The transfer printing method is a widely used printing technique for forming designs on objects made of various shapes and materials. Conventionally, the so-called heat-pressure transfer method has been mainly used because the degree of adhesion of the transferred design is insufficient in the so-called pressure transfer method in which a pattern is transferred by simply pressing a transfer material against a transfer target. In this method, a transfer sheet with an adhesive layer made of heat-sensitive adhesive is placed on the surface of the object to be transferred so that the adhesive layer is in contact with the transfer sheet, and heated from the base sheet side using a heating roll, etc., and the adhesive is This is a method in which the layer is adhered to a transfer target with adhesive properties, and because it can be easily transferred, it is suitable for mass production and is often adopted. However, this method has the following drawbacks. That is, (1) it takes time to heat from the base sheet side and impart adhesiveness to the adhesive layer. (2) Since the heating also extends to the object to be transferred, there is a drawback that it cannot be applied to non-heat-resistant substrates that are easily deformed by heat, such as plastic molded products.

First, the transfer material according to the present invention is composed of a releasable base sheet, a pattern layer, and an adhesive layer. The base sheet having releasability is made of polyethylene terephthalate film, polypropylene film, polyethylene film, nylon, etc., on which a layer of acrylic, polyolefin resin, vinyl chloride, vinyl acetate, etc. is formed and then subjected to mold release treatment. As a forming means, for example, a gravure coating method or a roll coating method is used. The layer may be peeled off from the transferred pattern after the transfer, or may remain on the transferred pattern even after the layer is peeled off. Furthermore, if necessary, the back surface of the base sheet may also be subjected to mold release treatment.

An adhesive layer is formed on the pattern layer. The adhesive layer is formed by a gravure coating method, a roll coating method, etc. using a composition comprising a prepolymer or oligomer having an epoxy group, an allyldiazonium catalyst, a thermoplastic resin, and an organic solvent. Examples of prepolymers or oligomers having epoxy groups include compositions in which an epoxy compound is subjected to ring-opening polymerization using a photoinitiator that is a compound that generates a Lewis acid when decomposed by light. Further, as the thermoplastic resin, acrylic, vinyl chloride, etc. are used. Organic solvents include trol, ethyl acetate,
Examples include methyl ethyl ketone. Further, in the transfer material according to the present invention, the pattern layer and the adhesive layer may be integrally formed. In this case, the transfer material is configured as follows. That is, a pattern layer is provided on a base sheet having removability similar to that described above, and a pattern is formed by using a composition consisting of a prepolymer or oligomer having an epoxy group, an allyldiazonium catalyst, a thermoplastic resin, and an organic solvent as a binder. There are transfer materials in which the layer and the adhesive layer are integral.

First, the adhesive layer side of the transfer material is irradiated with ultraviolet rays or electron beams. By this irradiation treatment, the allyldiazonium catalyst in the adhesive layer is decomposed, producing a Lewis acid and polymerizing the epoxy group.
Immediately after irradiation, preferably within 10 seconds, the transfer material is used to perform pressure transfer onto the object to be transferred. Since the adhesive layer has a certain degree of adhesive force due to its composition, it is transferred to the surface of the object to be transferred together with the pattern layer. By allowing the image to stand after being transferred under pressure, the polymerization reaction proceeds, and the formation of a three-dimensional crosslinked structure allows the formation of a patterned film to have a large cohesive force. the result,
Since the design has strong adhesion, a solid transferred design can be obtained.

Since the present invention provides a transfer material and a transfer method as described above, by applying the present invention, a solid pattern can be transferred by ultraviolet irradiation or electron beam irradiation without the need for heating. Therefore, it can be transferred very quickly, and it can also be transferred to non-heat resistant substrates such as plastic molded products without damaging the surface of the substrate. Furthermore, since no heating is required, it generally allows for lower costs than thermal transfer methods.
