As the release paper 21, it is preferable to use a heat resistant film capable of withstanding heat of about 180 ° C. like a polyester film.

In addition, since the thermosetting material layer 22 constitutes a specific letter or figure, a silk screen plate having a specific letter or figure is placed on the film foil 21 and the thermosetting material is applied to complete the left silkscreen. When the plate is separated, the thermosetting material layer 22 formed of a specific letter or figure is formed. Of course, in addition to this method, the technique of applying the thermosetting material layer 22 made of specific characters or figures on the heat-resistant film release paper 21 is various, so the present invention is not necessarily limited to the above printing method.

The material of the thermosetting material layer 22 may be a material that is mainly flexible, such as silicone rubber, thermosetting resin, or urethane rubber, and is not deformed by heat, but silicone rubber is preferably used.

On the surface of the thermosetting material layer 22, a powdery adhesive strengthening agent is uniformly applied to form the adhesive strengthening layer 23. At this time, as a material of the adhesive strengthening layer 23, metal powder, fiber powder, inorganic or organic primer is used as the attachment means. Preferably, synthetic resins having a particle size of about 0.4 mm, for example polyester resin powders, are used. Due to the presence of the adhesive reinforcing layer 23, the thermosetting material layer 22 and the thermal adhesive agent 24 to be described later are closely adhered to each other so as not to be separated from each other during thermal pressing.

On the adhesive reinforcing layer 23, a thermal adhesive agent 24 is attached to the surface of the material 25. At this time, the thermoplastic adhesive of synthetic resins is used as the heat adhesive 24, and there is a property that it is fused when heat is applied in a solid state.

In the manufacturing process of the thermal transfer paper according to the present invention, as shown in FIGS. 3A-3C, first, a thermosetting material layer 22 such as silicone rubber or a thermosetting resin is printed and applied onto the heat resistant film release paper 21.

Before the thermosetting material layer 22 is cured, it is important to make the powdery adhesion strengthening agent 23 be uniformly placed thereon to increase the adhesive force. A portion of the adhesive strengthening agent 23 is hardened and fixed in the state of being buried in the thermosetting material layer 22 so that the adhesive strengthening agent 23 is uniformly placed on the upper portion of the thermosetting material layer 22 before curing. It protrudes above the material layer 22.

Then, when the layer of thermosetting material 22 is cured, a thermal adhesive agent 24 is applied to the upper surface thereof to prepare a label thermal transfer paper 20 according to the present invention.

On the other hand, before the thermosetting material layer 22 is cured, nylon powder (eg, polyamide) is applied and thermally dried, and then placed on a material 25 such as cloth or leather, and thermally pressurized. Once melted and penetrated and penetrated into the material 25, the thermosetting material layer 22 may be firmly attached to the material 25.

When the thermal adhesive agent 24 is bonded to the material 25 in this manner, the material 25 is inverted to be positioned at the lower side, and then the heat press 26 is placed on the heat-resistant film release paper 21 positioned at the top and pressurized. . In this case, the heat adhesive 24 is fused by heat of about 150 ° C. generated by the heat press 26, so that the thermosetting material layer 22 is firmly adhered to the material 25.

At this time, the powdery adhesive strengthening agent 23 adhered to the upper portion of the thermosetting material layer 22 serves as a medium for firmly bonding the two sides between the thermal adhesive 24 and the thermosetting material layer 22 to increase the adhesive strength as much as possible. Since it is possible to give, it is possible to completely solve the conventional problems, such as the adhesive strength is significantly weakened by the oil contained in the thermosetting material layer in the prior art.

Then, the heat press 26 is removed and the heat-resistant film release paper 21 attached to the thermosetting material layer 22 is peeled off to form a label 1 of thermosetting material made of specific letters or figures on the material 25. will be.

Therefore, the present invention is obtained by molding a thermosetting material (material) using an intermediate medium and applying a thermoplastic adhesive to the next side of the intermediate material, even if the material is applied to the upper surface of the thermosetting material layer. Since it is strong against heat and does not perform molecular activity in a heated state, only thermoplastic adhesive is dissolved in heat and adhered to the material.

With reference to the accompanying drawings, a thermal transfer paper for a label and a method of manufacturing the same according to another embodiment of the present invention will be described.

On the release paper 31 is applied a heat adhesive 34 which is attached to the surface of the material 35. In this case, a thermoplastic adhesive of synthetic resin is used as the heat adhesive 34, and has a characteristic of being fused when heat is applied in a solid state.

On the surface of the thermal adhesive layer 34, a powdery adhesive enhancer is uniformly applied to form an adhesive enhancer layer 33. At this time, as the material of the adhesive strengthening layer 33, metal powder, fiber powder, inorganic or organic primer is used as the attachment means. Preferably, synthetic resins having a particle size of about 0.4 mm, for example polyester resin powders, are used. Due to the presence of the adhesive strengthening layer 33, the thermosetting material layer 32 and the thermal adhesive layer 34, which will be described later during thermal pressing, are closely adhered to each other so that they do not fall apart.

At this time, the heat adhesive 34 is fused by heat of about 150 ° C. generated by the heat press 36, so that the thermosetting material layer 32 is firmly adhered to the material 35.

At this time, the powdered adhesive reinforcing agent 33 fixed to the lower portion of the thermosetting material layer 32 serves as a medium for firmly bonding both sides between the heat adhesive 34 and the thermosetting material layer 32 to increase the adhesive strength to the maximum. Since it is possible to give, it is possible to completely solve the conventional problems, such as the adhesive strength is significantly weakened by the oil contained in the thermosetting material layer in the prior art.
