Abstract

(57) [Summary] [Purpose] To prevent unnecessary parts such as photoelectric cell marks that do not need to be transferred after transfer processing from occurring, and to prevent the generation of dirt and dust. [Structure] A release layer 2, a pattern layer 3, and a heat-sealing layer 4 are provided on one side of the base material layer 1, and a pattern of a transfer-unnecessary portion 5 is provided on the other side of the base material layer 1 to form an adhesive property with the base material layer 1. Print with the ink you have. Since the transfer-unnecessary portion 5 is firmly adhered to the base material layer 1, even if wrinkles are generated in the base material layer 1 due to heat during transfer, it does not easily come off, and the base material layer 1 after winding is rolled up. Sometimes it doesn't fall off.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a transfer foil used for thermal transfer printing.

[0002]

[Prior Art]

 Conventionally, thermal transfer printing has been widely used as one of the methods for printing a pattern on an object to be printed such as plastic, glass, metal, and ceramics, which is difficult to print directly. That is, using a transfer foil having a pattern layer provided on one side of a base material layer such as a polyester film via a release layer, and a heat seal layer provided on the pattern layer, the transfer foil is attached to a substrate to be printed, After applying a heat pressure to form a pattern on the material to be printed, the base material layer is peeled off. Then, usually, a hot stamping machine intermittently unwinds the rolled transfer foil to position it with respect to the printing medium so that the transfer is continuously performed. In this case, a pattern such as a phototube mark is printed on the transfer foil separately from the pattern, and the positioning is performed by this.

[0003]

[Problems to be solved by the device]

 However, in the conventional transfer foil, the photoelectric tube mark and the pattern are printed at the same time, and the pattern of the transfer unnecessary portion such as the photoelectric tube mark is also provided on the peeling layer like the pattern layer. If wrinkles are generated on the base material layer due to heat during transfer, this unnecessary transfer part will easily fall off, and when the base material layer is rolled up after transfer processing, it will fall off from the base material layer and cause dirt and dust. There was a problem.

[0006] Therefore, it is conceivable that the release layer is part-coated so that the printed portion of the transfer unnecessary portion is removed and the transfer unnecessary portion is directly printed on the base material layer. However, the release layer is almost colorless and transparent, and the transfer unnecessary portion is not necessary. There is a situation that it is difficult to match with the department.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a transfer foil in which a transfer unnecessary portion such as a photoelectric tube mark does not drop off after transfer processing. ..

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the transfer foil of the present invention is provided with a release layer, a pattern layer, and a heat seal layer on one side of the base material layer, and a transfer unnecessary portion such as a photocell mark on the other side of the base material layer. The above pattern is printed with an ink having adhesiveness to the base material layer.

[0007]

[Action]

 In the transfer foil having the above structure, the pattern of the transfer-unnecessary portion such as the photoelectric tube mark is firmly adhered directly to the base material layer. Therefore, the transfer-unnecessary portion is not easily peeled off even if wrinkles or the like occur in the base material layer due to heat during transfer, and does not fall off when the base material layer is wound after the transfer processing.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing the structure of a transfer foil which is an embodiment of the present invention. In the figure, reference numeral 1 is a polyester film as a base material layer, a release layer 2 is provided on one surface side thereof, a pattern layer 3 is printed on the release layer 2, and the pattern layer 3 is further covered. The heat seal layer 4 is provided. Then, on the other surface side of the base material layer 1, a pattern of the transfer unnecessary portion 5 such as a photoelectric tube mark is printed at a position where it does not overlap with the pattern layer 3.

The pattern printing of the transfer unnecessary portion 5 is performed by a method of reversing the printing material (base material layer) with a turn bar of a gravure printing method, so that the peeling layer 2, the pattern layer 3 and the heat seal on the opposite surface are printed. In-line printing is done at the same time as layer 4. In this case, as the ink used for printing, an ink having adhesiveness to the base material layer 1 is used.

The transfer foil is manufactured in a wound state and is subjected to a known hot stamping machine when transferring to a product. In the hot stamping machine, the transfer foil is intermittently paid out from the winding, and is transferred by being positioned by the pattern of the transfer unnecessary portion 5. Then, the base material layer 1 after the transfer is wound up in a roll shape. Here, since the ink in the transfer unnecessary portion 5 is firmly adhered to the base material layer 1, it does not come off even after the transfer processing.

[0012]

[Effect of the device]

 As described above, in the transfer foil of the present invention, the transfer unnecessary portion such as the photoelectric tube mark is provided on the surface of the base material layer opposite to the transfer side by printing the ink having the adhesive property with the base material layer. Unlike the conventional transfer foil in which the transfer-unnecessary part is provided on the release layer, the ink layer of the pattern of the transfer-unnecessary part does not fall off when the base material layer is rolled up after the transfer processing, so that it does not become dirty or dusty. It is possible to prevent the generation of foil scraps.
