DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a printed matter for thermal transfer capable of clearly expressing the effect of embossing.

[0002]

2. Description of the Related Art As a conventionally known technique for producing a printed material for thermal transfer, a release agent layer is provided on one side of a base film, a pattern is printed, and a metal is vacuum-deposited on the entire printing side. A coating layer made of an alkali-resistant substance such as a medium is provided on a portion where the metal deposition layer is to be left (for example, a printed portion of a pattern), and then the metal deposition layer is washed with an alkali solution to remove other portions except for the coating layer. There is a method of removing the metal deposition layer of the portion.

[0003]

According to the conventional manufacturing method in which the metal deposition layer is left only in a necessary portion, the printed material for thermal transfer has a flat design and the like. However, there is a problem that the glossiness is poor and the luxuriousness is inferior even if the hologram is provided.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a method for producing a thermal transfer print which can clearly express the effect of embossing.

[0005]

In order to achieve the above object, a method for producing a thermal transfer print according to the present invention is characterized in that a release agent layer is provided on a base film and a design printing layer is provided on the release agent layer. Are sequentially provided, and a metal layer is vapor-deposited on the entire surface of the release agent layer including the design printing layer. After that, the metal deposition layer side other than the above-mentioned coating layer portion is removed by washing the metal deposition layer side with an alkaline solution, and then the above-mentioned coating layer side is micro-etched and then micro-etched The surface is coated with a transparent heat-sensitive adhesive.

[0006] In the printed matter for thermal transfer manufactured as described above, the fine dents formed by the micro-etching process are filled with a transparent adhesive, the processed surface becomes flat, and the portion where no metal vapor deposition layer is present becomes transparent. On the other hand, only the portion where the metal deposition layer remains can clearly express the emboss effect.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The manufacturing method of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 2, a release agent layer (usually transparent) 2 is provided on a base film (usually transparent) 1 and a design printing layer 3 is sequentially provided on the release agent layer 2. In 2, a metal such as aluminum is vacuum-deposited on the entire surface including the design printing layer 3, and a coating layer 5 made of an alkali-resistant substance such as medium is deposited on a portion of the metal deposition layer 4 where the metal deposition layer is desired to remain. Provide.

Thereafter, the metal deposition layer 4 is treated with an alkaline solution.
By washing the side, the metal deposition layer other than the portion of the coating layer 5 is removed, and then the coating layer 5 side is subjected to a micro-etching process (see FIG. 3) 6 and then to the first
As shown in the figure, the present invention is practiced by coating a transparent heat-sensitive adhesive (or pressure-sensitive adhesive) 7 for thermal transfer on the surface 6 of the micro-etching process. Note that 4a in the figure is a remaining metal deposition portion.

[0009] In the thermal transfer printed material manufactured as described above, the microetched portion of the transparent portion is filled with the adhesive 7 and the emboss disappears. For example, only the pattern by the metal vapor deposition layer is embossed on the transparent film. It is excellent in color and can further enhance the commercial value.

[0010] The film used in the production method,
Since the same materials as those of a general printed matter for thermal transfer can be used for the release agent, the printing ink, the alkali-resistant substance, the adhesive, and the like, detailed description thereof will be omitted.

[0011]

As described above, the present invention has the advantage that only a pattern having excellent glossiness can be displayed on the transfer object side.
It is possible to manufacture a thermal transfer printed material capable of expressing a clear embossing effect only on a partial metal deposition surface of a fantastic etching.
