Reference numeral 10 indicates a heat-adhesive resin layer, and 11 indicates a cloth.

The transfer sheet 1 of the present invention has a structure in which a transfer pattern portion 3 having an island pattern formed by the half-cuts 4 is provided on a transfer sheet substrate 5 with an adhesive layer 6 interposed therebetween. There is.

As shown in FIG. 2, the laminated structure of the transfer sheet 1 includes a printing ink layer 7, a vapor deposition layer 8 and a polyethylene terephthalate layer 9 on a transfer substrate 2 composed of a transfer sheet substrate 5 and an adhesive layer 6. The transfer pattern portion 3 formed by the half-cut 4 has an island-like pattern, which is a laminate in which the heat-adhesive resin layer 10 is laminated and the pressure-sensitive adhesive layer 6 and the printing ink layer 7 are peelably laminated. It has been arranged.
As shown in FIG. 3A, the surface layer of the transfer handle portion 3 is formed by superposing the cloth 11 on the surface of the transfer handle portion 3 on which the transfer handle portion 3 is present, and thermocompressing it with a heating roll and a pressure roll. The heat-adhesive resin layer 10 melts and adheres to the cloth 11, the transfer pattern portion 3 is transferred to the cloth, and the adhesive layer 6 is laminated on the transfer sheet substrate 5 as shown in FIG. Transfer substrate 2 in the state
Is peeled off.

The outermost surface of the transfer pattern portion 3 transferred to the cloth 11 is the printing ink layer 7, and by the synergistic effect with the vapor deposition layer 8 on the lower surface of the printing ink layer 7, a glittery metallic sequin-like decoration is provided. The dough is finished. If the printing ink layer 7 is printed with a colorless and transparent ink, silver sequin-like decoration of aluminum vapor deposition can be performed, and if it is solid-printed with a transparent coloring ink, a metallic luster of any color tone can be obtained. For example, if you print it in transparent yellow, you can make a golden sequin-like decoration. When a transparent coloring ink is used, the design is arbitrary, but when an opaque ink is used, the metallic luster of the vapor deposition layer 8 printed by the opaque ink is destroyed, so printing with the opaque ink It is necessary to keep the handle in a small area. It is possible to diversify the design by solid-printing with a transparent coloring ink and then printing a pattern with another color ink.

As another structure of the transfer sheet 1, as shown in FIG. 4, a polyethylene terephthalate layer 9, a printing ink layer 7, and a vapor deposition layer 8 are formed on a transfer substrate 2 composed of a transfer sheet substrate 5 and an adhesive layer 6. And a heat-adhesive resin layer 10 are laminated, and the adhesive layer 6 and the polyethylene terephthalate layer 9 are peelably laminated, and the transfer pattern portion 3 formed by the half-cut 4 forms an island pattern. It can be arranged. When transferred with the transfer sheet having the above-mentioned structure, the surface of the transfer pattern portion 3 transferred to the cloth 11 is formed of the polyethylene terephthalate layer 9, so that a sequin-like cloth having excellent surface gloss and surface physical properties can be obtained. . The method of forming the printing ink layer 7 in the transfer pattern portion 3 is the same as the above case.

As the transfer sheet substrate 5 of the transfer sheet 1, a transparent and heat-resistant plastic film such as polyethylene terephthalate or biaxially oriented polypropylene is suitable. Although it is possible to use a two-layer structure in which a polyolefin resin such as polypropylene is extrusion laminated onto a paper such as kraft paper, the transfer sheet base material 5 is opaque when the kraft paper or the like is used. In this state, there is a drawback that the color tone or pattern of the transfer pattern portion 3 cannot be visually recognized from the outside. As the transfer sheet substrate 5, a polyethylene terephthalate film or a biaxially oriented polypropylene film having a thickness of 12 to 50 μm is suitable.

As the physical properties of the pressure-sensitive adhesive layer 6 provided on the transfer sheet substrate 5, those having low tackiness, excellent heat resistance and non-transferability are preferable. Examples of the resin that constitutes the pressure-sensitive adhesive layer 6 include rubber-based resins such as polyisoprene rubber, styrene-butadiene rubber, and butadiene-acrylonitrile rubber, acrylic ester-based resins, polyvinyl ether-based resins, chlorinated polyolefin-based resins, polyvinyl butyral-based resins, and the like. Can be used. If the coating thickness of the adhesive layer 6 is too thick, the fabric 12
3 to 10 μm is suitable because the transfer sheet substrate 5 adheres to the cloth 12 and becomes difficult to peel off when it is transferred to. In order to prevent the adhesive layer 6 from peeling off from the transfer sheet base material 5 and transferring to the cloth, by providing the adhesive layer 6 after performing an anchor coat on the transfer sheet base material 5,
The transfer of the pressure-sensitive adhesive layer 6 to the cloth at the time of transfer can be prevented. The pressure-sensitive adhesive layer 6 is applied to the transfer sheet substrate 5 by a gravure method or coating.

Acrylic resins, polyamide resins, polyester resins, Birni chloride resins, and urethane resins are suitable as the resin forming the printing ink layer 7.
It is used as a room temperature two-component curing type ink containing an isocyanate curing agent. The printing ink layer 7 is provided on the surface of the vapor deposition layer 8, and solid printing is performed on the entire surface by using a colored transparent ink in order to make the best use of the metallic luster of the vapor deposition layer 8, and a pattern of another color is provided on it as necessary. Is good. When the colored transparent ink is used, the pattern area is not limited, but when the opaque ink is used, it is necessary to print the vapor deposition layer 8 in a constant pattern in a narrow area that does not cover the entire surface.

In the case of the structure of the transfer sheet 1 shown in FIG. 2, a transparent resin layer may be provided on the ink surface as the printing ink layer 7, and in that case, the printing ink layer 7 is not transparent at the same time as printing. Print with colored ink. When the transfer sheet 1 is used to transfer onto the cloth 11, the transparent resin layer is a layer that forms the surface of the transfer pattern portion 3 and functions as a protective layer for the printing ink layer 7. Resins that can be used for the transparent resin layer include acrylic resins, vinyl chloride resins, polyester resins, urethane resins and the like. Further, the transparent resin layer provided on the surface of the printing ink layer 7 functions as a release layer for peeling the printing ink layer 7 from the surface of the adhesive layer 6 at the time of transfer. It is better to add agents.

The structure of the transfer sheet shown in FIG. 4 comprises a printing ink layer 7 on the surface of the polyethylene terephthalate layer 9 and a vapor deposition layer 8 on the surface of the printing ink layer 7, and is used as the printing ink layer 7. It is necessary to consider the vapor deposition suitability of the ink. By providing a primer for vapor deposition on the surface of the printing ink layer 7 and performing vapor deposition, the metallic gloss of the vapor deposition layer 8 becomes more excellent. When the heat-adhesive resin layer 10 is provided on the surface of the vapor-deposition layer 8, an anchor coat may be applied to the surface of the vapor-deposition layer 8. Further, if necessary, a release layer may be provided on the surface of the polyethylene terephthalate layer 9 opposite to the printing ink layer 7 to facilitate peeling from the pressure-sensitive adhesive layer 6.

Aluminum vapor deposition is suitable as the vapor deposition layer 8, and the thickness of the vapor deposition layer is arbitrary, but vapor deposition having a general thickness of 30 to 60 millimicrons is suitable. As the polyethylene terephthalate layer 9, a biaxially stretched polyethylene terephthalate film having a thickness of 12 to 50 μm is preferable, and an aluminum vapor-deposited biaxially stretched polyethylene terephthalate film can also be used.

As the heat-adhesive resin layer 10, cloth such as cloth is used.
Suitable for 11 is a heat-adhesive resin with a relatively low melting point, which has excellent adhesiveness, such as acrylic ester resin, polyvinyl ether resin, polyvinyl acetate resin, ethylene-vinyl acetate copolymer resin, vinyl chloride- Vinyl acetate copolymer resin, polyamide resin, polyester resin, polyvinyl butyral resin, etc. can be used. Thermal adhesive resin layer 10
Thickness is in the range of 3-30 microns, 5-1
5 micron is suitable. When the heat-adhesive resin layer 10 is used by being laminated on the polyethylene terephthalate layer 9 as in the transfer sheet 1 shown in FIG. 2, the heat-adhesive resin composed of the modified polyester resin is formed into a biaxially stretched polyethylene terephthalate film. It is convenient to use a laminated two layer polyethylene terephthalate film.
If the surface of the heat-adhesive resin layer 10 is tacky, a release film made of biaxially oriented polypropylene film or the like may be laminated and used.

The heat-adhesive resin layer 10 may be provided on the polyethylene terephthalate layer 9 before printing the printing ink layer 7. On the other hand, an adhesive layer 6 is provided on the transfer sheet substrate 5 by gravure printing or coating. Then, the pressure-sensitive adhesive layer 6 surface of the transfer sheet substrate 5 and the printing ink layer 7 surface of the polyethylene terephthalate 9 are overlapped and pressed to be bonded. A pattern-shaped half-cut 4 reaching the transfer sheet base material 5 from the surface of the heat-adhesive resin layer 10 of the above-mentioned laminated body is applied, and only the transfer pattern portion 3 formed by the half-cut 4 is left, and the other portions are adhesive layer. The transfer sheet 1 is completed by peeling and removing between 6 and the printing ink layer 7.
