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 which is easy to peel 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 deposition film is provided 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 film thickness on the water-soluble coating layer, and then a transfer material having a heat-sensitive adhesive layer provided on the entire surface. is there. 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, a metal vapor-deposited layer is provided on the entire surface of a base sheet via a release layer, and an adhesive layer is provided thereon in a pattern. A resin layer was provided, and a 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 immediately after the transfer material of the present invention has been transferred to a transfer object. FIG. 3 is a cross-sectional view showing a state after the transfer material of the present invention has been transferred to a transfer-receiving body and has undergone a water washing step. 1 is a base sheet, 2 is a 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 water-soluble resin layer, 8 is a colored adhesive layer,
Reference numeral 9 denotes a transfer target. 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 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 and becomes the surface of the transfer-receiving body after transfer. The material may be a thermoplastic resin, a thermosetting resin, or a two-component curable resin. In particular, when surface strength is required, an ultraviolet curable resin or an electron beam curable resin may be used. The 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 provided with a release layer 2 to exhibit a metallic luster.
It is formed on the entire surface. The metal deposition layer 5 has an adhesive layer 6
This is a layer that is patterned by a metal 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, and after transfer, the release layer 2 and the metal deposition layer 5 are patterned to form a metal pattern on the transfer object 9. Adhesive layer 6
Is formed by a screen printing method. The thickness of the layer is 0.5 to 15 μm due to problems in transferability and finish appearance.
m is desirable. 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 water-soluble resin layer 7 is formed on a portion of the metal vapor deposition layer 5 that does not overlap with the adhesive layer 6, and after transfer, is dissolved and removed through a water washing step. As the type of the resin used for the water-soluble resin layer 7, any resin that can be made into an ink with a resin such as polyvinyl alcohol or hydroxypropyl cellulose can be used. The printing method of the water-soluble resin layer 7 may be any method such as gravure printing or screen printing. However, the coloring adhesive layer 8 provided next is preferably formed by screen printing. Work becomes easier. The colored adhesive layer 8 is formed on the water-soluble resin layer 7. After the transfer, the colored adhesive layer 8 is peeled off at the interface with the water-soluble resin layer 7 to form a print pattern on the transfer object 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 colored layer 3 may be provided between the 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. When two colors of gold and silver are required, a yellow colored layer 3 is provided on a portion requiring gold color, and the colored layer 3 is not provided on a portion requiring silver color.
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. 2, the part where the adhesive layer 6 or the colored adhesive layer 8 is present is peeled off at the interface between the base sheet 1 and the peeling layer 2, and the peeling layer 2 of the part of the adhesive layer 6 is removed.・ Metal deposition layer 5 ・ Adhesive layer 6 or colored adhesive layer 8
The release layer 2, the metal deposition layer 5, and the water-soluble resin layer 7 are bonded to the surface of the transfer object 9. This is because the adhesion strength between the base sheet 1 and the release layer 2 is lower than the density 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. Next, the transferred object 9 is washed with water. As a method of washing with water, various means such as immersion in water or warm water, shower washing with water or warm water, and ultrasonic washing in water or warm water can be employed. The water-soluble resin layer 7 is dissolved by the water and is removed together with the release layer 2 and the metal deposition layer 5 formed on the water-soluble resin layer 7. Water-soluble resin layer 7
If the dissolution and removal are insufficient, mechanical removal, such as wiping with a cloth after washing with water or scraping with a fine brush, may be performed. In this way, only the colored adhesive layer 8 adheres to the surface of the transfer-receiving body 9 to form a print pattern.

Further thereon, aluminum was deposited by an ordinary deposition method using a high-frequency heating method to provide a metal deposition layer having a thickness of 50 nm. As the adhesive layer, a melamine-epoxy thermosetting resin was used, and an adhesive layer having a thickness of 4 μm was provided in a pattern by screen printing. Hydroxypropylcellulose was used as a water-soluble resin layer, and was provided in a portion not overlapping with the adhesive layer so as to have a thickness of 2 μm by a screen printing method. Finally, using a black ink of the same resin as the adhesive layer, letters were printed on the water-soluble resin layer with a thickness of 2 μm to obtain a transfer material. Composition 1 (parts by weight) Polymethyl methacrylate having a molecular weight of 20,000, a prepolymer having an acroyl group introduced into a side chain thereof 100 Organic solvent 30 Trimethylolpropane triacrylate 20 Benzoin ethyl ether 5 This transfer material was adhered to a glass bottle, and a base sheet was formed. Was peeled off. Next, the adhesive layer was cured by heating at 180 ° C. for 30 minutes, and at the same time, the adhesive strength to the glass bottle was improved. Next, by washing the bottle in a warm bath also serving as a bottle washing step, the water-soluble resin was washed away, and a colored adhesive layer appeared, whereby a beautiful decorative glass bottle was obtained.
