BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer foil used for heat-sensitive transfer painting, and a pattern having a three-dimensional effect and a gloss change on the surface of a transferred substrate (direction of stripes of adjacent unit patterns) The present invention relates to a transfer foil (hereinafter referred to as a new opal transfer foil) capable of providing a convex pattern formed by combining a plurality of unit patterns so as to be different from each other.

[0002]

2. Description of the Related Art The surface of a transfer-receiving substrate decorated with a conventional transfer foil often lacks a three-dimensional effect and a change in gloss. There are things that caused
The design was not so different from the conventional one.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to provide a pattern having a three-dimensional effect and a rich gloss change on the surface of a transferred substrate. The purpose is to provide a transfer foil.

[0004]

The present invention relates to a transfer foil used for heat-sensitive transfer painting, in which at least a release layer, a release layer and an adhesive layer are sequentially laminated on a base film,
A convex pattern (hereinafter referred to as a new opal pattern) that is composed of a thermosetting resin as a main component in the release layer and is formed by combining a plurality of unit patterns so that the stripes of the unit patterns adjacent to the release layer have different directions. It is a transfer foil provided by embossing.

(Detailed Description) The present invention has found that the above problems can be solved by using a thermosetting resin as a main component as a releasing layer and forming a new opal pattern on the releasing layer by embossing. Is. The reason why the resin is limited to the thermosetting resin is that the mold releasing property is generated by the heat curing of the mold releasing agent at the time of emboss formation, and the heat return of the emboss formation at the time of transfer is prevented.

Further, there is an embodiment in which the following configuration is added to the above basic configuration. (A) A transfer foil having a pattern layer provided between the release layer and the adhesive layer. (B) A transfer foil in which a concealing layer is provided between the release layer or the pattern layer and the adhesive layer.

The present invention will be described in detail with reference to the drawings. Referring to FIG. 1, a release layer (2), a release layer (3) and an adhesive layer (4) are sequentially formed from a base film (1) to form a transfer foil (5).

The base film (1) may be one normally used for transfer foils, and a sheet of polyethylene, polypropylene, polyethylene naphthalate, polyethylene terephthalate or the like having a thickness of about 12 to 50 microns is used.

As the release layer (2), one or more of thermosetting resins such as epoxy resin, melamine resin, acrylic polyol and urethane resin are used, and uncured ones are used.

Vehicles for the release layer (2) include cellulose derivatives, styrene resins, styrene copolymer resins, acrylic resins, methacrylic resins, rosin ester resins, polyvinyl acetate resins, polyvinyl chloride, vinyl chloride / vinyl acetate One kind or a mixture of two or more kinds of coalescing, polyester resin, polyurethane resin, butyral resin, and polyamide resin is used. It is usually transparent, but it may have a transparent color.

The adhesive layer (5) is a cellulose derivative,
One of styrene resin, styrene copolymer resin, acrylic resin, methacrylic resin, rosin ester resin, polyvinyl acetate resin, polyvinyl chloride, vinyl chloride / vinyl acetate copolymer, polyester resin, polyurethane resin, butyral resin, polyamide resin or A mixture of two or more kinds may be used as a vehicle and may further contain a coloring agent and the like.

Further, as shown in FIG. 2, a pattern layer (6) may be provided between the peeling layer (3) and the adhesive layer (4). By synchronizing the pattern layer with the new opal pattern, a more three-dimensional effect can be obtained compared to when the pattern is not synchronized. As the vehicle for the pattern layer (6), a cellulose derivative, styrene resin, styrene copolymer resin, acrylic resin, methacrylic resin, rosin ester resin, polyvinyl acetate resin,
One or a mixture of two or more of polyvinyl chloride, vinyl chloride / vinyl acetate copolymer, polyester resin, polyurethane resin, butyral resin, and polyamide resin is used. In addition, it contains a coloring agent. It is possible to print a gradational pattern by the normal gravure printing method.

Further, as shown in FIG. 3, a concealment layer (7) is provided between the peeling layer (3) and the adhesive layer (4) for concealing the surface color of the transferred substrate and for further enhancing the gloss change. May be provided. The concealment layer is composed of a white ink single layer, a white ink layer / a vapor deposition layer / a white ink layer, and a white ink layer /
Two-layer structure of vapor deposition layer, three-layer structure of white ink layer / black ink layer / white ink layer, two-layer structure of white ink layer / black ink layer, single layer of vapor deposition layer, two-layer structure of vapor deposition layer / white ink layer Is. Vehicles for the white ink layer and the black ink layer include cellulose derivatives, styrene resins, styrene copolymer resins, acrylic resins, methacrylic resins, rosin ester resins, polyvinyl acetate resins, polyvinyl chloride, vinyl chloride / vinyl acetate copolymers, polyesters. A resin, a polyurethane resin, a butyral resin, or a polyamide resin is used alone or as a mixture of two or more kinds. A metal such as aluminum, copper, chromium or tin is used for the vapor deposition layer. When the vapor-deposited layer single layer constitution or the two-layer constitution of the vapor-deposited layer / white ink layer is used, the gloss change can be more emphasized.

[0014]

When the new opal pattern is embossed on the release layer, a surface having a three-dimensional effect and a change in gloss can be attached to the transfer target substrate. Further, by providing the pattern layer, the stereoscopic effect can be further obtained by synchronizing the pattern with the new opal pattern. Further, by using a vapor deposition layer as the concealing layer, it is possible to further emphasize the change in gloss.
