Description

[Detailed Description of the Invention] (Industrial field of application) The present invention makes it possible to reveal a pattern on a resin layer by heating, and also to provide both layers so that the resin layer and the pattern layer can be transferred at the same time. The present invention relates to a transfer paper provided on a mount.

(Prior Art) A resin capable of dyeing a sublimable dye is attached to the surface of a transferred material, a pattern formed by an ink containing a sublimable dye is applied to the resin, and the pattern is transferred to the resin by heating. Then, it is performed that the transferred material has a durable pattern. However, there is no transfer paper in which a resin layer capable of dyeing a sublimable dye and a pattern layer formed of an ink containing a sublimable dye are provided on the transfer paper, and the resin layer and the pattern layer can be simultaneously transferred.

(Problems to be solved by the invention) When a resin is pasted on a transfer target material and a sublimation dye is transferred to it by applying a pattern as in the past, the resin film provides good abrasion resistance and durability of the pattern. However, it is not only necessary to operate the positioning separately for each of the application of resin and the application of the pattern, but it is also necessary to separately prepare the resin and the mount on which the pattern is printed. Therefore, if the heat treatment is included, the operation is performed three times and the work becomes troublesome, and there is a problem that the technology of the bending angle cannot be developed unless this defect is improved.

(Means for Solving the Problems) The present invention aims to enable the transfer operation of the sublimable dye to be simplified by simultaneously transferring the resin layer and the picture layer onto the transfer target by one transfer paper. And a resin layer enabling dyeing of a sublimable dye and a pattern layer formed by an ink containing a sublimable dye are bonded to each other, and the resin layer and the pattern layer are simultaneously transferred. A transfer paper capable of dyeing a sublimable dye onto a resin layer that enables dyeing of the dye by heating after or simultaneously with transfer, so that transfer including heat treatment may be performed twice or once. There is.

(Example) The printing used in the present invention is prepared by mixing a sublimable dye with a resin that enables transfer dyeing of a pattern such as a printed matter using a sublimable dye by heat treatment. Although it is an ink, such a resin film material and a sublimation dye are already developed and used, and are known to those skilled in the art, and therefore description of the product name, amount used, etc. is omitted.

FIG. 1 exemplifies a transfer paper which can be transferred by a water slide which is one of known transfer means, and is sublimated on a water-soluble paste layer (2) such as dextrin provided on a water-absorbent mount (1). A resin layer (3) that adsorbs the heated sublimation gas of the organic dye to enable the dye to be dyed, and a pattern layer (4) bonded to the upper surface of the resin layer (3) are provided to protect the pattern on the pattern layer (4). Overcoat layer (5) is provided.

The pattern layer (4) uses a printing ink prepared by kneading a sublimable dye, and the resin layer also uses an ink form having good spreadability by mixing a solvent, and the resin layer (3), The pattern layer (4) and the overcoat layer (5) are sequentially applied by screen printing. Resin layer (3) is 20 ~
The thickness is 30 μ, the pattern layer (4) is 15 to 20 μ, and the overcoat layer (5) is about 10 μ.

Fig. 1 shows the soluble paste layer (2) when transferring to the transferred material.
Adhesion is caused by a part of the paste component remaining in the resin layer (3) and the self-adhesiveness of the resin layer (3).
As shown in FIG. 2, an adhesive layer (3a) made of hot melt is provided on the glue layer (2), and a resin layer (3), a pattern layer (4) and an overcoat layer are provided on the layer (3a). It is also possible to adopt an embodiment in which (5) is sequentially provided.

FIG. 3 exemplifies a transfer paper to which heat transfer is applied, and a release layer (12) made of wax or the like which is melted by heating is formed on a base paper (11) having no water absorption property, and the release layer (12) is formed thereon. A pattern layer (13) is formed by using the same printing ink as that for forming the pattern layer (4), and a resin layer (14) made of the same resin material as the resin layer (3) of FIG. 1 is further formed thereon. And the resin layer (1
4) Provide a hot melt layer (15) on top.

FIG. 4 exemplifies a transfer paper for pressure-sensitive transfer, in which the same pattern layer (22) as the pattern layer (4) of FIG. ) Is formed and the first on it
The same resin layer (23) as the resin layer (3) shown in the figure is provided, the pressure sensitive adhesive layer (24) is provided on the resin layer (23), and the adhesive layer (2
4) is covered with peelable paper. Since the resin layer (23) has adhesiveness due to pressure sensitivity, it is not always necessary to provide the adhesive layer (24). In that case, the adhesive layer (24) should be provided on the resin layer (23). Stack the slip sheets.

(Effect of the Invention) To explain the transfer operation method using the transfer paper of the embodiment shown in FIG. 1, the mount paper (1) is wetted with water, dilute alcohol or the like to melt the soluble paste layer (2), As shown in FIG. 5, the upper part of the resin layer (3) is transferred to a predetermined position of the transferred material “a” by a known water slide method and pressed, and then the overcoat layer (5) is removed after natural drying. 220 ℃ / in a heating furnace
Heat for 90 seconds. Then, most of the sublimable dye in the pattern layer (4) is transferred to the resin layer (3), and a pattern which is not easily worn away is produced in the resin layer (3) as shown in FIG.
Since the pattern layer (4) becomes an ink base layer in which some sublimable dye remains or does not remain, it is washed with a solvent such as ethanol and dried. As the above-mentioned solvent, a solvent that does not damage the resin layer (3) held by transferring the sublimable dye is selected.

After performing the above-mentioned treatment, drying is performed to volatilize the solvent to complete the process.

The same applies to the transfer paper of the embodiment shown in FIG.

The transfer papers of the examples of FIGS. 3 and 4 transfer the respective resin layers by thermal transfer and pressure-sensitive transfer, and the processing after the transfer is in accordance with the above. In the case of thermal transfer, pressure heating transfer and transfer of the sublimable dye contained in the pattern layer (13) to the resin layer (14) can be performed at the same time.

As described above, the transfer paper of the present invention has a resin layer (3) that enables dyeing with a sublimable dye,
(14) and (23), and the pattern layers (4), (13) and (22) formed by the ink containing the sublimable dye, the mount (1),
(11), a heat treatment which is provided on (21) by bonding, and transfers the resin and the pattern layer in a bonded state, and transfers the sublimable dye of the pattern layer to the resin layer after or simultaneously with the transfer. The sublimable dye can be transferred to the resin layer in the correct position in two or one step, and the residual resin layer can show the abrasion-resistant pattern. It has the effect that it can be easily applied with only one sheet of transfer paper.
