  In the first conventional example, when sticking paper or the like, it is transferred onto the paper surface, and the adhesive after transfer is limited to a predetermined tape width and constant in order to achieve reliable adhesion. It has a line shape with a width, and it cannot be formed like a pattern and / or characters and / or figures by the pressure-sensitive adhesive after transfer, and cannot be enjoyed in design and / or visually. There's a problem.

  In the second conventional example, it is printed with UV curable resin ink on the base film, and further has an adhesive layer on the base film. Or although it can enjoy visually, there exists a problem that the effect of sticking articles, such as another paper surface, to the adhesion layer after transfer to a to-be-transferred body cannot be acquired.

  Further, in the third conventional example, when the adhesive transfer sheet or tape is adhered in a straight line or the like, or when the adhesive transfer sheet or tape is adhered over a long distance, the handling property is poor and the adhesive transfer sheet or tape is twisted. There is. Moreover, in order to adhere firmly to a to-be-transferred body, the operation | work which presses by the hand after attaching the said adhesive transfer sheet or tape to a to-be-transferred body is needed.

  Further, in the fourth conventional example, the pressure-sensitive adhesive layer having a dot shape is transferred to the transfer surface, and the pressure-sensitive adhesive after transfer is formed so as to mold a pattern and / or characters and / or figures. It is not designed and is difficult to enjoy in design or visually.

  In view of the above problems, the present invention includes a transfer-type pressure-sensitive adhesive tape formed such that a pressure-sensitive adhesive layer made of an ultraviolet curable pressure-sensitive adhesive molds a pattern and / or characters and / or figures by printing. It is an object of the present invention to provide an automatic winding type film transfer tool characterized by the above.

  In order to solve the above-described problems, a coating film transfer tool of the present invention includes a feeding unit that feeds out a transfer-type pressure-sensitive adhesive tape, a transfer head that presses and transfers the tape against a transfer target, and a post-transfer An automatic winding type film transfer tool having a winding portion for winding a base tape, wherein the transfer type pressure sensitive adhesive tape has a pressure sensitive adhesive layer made of an ultraviolet curable adhesive on the base tape, and A continuous picture pattern and / or letters and / or figures are formed by printing, and pressure-sensitive adhesion having the above-mentioned shape is easily and quickly pressed and transferred to a transfer medium such as a paper surface by the coating film transfer tool. The layer is configured such that the layer is pressed and transferred to the transfer body, and another article can be attached to the transfer body.

  In addition, the transfer-type pressure-sensitive adhesive tape mounted on the coating film transfer tool of the present invention has a pressure-sensitive adhesive layer on the base tape that has a continuous pattern and / or characters and a UV-curable adhesive. A figure is formed and printed by a silk screen printing method so that it can be enjoyed in design or visually.

  In addition, the transfer-type pressure-sensitive adhesive tape mounted on the coating film transfer tool of the present invention has a pressure-sensitive adhesive layer on the base tape that has a continuous pattern and / or characters and a UV-curable adhesive. The thickness of the pressure-sensitive adhesive layer on which the graphic pattern and / or the character and / or graphic formed on the transfer object is formed is required for attaching or joining other articles. Have.

  According to the present invention, the following remarkable effects are achieved.

  Since the transfer-type pressure-sensitive adhesive tape mounted on the coating film transfer tool of the present invention is formed by printing, a clear picture pattern and / or characters and / or figures are formed, and the feeding portion, transfer head The pressure-sensitive adhesive layer is pressure-transferred in a straight line with a uniform concentration and with a quick operation without soiling the hand, since it is provided in an automatic winding type film transfer tool having a winding part. Since the pressure-sensitive adhesive layer after transfer onto the transfer surface is sticky, other articles such as paper can be used after the transfer as in the case of a conventional transfer-type pressure-sensitive adhesive tape. It can be attached to the pressure sensitive adhesive layer.

  Further, the coating film transfer tool comprises an automatic winding type film transfer tool having a feeding part for feeding out the transfer type pressure sensitive adhesive tape, a transfer head, and a winding part for winding the base tape after transfer.

  Also, unlike the technology that uses known adhesives, UV curable adhesives are cured in a very short time at room temperature, so work efficiency is high and they do not show temperature dependence. Since there is less variation in the adhesive force and holding power of the pressure-sensitive adhesive layer made of the agent than in the case of having a drying process, it is possible to clearly express a pattern and / or characters and / or figures such as fine letters, fine lines, photographs, The pressure-sensitive adhesive layer having the above-described shape has sufficient adhesiveness for adhering other articles such as paper.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a coating film transfer tool 1 of the present invention. The coating film transfer tool 1 is divided into a case main body 2 and a cover 10 (not shown), and is coated on one side of a base tape on two support shafts 3 and 4 implanted in the case 1 on the tip side. A feeding roll 6 wound with a transfer-type pressure-sensitive adhesive tape 5 provided with a film and a take-up roll 7 for collecting the used transfer tape are rotatably supported in conjunction with each other, and a pressure transfer unit is provided at the tip. A transfer head 9 provided with 8 is provided such that the pressing transfer portion 7 protrudes outside the case 1, and the case 2 is covered with a cover 10. The transfer-type pressure-sensitive adhesive tape 5 wound around the feeding roll 6 is pulled out, and the coating film of the transfer-type pressure-sensitive adhesive tape 5 is pressed against the transfer target by the pressure transfer unit 8 of the transfer head 9, and transferred. The subsequent base tape is wound up by a winding roll 7.

  FIG. 2 is a schematic cross-sectional view showing a cross-sectional structure of a transfer-type pressure-sensitive adhesive tape provided in the coating film transfer tool according to the embodiment of the present invention. The transfer-type pressure-sensitive adhesive tape shown in FIG. 2 is prepared by first preparing a belt-like substrate 11 wound in a roll shape, and then applying an ultraviolet curable adhesive on the substrate 11 by a silk screen printing method. After printing, the pressure-sensitive adhesive layer 12 is formed so as to mold a plurality of pictures and / or characters and / or figures by curing the pressure-sensitive adhesive by ultraviolet irradiation. In addition, a hardening process should just be performed in accordance with a conventional method using a well-known ultraviolet irradiation apparatus, and conditions etc. are not specifically limited. Curing is usually completed in about 2 to 10 seconds. As described above, since the base material 11 is made of a strip-shaped material wound in a roll shape, the pressure-sensitive adhesive layer 12 is formed and then cut into a predetermined width and length.

  The base material 11 is a film made of a synthetic resin such as polyethylene terephthalate, polypropylene, polycarbonate, polystyrene, polyamide, polyamideimide, polyethylene, polyvinyl chloride, a film-like material such as glassine paper, artificial resin film, paper Japanese paper, or the like. It is composed of a composite film-like material. The thickness of the base material 11 is not particularly limited, but is usually about 10 μm to 50 μm. Moreover, you may provide the peeling layer comprised by silicon resin, a fluororesin, etc. on the base material 11 by methods, such as a gravure printing method, die printing method, and reverse printing method, as needed.

  Note that a pressure-sensitive adhesive layer 12 made of an ultraviolet curable pressure-sensitive adhesive is provided on the substrate 11 so as to form a continuous picture pattern and / or characters and / or figures by printing. Even if the adhesive layer is continuous, it may be formed so as to form a pattern and / or characters and / or figures in a discontinuous manner. And it may be colorless and transparent or translucent, or may be colored. The thickness of the pressure sensitive adhesive layer 12 is about 5 to 40 μm, preferably 10 to 30 μm.

  When the thickness of the pressure-sensitive adhesive layer 12 is less than 5 μm, a pattern and / or characters and / or figures transferred onto a transfer surface such as a paper surface by the automatic winding type film transfer tool The pressure-sensitive adhesive layer 12 formed to take up has insufficient adhesive strength for attaching other articles. When the pressure-sensitive adhesive layer exceeds 40 μm, the tape is processed into a roll shape and stored for a long time. This causes the risk of blocking the back surface of the substrate 11. Further, if the thickness of the pressure-sensitive adhesive layer 12 is large, the size of the tape processed into a roll shape also increases, and the size of the coating film transfer tool having the feeding portion, the transfer portion, and the winding portion is large. It becomes so and handling property becomes worse.

  Further, the pressure-sensitive adhesive layer 12 made of an ultraviolet curable pressure-sensitive adhesive on the substrate 11 can clearly express a picture pattern and / or characters and / or figures such as fine characters, fine lines, and photographs, and the pressure-sensitive adhesive layer 12. It is preferable that printing is performed by a silk screen printing method in which there is little fluctuation of the thickness of the material and can be thickened. The UV curable pressure-sensitive adhesive does not increase in viscosity even when contacted with air during silk screen printing, and can be printed clearly on the screen plate without clogging. Note that the present invention is not limited to this as long as printing can be performed by a method such as gravure printing or coating with a coater so that the thickness of the pressure-sensitive adhesive layer 12 belongs to the optimum range on the substrate 11.

Co., Ltd., UV TAC (registered trademark), is colored on one side of a glassine paper that has been subjected to double-sided release processing, and pressure sensitive is made of an adhesive using the same. The adhesive layer 12 is printed by a silk screen printing method so as to mold a continuous picture pattern and / or characters and / or figures, irradiated with ultraviolet rays by a metal hydride lamp (180 mJ / cm ² ), and a picture having a thickness of 15 μm. A pressure-sensitive adhesive layer 12 having a pattern and / or characters and / or halftone dots and / or figures was obtained. Next, when this roll was slit into a width of 10 mm and mounted on an automatic take-up type film transfer tool equipped with a feeding part, a pressure transfer part and a take-up part, it was transferred to a transfer object, and it was straight and uniform. Thus, a pressure-sensitive adhesive layer on which a very clear picture pattern and / or characters and / or figures were formed was obtained. Next, when another article such as a paper surface was pressed against the surface of the transferred pressure-sensitive adhesive layer 12, it could be easily attached to the transfer target. Furthermore, when the adherend after sticking was peeled off from the transferee to which the adhesive layer was stuck, the adherend was destroyed.
