JPS616267A - Sheet product having metallic gloss and pattern on surface of metallic foil and its production - Google Patents

Abstract

PURPOSE:To produce easily a sheet product having metallic gloss and pattern by printing and coating the design consisting of a thermoplastic resin on the surface of metallic foil, transferrring a metallic film deposited by evaporation on a film onto the surface thereof via a release agent, stripping the film and coating a transparent resin on the surface. CONSTITUTION:The pattern of the thermoplastic resin 2 consisting of a vinyl chloride/vinyl acetate copolymer is printed on the surface of Al foil 1 having about 20mum thickness and gloss. The metallic film 3 deposited by evaporation via the release agent on the film is transferred onto the pattern surface by thermocompression bonding and thereafter only the film is stripped and removed in the part of the release agent. The transparent resin film 4 is finally coated over the entire surface on the printed surface side of the Al foil 1, by which the large-sized or long-sized sheet formed with the pattern having the metallic gloss is easily produced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet product in which a pattern with metallic luster is formed on the surface of metal foil, and a method for manufacturing the same.

Metal foils or metal vapor-deposited films are used as decorative paper, as they have the unique luster of metals and exhibit a beautiful and noble design effect.
It is widely used in various fields as labels, decorative foils, decorative materials, and interior materials.

However, although conventional decorative paper laminated with aluminum foil or wrapping paper coated with aluminum has a unique metallic luster, it is undeniable that it gives a monotonous feeling because it has a single luster. For this reason, for labels and interior materials, hot stamping is performed on metal foil or vapor-deposited film to express the desired design, and in some cases, embossing is also applied, but these hot stamping and embossing processes are rarely used. Currently, the process is performed individually on sheets cut to a predetermined size, and it is not only extremely difficult to perform the above processing on large sheets that exceed the bone size, but also reduces productivity. This leads to high product costs.

The present invention relates to a sheet product in which various designs are formed on the metal foil surface of a roll-wound long sheet as well as a large sheet by a transfer vapor deposition film, and a method for manufacturing the same. By printing a pattern with a thermoplastic resin on one side of the foil, the thermoplastic resin is applied only to the pattern area, and then the vapor-deposited side of the metal-deposited film is bonded by thermocompression to the pattern area using a modeling agent. The film is characterized in that the vapor deposited film on the film is transferred only to the patterned area, and then a transparent synthetic resin is coated.

In the present invention, the thermoplastic resin refers to, for example, vinyl chloride-
Examples include MFHB FES (Toyo Ink), which is a vinyl acetate copolymer, but are not necessarily limited thereto.

The transparent synthetic resin is an ink used in general gravure printing, such as MFOP FES (Toyo Ink).

Example 1 As shown in Figure 1, aluminum foil (1) with a thickness of 20 μm
In the spring, a pattern was printed using MIPIF varnish (manufactured by Toyo Ink), which is a vinyl chloride-vinyl acetate copolymer, and the MIF
A HF face, that is, a pattern film of thermoplastic synthetic resin (2) is formed, and then the vapor-deposited side of the film, on which a release agent has been applied in advance and a metal vapor-deposited film is formed thereon, is thermocompression bonded to the pattern area. After transferring the vapor-deposited film of FILM-HI only to the pattern area, the film is peeled off and the metal vapor-deposited film (3
) was formed, and then the entire printed surface side of the aluminum foil (1) was coated with a K MFOP face (manufactured by Toyo Ink) and covered with a transparent resin film (4) to obtain a sheet product.

FIG. 2 shows an embodiment in which the sheet product is embossed.

Example 2 A pattern was printed on a 100μ thick aluminum foil (1) using a thermoplastic synthetic resin (2), such as MPHS Fes (manufactured by Toyo Ink), in the same manner as in Example 1, and then the pattern portion was printed using a vapor deposited film transfer process. An Aluo vapor deposited film (3) with a thickness of 600 to 600 A is formed only on the top, and the surface of the sheet is printed to express a colored pattern (5). A sheet product whose surface was covered with a transparent resin film (4) was obtained by coating the product with a transparent resin film (4). (Fig. 6 Example 3 After bonding aluminum foil (1) with a thickness of 7 μm and thin paper (6) with a basis weight of 35 g/d with vinyl acetate adhesive (7) K, the same procedure as in Example 1 was carried out. A pattern is printed on the aluminum foil (1) using a thermoplastic synthetic resin (2), and then a vapor deposited film (3) with a thickness of 300 to 600 A is formed thereon by a vapor deposition film transfer process, and then a transparent film is formed. A sheet product was obtained by coating the resin film (4) with a synthetic resin liquid.

After printing the design with the thermoplastic resin (2) on the surface of the metal foil (1) in this way, a transfer vapor deposition film is further thermocompressed to form a vapor deposited film (3) only on the thermoplastic resin (2). If K is formed, the vapor deposited film (3) K is formed on the metal foil (1).
The subtle difference in gloss between the metal foil and the vapor-deposited film creates an interesting and innovative color tone, resulting in a sheet product with an elegant pattern, and because it has a transparent synthetic resin film on its surface, the above-mentioned The pattern created by the vapor deposited film (3) is preserved without peeling, and if it is further embossed, the unique luster of the embossing is added, creating an even more elegant design that reveals subtle differences in gloss between the three types: vapor deposited film, metal foil, and emboss. It becomes a sheet product.

Furthermore, if the surface is printed as in Example 2, it becomes a gorgeous packaging material or decorative material. In addition, if tissue paper (6) or various sheet materials are used as a paste material as in Example B, it becomes a sheet product suitable for decorative surfaces, labels, decorative boards, interior materials, etc., and can be used as packaging materials, interior materials, or for art. It can be widely used in various fields.
