2. Description of the Related Art Conventionally, as a method of applying a pattern to a material such as synthetic resin, glass, ceramics, metal, etc., a method of directly printing on the material or adhering a paper, a synthetic resin film or the like with the pattern to the material There is a laminating method. Furthermore, a receiving layer of synthetic resin that can be dyed with a sublimable dye is formed on the surface of the material, and a desired pattern is formed on the base sheet of paper, synthetic paper, synthetic film, etc. with an ink containing a sublimable dye as a main component. To create a transfer paper, superimpose this transfer paper on the material to be transferred, and press it with a heat roll, or heat it with a heat press having a pressurizing mold that matches the outer shape of the material to be transferred. There is a transfer printing method in which a sublimation dye is sublimated by applying pressure to form a pattern on a transfer target material.

[0003]

However, although the above methods and methods have the advantage that they can be easily transferred to a material having an arbitrary shape, they have the drawback of poor durability. In addition, while the above method is excellent in durability, when the material to be transferred has a three-dimensional shape and its outer shape is different, a pressurizing mold is required for each material to be transferred, and when the number of materials to be transferred is small. Had a problem that the cost was high. An object of the present invention is to provide a pattern transfer method capable of easily transferring a clear pattern to an object to be transferred of any shape at a relatively low cost even in a small lot, and having excellent pattern durability.

[0004]

In order to achieve the above object, as shown in FIG. 1, the pattern transfer method of the present invention has an adhesive property on the surface of a hard transfer body 10 to which the transfer body 10 is adhered. A sublimable colorant that can be fixed to the sheet 12 on the surface of the base sheet 12 by applying a synthetic resin to a thickness of 0.1 μm to 100 μm and drying it to form the receiving layer 11 (see a partially enlarged view of FIG. 1). A base sheet 1 is formed by printing a picture 13 composed of characters or patterns or a combination thereof with a composition containing as a main component.
2 is fixed to the surface of the transferred material 10 so that the printed surface of the pattern 13 is in contact, the transferred material 10 to which the base material sheet 12 is fixed is covered with the shrinkable film 14, and the transferred material covered with this shrinkable film 14 The body 10 is heated at a temperature higher than the sublimation temperature of the colorant and the same as or higher than the shrinking temperature of the film 14 to sublimate the colorant and shrink the film 14, thereby transferring the transfer target 10 to the substrate sheet 12. Also, the shrinkable film 14 is peeled off to transfer the pattern 13 to the transfer target 10.

The present invention will be described in detail below. The hard transferred material of the present invention is synthetic resin, inorganic glass, glass such as organic glass, tableware, decorators, tiles, ceramics including porcelain such as European porcelain, Shimizu ware and Seto ware, metal, wood. The shape is not limited to a sheet-like object, but a block-like object, a molded article with irregularities,
It may be a container or a processed product. The synthetic resin that constitutes the transferred material and the synthetic resin that is applied to the surface of the transferred material to form the receiving layer are selected from the group of thermoplastic resins, thermosetting resins, ultraviolet curable resins, and electron beam curable resins. One or two or more kinds of synthetic resins are used. The synthetic resin forming the receptive layer is a resin that has adhesiveness to the transferred material.

Examples of this thermoplastic resin include vinyl acetate, polyvinyl alcohol, polyvinyl acetal, polyvinyl ether, polyvinyl chloride, polyvinylidene chloride, acrylic, polyamide, polyurethane, polyimide, polystyrene, polycarbonate, saturated polyester, alkyd, and polyethylene. Etc. In addition, if thermosetting resin is illustrated, phenol resin, urea resin,
Examples thereof include melamine resin, alkyd resin, melamine / alkyd resin, unsaturated polyester resin, acrylic resin, epoxy resin and silicone resin. The above resins can be used alone or in a mixture. Examples of the ultraviolet curable resin and the electron beam curable resin include acrylic acrylate, urethane acrylate, epoxy acrylate, and unsaturated polyester resin.

Coating on the surface of the transfer-receiving member is from 0.1 μm to
It is performed with a thickness of 100 μm. If it is less than 0.1 μm, the fixing power of the coloring material becomes poor, and if it exceeds 100 μm, it may peel off. This coating method includes various coating methods such as spray coating, roller coating, flow coating, spin coating, dip coating and brush coating. The applied synthetic resin is dried to form a receiving layer. This drying is performed at room temperature to 200 ° C. under atmospheric pressure depending on the coating thickness, the type of synthetic resin, and the like.

The base sheet of the present invention includes high-quality paper, medium-quality paper,
Examples include art paper, coated paper, synthetic paper and recycled paper.
The thickness of this substrate sheet is preferably 5 μm to 500 μm, more preferably 30 μm to 200 μm. When the thickness is less than 5 μm, wrinkles are generated on the base material sheet when the shrinkable film shrinks, and transfer unevenness is likely to occur at the time of transfer described below. When the thickness exceeds 500 μm, the thickness of the base material sheet provides heat insulation and the transfer density becomes light. A pattern is printed on the surface of the base sheet with a composition containing a sublimable colorant that can be fixed to the sheet as a main component. This printing method is gravure printing method, letterpress printing method, offset printing method,
Screen printing method, sublimation printer printing method,
Other known methods can be used. The picture is composed of characters or patterns or a combination thereof, and specifically, various pictures such as portraits, landscape pictures, still life pictures, abstract pictures, and geometric pictures, as well as characters, symbols, and figures.

Examples of the shrinkable film used in the present invention include synthetic resin films containing polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride, polyvinylidene chloride, polystyrene and polyamide as main components. The thickness is preferably 5 μm to 100 μm, and more preferably 20 μm to 70 μm. If the thickness is less than 5 μm, the shrinkable film is stretched by heat at the same time as the shrinkable film shrinks, and a predetermined shrinkage is not performed.
The adhesion of the substrate sheet to the transfer target becomes weak and the transfer density becomes light. If it exceeds 100 μm, the thickness of the shrinkable film provides heat insulation and the transfer density becomes light. The shrinkage ratio of the shrinkable film is 5% or more, preferably 10% to 9%.
It is 0%, more preferably 30 to 70%. Shrinkage rate is 5
When it is less than%, the adhesiveness between the base material sheet and the transfer target is lowered, and the transfer density becomes light.

The printing surface of the base sheet and the surface of the transfer-receiving material are fixed with an adhesive tape, an adhesive or the like. The transfer target to which the base sheet is fixed is covered with a shrinkable film and heated to shrink the shrinkable film. The heating at this time needs to be performed at a temperature higher than the sublimation temperature of the colorant and the same as or higher than the shrink temperature of the shrinkable film.
Conditions such as heating temperature and time at this time are the material and shape of the transferred material, the thickness of the base sheet, the printing method, the thickness and shrinkage rate of the shrinkable film, the type or thickness of the synthetic resin as the receiving layer. The heating is 100 ° C to 2
It is performed in the range of 30 ° C. for 0.5 to 10 minutes.
Examples of heating methods include household ovens, microwave ovens, industrial ovens and dryers. After this heating,
By peeling the base sheet and the shrinkable film,
The pattern on the base sheet is transferred to the transfer target.

[0011]

As shown in FIG. 1, when the printing surface of the base material sheet 12 is fixed to the surface of the transferred material 10 and heated under predetermined conditions, the shrinkable film 14 shrinks and the colorant sublimes. Due to the adhesion of the shrinkable film 14 to the transferred material 10 and the sublimation of the colorant, the pattern 1 of the base sheet 12 is formed.
3 is transferred to the transferred body 10.

[0012]

As described above, according to the present invention, the shrinkage pressure of the shrinkable film is used to bring the substrate sheet into close contact with the transferred material by heating. It is not necessary to use the mold of
A clear pattern can be easily transferred to a transfer target made of any material such as glass, ceramics, metal and wood at a relatively low cost even in a small lot. Further, the transfer method of the present invention is a method of directly printing a pattern on a transfer target, or a laminating method of adhering a paper on which a pattern is applied, a synthetic resin film or the like to the transfer target. It has an effect of excellent fastness.
