Abstract

PURPOSE:To obtain the titled transfer material easily and inexpensively, by a method wherein a hardenable resin layer is provided on a base sheet provided with a releasable layer, and after incompletely hardening the resin layer, an organic solvent is brought into contact with the resin layer to generate cracks in the resin layer, then the resin layer is completely hardened, and thereafter a transfer layer is provided. CONSTITUTION:The releasable layer 2 consisting of an acrylic resin or the like is provided on the base sheet 1 consisting of a polyethylene terephthalate film or the like, the hardenable resin layer 3 consisting of melamine, acryl or the like is provided thereon, and thereafter the resin layer 3 is incompletely hardened by heating or other means. Then, an organic solvent such as a ketone, an ester or a hydrocarbon is brought into the surface of the resin layer 3 to generate cracks 4 in the surface, and the resin layer 3 is completely hardened by a treatment such as heating. Thereafter, the transfer layer 5 having an adhesive layer 6 or the like at the outermost surface and comprising, as required, a vapor-deposited metallic layer 7 and/or a colored layer 8 consisting of a dye or a pigment is provided by printing, coating or other means. EFFECT:A crack pattern of a desired roughness can be easily obtained.

Description

[Detailed description of the invention] It is about law.

The transfer material is provided on the base sheet and rotated one by one.-14. By applying means such as pressing and heating the layer onto the printing surface, it is possible to enhance the decorative effect of the transferred object and express letters and patterns on the surface. It is used for this purpose. Due to the above reasons, a crack has appeared in recent years.Transfer 4:
4 has been created (see Japanese Patent Publication No. 55-7836). However, in this invention, if you press the % type, If. Since the IY method relied on the note method of forming irregularities on the surface of the base sheet, it had the following drawbacks. Therefore, it is very difficult to express encounters by pressing with one type, so it is expensive to create stffl types, and the crack pattern is not planned. become something.

In addition, when using a rubbing operation, it is time-consuming because four times the operation is required, and it is difficult to obtain a crack pattern with the desired roughness.

The present inventors attempted to improve the above-mentioned drawbacks, and as a result of various research and considerations, they were able to complete the present invention. That is, in this method, a release layer 2 is provided on a base sheet 1, and a curable resin layer 8 is provided on the base sheet 1, and then the curable resin layer 8 is semi-cured by a treatment such as heating. The curable resin layer 3 is characterized in that after the surface of the curable resin layer 3 is brought into contact with an organic solvent to cause cracks 4, the curable resin layer 3 is completely cured by treatment such as heating, and then the transfer layer 5 is provided. This is a method of installing rolling materials that creates a crack pattern.

In the following, the present invention will be explained in more detail. first,
Using the material used for normal transfer materials, make one basic sheet) 1
On the top (a release layer 2 is provided. The base sheet 1 is a polyethylene terephthalate film 2 blue, and the release layer M2 is 174
Resins that can be used include acrylic resins, polyolefin resins, cyclized vinyl, vinyl acetate, and the like.

4. Apply a curable resin layer 3 to the upper part of the layer 2 partially or completely using a curable resin by printing, coating, etc. using a trowel (
, 41 fig. 11@). Here, the curable resin is /III
Heat, ultraviolet irradiation, and irradiation with heat, UV irradiation, etc. 1. The resin, which hardens by applying a tar ring such as X-ray irradiation, is evaporated. For example, thermosetting resins such as melamine and acrylic and ultraviolet curable resins such as urethane acrylate and polyester flare acrylate are used.゛The formed curable resin layer 3 is subjected to an appropriate treatment capable of curing the curable resin used.

The curable resin layer 3 is brought into a semi-cured state. The semi-cured state is a state beyond completely cured, and the heating temperature, irradiation intensity, and processing time must be adjusted.
The curable resin layer 3 achieves the desired 11-
After bringing it to a semi-hardened state, apply Ketones, esthetics, ashing water, etc. (Kundenso 41) using methods such as dipping, printing, Megsaw method, etc. .In this 1st process, a crack pattern is formed on the IIψ conversion layer 1c, A layer 3!& surface (see Section 2, Section 1).The cause of this crack 4 is not clear, but ρ-p improved hardenability (
(to) When the relatively less hardened parts of the fat are dissolved and removed by contact with the organic solvent, at the same time, the more hardened parts are condensed due to the coagulating force inside the resin.
It is presumed that they are formed through mutual interaction. A crack pattern with different roughness is created depending on the degree of hardening of the semi-hardened state and the solvent treatment conditions.

Next - The curable resin layer is completely cured by the above-mentioned treatment such as /11P. Thereafter, a transfer layer is printed and placed on it using a trowel. Transfer N115 means a layer 7 consisting of an adhesive layer 6 or a colored layer having adhesive properties on the outermost surface, and if necessary, one core consisting of a gold II adhesive layer 7, dye, or pigment. It includes a colored layer 8 (see FIG. 3).

When it is desired to partially form a nail cleft pattern, a resist layer 9 can be formed on the necessary portions of the resin layer 3 before contacting with an organic solvent. letter,
Pictures, etc. can be formed into patterns (see Fig. 4). The resist layer 9 may be formed of any material as long as it is sparingly soluble or insoluble in organic solvents; for example, it can be formed using a water-soluble resin such as polyvinyl alcohol. The resist layer 9 is formed after being brought into contact with an organic solvent.

It is removed by a method such as cleaning, and then a reverse q layer 5 is provided (@Φ
(see figure).

Since the present invention is a #-adjustment method for transfer materials as described above, it is possible to easily create many types of R4 and tear patterns, and designs that are not planned can be borrowed. Father, the process is also easy k, su, (#1
By appropriately selecting the fat and processing conditions, it is easy to obtain a crack birch hammer with the desired thickness. 4 cracks in the shape of a partially bent square pattern can also be constructed as a surface funeral. ,,Therefore, the transfer material thus obtained can be used as a material by using various base materials as shown in Table 1.
The three-dimensional shape of m can be used to create a decorative effect such as a platform.
So υ) Wide 111 use is expected.

Hereinafter, 210 embodiments of the present invention will be described. All parts represent parts by weight.

<Example>> Methyl methacrylic acid 1 fat was applied as a peeling layer to a polyester film (25 μm thick), and on top of that, Medicum, whose main component was melamine, to which 0.5 part of an organic acid hardening accelerator was added. After coating the entire surface.

Heat dry at 150°C for 15 seconds.

Next) apply this methyl ethyl ketone to this surface to generate cracks, and heat dry it again using a trowel at 10°C for 20 seconds.

Further, aluminum was vapor-deposited using a conventional method and an adhesive was coated to obtain a transfer layer having a metallic crack pattern on the entire surface.

<Example 2> IJI delamination was provided on a polyester film using a chlorinated olefin resin, and on top of that, a pattern was provided using 30 parts of a butylated melamine resin (140C).
Heat treatment was performed for 20 seconds. Thereafter, ethyl acetate was gravure coated to generate cracks in all four parts. Then 1 again
5 oj] for 30 seconds. Thereafter, a methyl methacrylate resin was applied over the entire surface to obtain a transfer material having a blue pattern with cracks.
