is preferable to set the content to be not more than weight%.

When flexibility of the cured product is required when selecting the monomer, the amount of the monomer may be decreased or the monofunctional or bifunctional acrylate monofunctional may be used within a range that does not hinder the coating suitability. A structure with a relatively low cross-linking density is used using a polymer. Also,
When heat resistance, hardness, solvent resistance, etc. of the cured product are required, increase the amount of the monomer or use a trifunctional or higher functional acrylate-based monomer within a range that does not hinder the coating suitability. A structure having a high crosslink density is preferable. Monofunctional and bifunctional monomers and 3

Hereinafter, more detailed description will be given with reference to specific examples. Example 1 A polyethylene terephthalate (hereinafter referred to as PET) film having a thickness of 25 μm (“HP-7” manufactured by Teijin Ltd.)
Using the above as a base material, a film having an uneven pattern was produced by the drum printing method under the following conditions.・ Roll intaglio; 2 depth by direct etching
A line-shaped concavo-convex pattern with 0 μm and an interval of 100 μm was formed. -Ultraviolet curable resin: 3% of silicone resin added to urethane resin "SEICA BEAM EX-880926B" manufactured by Dainichiseika Co., Ltd.・ Ultraviolet irradiation device; high pressure mercury lamp with ozone (output 12
0 W / cm) is used.

As shown in FIG. 5, the ultraviolet curable resin liquid 2
3 is coated on the roll intaglio 21 having a concavo-convex pattern by the nozzle type coating device 24, and the UV curable resin liquid 23 is filled in the recess 22 of the roll intaglio by the nip roll 25.
At the same time, the base film 11 is brought into close contact with the surface of the roll intaglio plate 21, and ultraviolet rays are radiated from the ultraviolet ray irradiating device 27 for 2 seconds to cure the resin liquid filled in the recesses 22 of the roll intaglio plate. After the cured ultraviolet curable resin 23a is adhered to the material film 11, the base film 11 is removed from the roll intaglio 21 by the peeling roll 26.
Was peeled off, and a concavo-convex pattern 12 made of a cured ultraviolet curable resin was formed on the base film 11.

Next, as shown in FIG. 6A, an Al vapor deposition film 13 a having a thickness of about 200 Å was formed on the PET film having the concavo-convex pattern by a resistance heating vacuum vapor deposition method. The light transmittance of the vapor-deposited PET film at this time is 50%.
Is. However, since the surface of the PET film has a concavo-convex shape, the vapor-deposited film is not uniformly formed on the entire surface, and a vapor-deposited film having different thicknesses is formed on the convex and concave side surfaces. That is, the thickness of the vapor deposition film formed on the convex portion and the side surface varies depending on the height of the convex shape and the inclination angle of the side surface. As described above, the fact that the thickness of the vapor deposition film formed on the uneven surface is different is that when the vapor deposition film is transferred to the transfer target, it rather complicates the reflected light from the vapor deposition film. This will enhance the design effect.

A gravure printing method was used to apply a glitter ink (“GE-HS” manufactured by Showa Ink Kogyo Co., Ltd.) to the aluminum vapor-deposited film having an uneven shape obtained above, and the concave portion with an uneven pattern was brilliantly coated. 6B, the transfer foil 1 was produced by filling the film with a luminescent resin and forming a glittering resin layer 14 having a thickness of 30 μm in a dry state as shown in FIG. 6B. The glitter ink is obtained by adding 10% by weight of a pearl pigment to a binder made of a resin composed of an acrylic resin and a vinyl chloride-vinyl acetate resin so that the solid content is 30% by weight.

As shown in FIG. 7A, the acrylic-styrene resin 9 is formed on the surface of the transparent glass plate 19 having a thickness of 5 mm.
A glass primer composed of 4.5% by weight, 0.5% by weight of a cyan coupling agent, and 5% by weight of polyisocyanate is applied and then heat-cured at 110 ° C. for 8 minutes to form a primer layer 18 having a thickness of 8 μm. did. Next, FIG.
As shown in (b), the glass plate 19 on which the primer layer 18 is formed is heated to 60 ° C., the glitter resin layer 14 of the transfer foil 1 is superposed on the primer surface, and the roll temperature 200
Roll transfer under conditions of ℃ and speed 2m / s, then
As shown in FIG. 7C, the substrate film was peeled off and the transfer layer was transferred to the glass plate.

Further, on the transfer layer, a glass primer containing 10% by weight of titanium oxide added was applied and baked at 160 ° C. for 2 minutes to form a concealing layer 20. Such decorative glass 3 was produced. Since the decorative glass obtained as described above has a three-dimensional effect and is semitransparent, it can be used as a partition. In addition, since it can be easily cut with a glass cutter, it has better workability and improved work efficiency than film laminated glass.

Example 2 An uneven pattern was formed on a PET film in the same manner as in Example 1. 8 (a) on the uneven pattern forming film obtained above.
As shown in FIG. 3, a SiO ₂ vapor deposition film 13b having a thickness of about 500 Å was formed by the electron beam heating vacuum vapor deposition method, and an aluminum vapor deposition film 13a having a thickness of about 200 Å was formed thereon by a vacuum vapor deposition method. The light transmittance of this film was 50%.

On the PET film having an uneven pattern provided with the vapor deposition film obtained above, the glitter resin layer 14 was formed with the glitter ink in the same manner as in Example 1. Further, as shown in FIG. 8 (a), an ink composed of an acrylic resin and a vinyl chloride-vinyl acetate resin having a glass transition temperature (Tg) of 60 ° C. is formed on the glitter resin layer 14 (Showa Ink Industry Co., Ltd. ) "GE-IN"), the plate depth is 100 μm
Gravure printing was performed using the gravure plate to form a pattern 16 and an adhesive layer 17, and thus a transfer foil 2 having an adhesive layer was produced.

Using the transfer foil obtained as described above, it was transferred to a PS plate under the conditions of 200 ° C. and a transfer speed of 3 m / s in the same manner as in Example 1, and as shown in FIG. Decorative board 4 was produced. Further, the decorative board thus obtained was excellent in moldability, and it was possible to obtain a molded article having a three-dimensional effect and excellent in design as in Example 1.

Comparative Example 1 In the same manner as in Example 1, an uneven pattern was formed on the PET film. As shown in FIG. 9 (a), an aluminum vapor deposition film 13 a having a thickness of about 500 Å was formed on the irregular surface of the PET film having the irregular pattern obtained above by a vacuum vapor deposition method. The light transmittance of this film was 6 to 7%. On the vapor-deposited PET film having the uneven pattern obtained above, a glitter ink (“GE-H” manufactured by Showa Ink Industry Co., Ltd.)
S ”) in the same manner as in Example 2, using the glitter resin layer 14
Is formed, and further, as shown in FIG.
The pattern 16 and the adhesive layer 17 were formed to produce the transfer foil 2 having the adhesive layer. Using the transfer foil obtained above, a PS plate at 200 ° C.,
Under the condition of a transfer speed of 3 m / s, transfer was performed in the same manner as in Example 1 to fabricate a decorative plate 4 as shown in FIG. 9 (b).
In the decorative board obtained as described above, the aluminum vapor-deposited film formed on the concavo-convex pattern surface was as thick as 500Å, so the pattern could not be seen through the vapor-deposited film, and the decorative board had a defect.

Comparative Example 2 An uneven pattern was formed on a PET film in the same manner as in Example 1. The titanium chelating agent was diluted with xylene on the uneven surface of the uneven pattern forming film obtained above to obtain 10% by weight.
A solution was applied to form a release layer 31 as shown in FIG. Next, as shown in FIG. 10 (a), a peeling layer 32 and a pattern 16 are formed on the film using an ink mainly composed of polymethylmethacrylate (PMMA), and then an acrylic-styrene copolymer is formed. The transfer foil 2 was manufactured by forming the adhesive layer 17 using a resin made of. The transfer foil 2 obtained above was transferred to a PS plate in the same manner as in Comparative Example 1 to produce a decorative plate 4 as shown in FIG. 9 (b). The decorative plate obtained as described above did not have a semi-transparent aluminum vapor-deposited film on the concavo-convex pattern surface, so that the decorative plate had a poor three-dimensional effect.

[0041]

According to the present invention, a concavo-convex pattern is formed on a base sheet, and a semi-transparent thin film layer such as an aluminum vapor deposition film is formed on the concavo-convex pattern surface, and the transmittance of the thin film layer is 10-9.
By setting it to 0% and forming a glittering resin layer on it, a transfer foil having a three-dimensional effect and an excellent design effect can be obtained, and a transfer foil that can be clearly differentiated from the conventional transfer foil can be obtained. Further, by using the transfer foil of the present invention, it is possible to obtain a transferred material having a three-dimensional effect such as decorative glass, a decorative plate, and a molded article for decoration and having an excellent design effect. Since it is possible to obtain a transfer foil having an excellent design and a three-dimensional effect, which is not seen in the conventional transfer foil, and the transfer layer is translucent, it is possible to produce a decorative glass excellent in partitioning and the like. Furthermore, since the transfer layer is thin and flexible and has excellent processability, the transferred body has excellent processability, and the work efficiency can be improved.
