DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 are cross-sectional explanatory views showing the structures of transfer marks according to the first and second inventions, respectively.

FIG. 1 shows a transfer mark according to the first aspect of the present invention. On the surface of film 1,
The release layer 2 that is melted by heating is applied to form a mount. The peeling layer is made of paraffin, wax, or the like, and is formed in a relatively thin predetermined amount.

A monochromatic or polychromatic ink layer 3 is provided on the upper surface of the release layer of the mount. The ink layer 3 is made of a two-liquid reactive synthetic resin such as urethane that causes a so-called cross-linked film formation by causing a chemical reaction at room temperature or by heating. The reaction of the ink layer 3 is further promoted by heating. A synthetic resin such as polyester, acrylic, epoxy or a mixture thereof may be added to the ink layer. It is also possible to add various organic curing accelerators.

Next, the upper surface of the ink layer 3 is coated with an adhesive layer 4 which has not yet been sufficiently hardened and which is softened by hot pressing and adheres to the transferred material. For the adhesive layer, a synthetic resin such as acrylic resin or melamine resin that has good adhesiveness, is strong in film formation, and has various chemical properties is selected.

In order to use the transfer marks according to the present invention thus laminated, the adhesive layer 4 is first placed on the surface of the transfer object, and the heat press is carried out at about 100 ° to 300 ° C. from the mount. Is applied for several seconds to soften the adhesive layer 4 to bring out the adhesive effect and attach it to the surface of the transferred material. Next, the backing sheet is peeled off, but since the peeling layer 2 is melted by hot pressing, it can be peeled off easily. The transfer paper with the backing paper peeled off and the adhesive layer 4 attached to the surface of the transferred material is moved to the heating / baking process to complete the chemical reaction of the ink layer through the adhesive layer 4 by infrared rays or the like to transfer the transferred material. It is what is welded and baked on the surface.

FIG. 2 shows a transfer mark according to the second invention. Between the release layer 22 and the ink layer 24, which are applied to the upper surface of the film 21, a top clear layer 23 formed by applying a two-liquid reactive type transparent resin such as urethane is formed. Usually, after the transfer mark of the first invention is transferred, in order to improve its weather resistance on the upper surface of the ink layer,
Top clear coating is often performed, but in the transfer mark of the second aspect of the invention, the top clear layer is provided in the structure, and the top clear coating after finishing is not necessary. The structure in which the adhesive layer 25 is overprinted on the upper surface of the ink layer 24 is exactly the same as the transfer mark of the first invention.

As described above, the transfer marks shown in both FIGS. 1 and 2 are substantially the same except for the presence or absence of the top clear layer, and a peeling layer is formed on the upper surface of the film, An ink layer for applying a two-component reaction type colored resin is provided on the upper surface, and an adhesive layer made of a thermosetting resin which has not been sufficiently cured is further provided on the ink layer, and the layer is applied to the surface of the transfer target by heat pressing. The main feature is that the adhesive layer and the ink layer are fixed together on the surface of the transferred material and baked by heating after that.

[0013]

EFFECTS OF THE INVENTION Since the heat-fusion-type heat-curable transfer mark according to the present invention is based on the above constitution, a. Compared with the conventional heat fusion type based on thermoplastic resin, the film forming performance is remarkably tough, and its durability, weather resistance, chemical resistance, etc. are remarkably excellent. ． In addition, an adhesive layer having its respective characteristics in its structure,
The ink layer and the transparent top clear layer are capable of fulfilling adhesiveness and other useful functions to each individual and should be highly evaluated as a new transfer mark.
