2. Description of the Related Art Conventionally, when obtaining a very small amount of printed matter, a copying machine or a printer for a personal computer is used, but in this case, only a thin paper or a small portion of a plastic film that can pass through the machine is used. Have been. Also, a method using transfer paper is widely used, but in many cases, an image formed on a hot-melt adhesive film is transferred together with the film, and it is not possible to obtain a texture directly printed on a material. Did not. There is also a method in which only the toner component of a dry copying machine is partially transferred.However, the toner of the copying machine has an adhesive property only to papers and some plastics. It was difficult to transfer. In addition, the color of the copy toner is limited to four colors of cyan, magenta, and yellow in addition to black, and it has been difficult to obtain a white or gold image.

[0003]

SUMMARY OF THE INVENTION The present invention is a simple and inexpensive method for transferring color images including white and gold colors to various transfer materials without using an adhesive such as hot melt. The purpose is to transfer and print only the ink components of a hot-melt printer that has better adhesion to various materials than the toner of a dry copier. What you want to do.

[0004]

In order to achieve the above-mentioned object, in the image transfer method of the present invention, a transfer paper having a water-soluble glue laminated on the surface of a paper base material is provided. Then, after printing the ink image on the surface of the transfer paper with a hot-melt ink transfer type printer, an adhesive film coated with a re-peelable adhesive on the ink image surface is polymerized, and is pressed with a spatula or heated by a laminator or the like. Heat-press bonding with a roller. Then, when water is applied using a brush or the like from the back of the paper base, the water-soluble paste is melted, and when the paper base is peeled,
The ink image transfers to the adhesive surface of the adhesive film. After the moisture remaining on the adhesive sheet is sufficiently dried, the ink image surface is polymerized on a transfer material such as a plastic product, and the heated rubber plate or the like is pressed from the surface of the adhesive film to form the ink image. The ink being formed exhibits adhesiveness and adheres to the material to be transferred. After sufficiently cooling the ink, the ink image is transferred from the adhesive surface to the surface of the material to be transferred by peeling the adhesive film to complete the transfer. The reason for using a water-soluble glue instead of using a transfer agent coated with a release agent such as silicon as the transfer paper is that the hot-melt printer has poor printing performance on the release agent coated surface,
This is because there is a high possibility that the ink image is peeled off without being firmly fixed. On the other hand, a water-soluble paste does not have releasability unless it is impregnated with water, and has the advantage of having the same ink adhesion as general printing paper. Also, the second
The reason for using a removable adhesive film as the transfer sheet is that when transferring the ink image from the printed transfer paper, it is only necessary to press with a spatula, and when transferring to the material to be transferred, the film itself is adhered. This is because there is an advantage that the film does not shift and image blurring occurs when the film is firmly adhered to the surface to be transferred by the force and heated and pressed. The means for heating and pressing may be a hot plate such as a household iron, but it is desirable to press through a resilient material such as silicon rubber if possible. In the present embodiment, transfer was efficiently performed using a rotary heater having silicon rubber around it.

And a sheet-shaped paper substrate made of various papers (2)
And a water-soluble glue (3) is laminated on the surface. On the surface of the transfer paper (1), the one shown in FIG. 1 (b) is printed out on the surface of the water-soluble glue (3) by a hot-melt ink transfer type printer to form an ink image (4).
(4) is formed. After that, as shown in FIG. 1 (c), on the surface side of the ink images (4), (4)..., Re-peeling is performed by applying a re-peelable adhesive (6) to a sheet substrate (7). The surface of the removable pressure-sensitive adhesive (6) of the pressure-sensitive adhesive film (5) is polymerized and pressed. Next, as shown in FIG. 4D, water (8) is applied to the transfer paper (1) from the paper base (2) side by using a seal.
Is applied, the water-soluble paste (3) melts. Then, as shown in FIG. 5E, when the paper base material (2) is peeled off, the ink images (4) and (4) are removed from the water-soluble paste (3).
Are transfer-adhered to the removable adhesive (6) side.

Next, as shown in FIG. 1F, the surfaces of the ink images (4) and (4) are superimposed on the surface of the material to be transferred (10) such as a plastic, a metal surface, or a glass plate. Next, the upper surface of the sheet substrate (7) of the re-peelable adhesive film (5) is heated and pressed by a hot plate or the like. Then, figure (g)
As shown in FIG. 5, the ink images (4), (4)... Are separated from the removable adhesive (6) by removing the removable adhesive film (5) from the surface of the transfer-receiving material (10). To complete the transfer, and ink images (4) and (4) on the surface
Is to appear.

[0007]

[Experimental example] As the transfer paper, a water transfer paper for ceramics, in which a water-soluble dextrin is applied to the surface of a paper substrate having water absorbency, is used. Characters were printed on the surface of the transfer paper using a special color white ink using a hot-melt printer “MD5000” manufactured by Alps Electric Co., Ltd. Next, the adhesive surface of the Dainippon Ink and Chemicals removable adhesive film "SOFTAC" was polymerized on the image surface, pressed with a spatula, and then water was applied with a brush from the back of the paper base material. Upon release of the substrate, the ink image was completely transferred onto the adhesive surface. After sufficiently drying the moisture remaining on the adhesive film, the ink image surface is polymerized on a polypropylene film having a thickness of 40 microns, and a rotary rubber roller having a surface temperature of 140 ° C. is applied from the upper surface of the adhesive film, After heating and pressing at a speed of about 1 meter per minute, the adhesive film was peeled off after the ink cooled, and the characters of the white ink were completely transferred onto the polypropylene film. In addition, MD50
In the case of No. 00, it was possible to print out with a color ink or a gold foil, but in each case, as in the case of the white ink, it was possible to transfer completely.

[0008] In addition to the above-mentioned polypropylene film, the material to be transferred may be high quality paper, coated paper, printing surface,
When applied to zelkova material, ABS resin, acrylic resin, vinyl chloride, pottery, glass, and stainless steel, it was possible to transfer an image to each, although there was a difference in ink adhesion strength.

[0009]

As described above, according to the image transfer method of the present invention, it is possible to easily transfer a white or gold image, which has conventionally been difficult to transfer in a small amount, and to various materials other than paper. In addition, since only the ink component is transferred, there is an effect that the same feeling as when directly printing on a material can be obtained. Also, compared with the printing means, there is no need to make a plate, so that there is an effect that even a small quantity can be produced at low cost. Furthermore, there is no need to prepare expensive equipment and facilities, the effect of diverting general-purpose printers that are conventionally used for office use, and the need for advanced technology and skill is eliminated, and any number of people can use and create easily and reliably in a short time. effective.
