Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a transfer material capable of simultaneously forming only a metal pattern and a print pattern.

[Prior art and its problems]

Conventionally, as a transfer material for simultaneously forming a metal pattern and a print pattern, there is Japanese Utility Model Publication No. 53-21124.
This is a method in which a transparent release layer that is easily peeled off from the film substrate is provided on one side of the film substrate, a coloring layer and a water-soluble coating layer are partially provided on an arbitrary pattern, and then a metal-deposited film is formed on the entire surface After applying the layer, the water-soluble coating layer is dissolved and removed by washing with water to remove the metal deposition layer on the water-soluble coating layer, and then the transfer material is provided with a heat-sensitive adhesive layer on the entire surface. . When a transfer material having such a layer configuration is transferred to a transfer target, a transparent layer including an adhesive layer and a release layer is also transferred to a portion other than the metal pattern and the print pattern. On the other hand, in order to form a metal pattern and a printed pattern without transferring a transparent layer, a transfer material having an adhesive layer formed in a pattern is used. However, since the metal pattern and the print pattern are not formed on the same transfer material, the metal pattern or the print pattern is expressed in separate transfer steps. An object of the present invention is to solve the above-mentioned problems and to provide a transfer material capable of simultaneously forming only a metal pattern and a print pattern.

[Means for Solving the Problems]

The present invention is configured as follows to achieve the above object. That is, in the transfer material of the present invention, the metal deposition layer is provided on the entire surface of the base sheet via the first release layer, and the adhesive layer is provided thereon in a pattern. 2 The release layer was provided, and the colored adhesive layer was provided thereon in a pattern. The present invention will be described in more detail with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the transfer material of the present invention. FIG. 2 is a cross-sectional view showing a state in which the transfer material of the present invention has been transferred to a transfer target. 1 is a base sheet, 2 is a first release layer, 3 is a colored layer, 4 is an anchor layer before vapor deposition, 5 is a metal vapor deposited layer, 6 is an adhesive layer, 7 is a second release layer, 8 is a colored adhesive layer, 9 is Each of the transferees is shown. As the base sheet 1, a sheet used for a normal transfer material base sheet, such as a plastic film such as polyethylene terephthalate, polypropylene, polyethylene, nylon, or cellophane, or a composite film of these and paper is used. Further, in order to improve the releasability, the surface of the base sheet 1 may be subjected to a release treatment. The first release layer 2 is provided on the entire surface of the base sheet 1, and is a layer that is separated from the base sheet 1 after transfer and becomes the surface of the transfer-receiving body. The material may be a thermoplastic resin, a thermosetting resin, or a two-component resin. In particular, when surface strength is required, an ultraviolet curable resin or an electron beam curable resin may be used. The first release layer 2 of such a material is formed on the base sheet 1 by a normal printing method such as a roll coating method, a gravure printing method, and a screen printing method. The metal deposition layer 5 is formed on the entire surface of the first release layer 2 to provide a metallic luster. The metal deposition layer 5 is a layer that is patterned by the adhesive layer 6 to express a metal pattern. The metal deposition layer 5 is formed by a vacuum deposition method, a sputtering method, an ion plating method, or the like, and a metal such as aluminum, nickel, or chromium can be used as a deposition metal. The adhesive layer 6 is formed in a pattern on the metal deposition layer 5. After the transfer, the first release layer 2 and the metal deposition layer 5 are patterned to form a metal pattern on the transfer object 9. The adhesive layer 6 is formed by a screen printing method. The layer thickness is 0.5 to 15 due to problems in transferability and finish appearance.
It is desirable to set it to μm. When an ultraviolet curable resin or an electron beam curable resin is used as the type of the resin used for the adhesive layer 6, it is possible to finish the resin with a very excellent adhesive strength by irradiating ultraviolet rays or an electron beam after the transfer. . When a thermosetting resin such as melamine or epoxy is used, a necessary strength can be obtained by performing a heat treatment after the transfer. The second release layer 7 is formed on a portion of the metal vapor deposition layer 5 that does not overlap with the adhesive layer 6, peels off at the interface with the colored adhesive layer 8 after transfer, and is removed together with the base sheet 1. As the type of the resin used for the second release layer 7, a silicone-based / fluorine-based resin, or a cellulose-based resin such as cellulose acetate / cellulose acetate butyrate or nitrified cotton is used. Any material may be used as long as it can be peeled off at the interface with the adhesive layer 8, and the material is not particularly limited. The printing method of the second release layer 7 may be any method such as gravure printing and screen printing. However, since the coloring adhesive layer 8 to be provided next is preferably formed by screen printing, Work becomes easier. The colored adhesive layer 8 is formed on the second release layer 7, and after transfer, is peeled off at the interface with the second release layer 7 to form a print pattern on the transfer body 9. As the material, the same resin as the adhesive layer 6 is basically used. After the transfer, a print pattern is formed on the surface of the transfer-receiving member. If necessary, a coloring layer 3 may be provided between the first release layer 2 and the metal deposition layer 5. The coloring layer 3 is a layer for coloring the metal pattern, and is provided partially or entirely as necessary. If the metal deposition layer 5 is made of aluminum and gold coloring is required, a yellow colored layer 3 is provided. In the case where two colors of gold and silver are required, a yellow colored layer 3 is provided in a portion requiring gold color,
The colored layer 3 is not provided in a portion requiring silver coloring. By doing so, a metal pattern of two colors of gold and silver can be simultaneously formed. The method for forming the colored layer 3 is not particularly limited. The pre-deposition anchor layer 4 is provided before the metal deposition layer 5 is provided, if necessary, in order to improve the adhesion of the metal deposition layer 5. The pre-deposition anchor layer 4 is a layer to be a support layer of the metal deposition layer 5 and is not particularly limited as long as the metal deposition layer 5 is fixed. For example, a two-component curable urethane resin, a melamine-based or epoxy-based thermosetting resin, or a thermoplastic resin such as a vinyl chloride-vinyl acetate copolymer resin can be used. The transfer object onto which the transfer material of the present invention is transferred is not particularly limited as long as it is a material used for normal transfer processing such as glass or plastic. The transfer method is not particularly limited as long as it is a normal transfer method such as a roll transfer method, an up-down transfer method, or an in-mold transfer method.

[Action]

After the transfer material of the present invention is overlaid on the transfer object 9,
Heat and / or pressurize. Next, when the base sheet is peeled off, as shown in FIG.
The first peeling layer 2, the metal deposition layer 5, and the adhesive layer 6 at the adhesive layer 6 adhere to the surface of the transfer-receiving body 9 to form a metal pattern. This is because the adhesion strength between the base sheet 1 and the first release layer 2 is smaller than the adhesion strength between the other layers. Further, the portion where the second release layer 7 is interposed is separated from the interface between the second release layer 7 and the colored adhesive layer 8, and the colored adhesive layer 8 is adhered to the surface of the transfer-receiving body 9 to form a print pattern. This is because the adhesion strength between the second release layer and the colored adhesive layer 8 is smaller than the adhesion strength between the other layers. In addition, a portion having neither the adhesive layer 6 nor the colored adhesive layer 8 is peeled off together with the base sheet 1 without adhering to the transfer object 9.
