Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a transfer sheet having a partially deposited layer having a pattern partially having metallic luster.

(Conventional technology) As a transfer sheet with a conventional partially deposited layer.

A release agent layer and a pattern layer are formed on the film base material.

A water-soluble removal layer is formed on the parts of the pattern layer that do not require metallic luster, a metal film is deposited on the entire surface, and the removal layer is removed from the metal film by washing with water. After removing only the corresponding portions together with the removal layer, the entire surface Kg
Those obtained by forming a thermal adhesive layer, or those obtained by forming a release agent layer on a film base material, forming a metal film on the entire surface by vapor deposition on the release agent layer, and forming a metal film on the entire surface of the release agent layer. The pattern is partially printed with chemical-resistant paint, the metal film is partially removed by acid or alkali cleaning, and then a heat-sensitive adhesive layer is formed on the entire surface or partially. Are known.

(Problems to be Solved by the Invention) In the former method, each step of immersion in water, brushing and drying during washing requires a long time, and since the removal layer is a water-based ink, printing suitability is poor. Precise printing cannot be done with high productivity, and even more.

There is a drawback that the edges (contours) of the partially vapor-deposited metal film layer formed by dissolving and removing the removal layer do not appear sharp, and in the latter method, there are problems in the treatment of waste liquid of acid and alkali cleaning chemicals. In addition, in the case of back-printing, it is necessary to print by aligning the pattern layer on top of the vapor-deposited metal film layer and the vapor-deposited protective layer below, making it impossible to obtain high-precision products in the form of long rolls. It had the disadvantage of being.

The present invention has been made in view of the above points, and an object of the present invention is to provide a transfer sheet having a partially vapor-deposited layer that has a clear and sharp vapor-deposited metal pattern and is easy to manufacture.

(Means for Solving the Problems) The transfer sheet of the present invention includes a film base material and a release agent layer formed entirely on the film base material.

A pattern layer printed on the release agent layer, and a metal film layer formed on the portion of the pattern layer that requires metallic luster;
It is formed by sequentially laminating an adhesive layer formed entirely on the metal film layer. The metal film layer is formed by forming a removal layer that is soluble in an organic solvent that does not dissolve the peeling layer and the pattern layer on a portion of the pattern layer that does not require metallic luster, and covering the entire surface of the removal layer with metal. A film formed by vapor deposition, removing the removal layer by dissolving it with an organic solvent that does not dissolve the release layer and the pattern layer, and removing the metal film formed on the removal layer together with the removal layer. It is.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

The blind is the film base material that is the base material of the transfer sheet. As the film base material 1, a transparent or translucent film made of polyester, nylon, polypropylene, celonone, etc. can be used.

These films can also be used alone.

It can also be used in complexes. The thickness of the film used as the film base material 1 is preferably about 6 to 100 microns.

A release agent layer 2 is formed entirely on the film base material 1 . Since the release agent layer 2 is provided to separate the film base material 1 from the transfer layer after transfer, it is formed using a release agent that has a small adhesive force with the film base material 1. however,
The adhesive force of the release agent layer 2 to the film base material must not be too small.

It must be able to maintain the required adhesion before transfer. This release agent is acrylic-based.

Transparent ink using a rubber-based or vinyl-based synthetic resin as a vehicle, or colored ink colored by adding pigments, dyes, etc., can be used. The release agent layer 2 is formed by applying a release agent to a thickness of about 1 to 10 μm on the film base material 1 and drying it. The release agent is applied by gravure coating, roll coating, air coating, kiss coating, spray coating, solid coating using silk screen, 70-coating, or the like.

A pattern layer 3 is printed on the release agent layer 2. As the ink for the pattern layer 3, an ink obtained by kneading a vehicle with a pigment or dye colorant, a plasticizer, a stabilizer, other additives, a solvent, or a diluent can be used. As this vehicle.

For example, homopolymers of acrylic acid monomers or methacrylic acid monomers such as polymethyl methacrylate, polyethyl methacrylate, polyethyl acrylate, and polybutyl acrylate, or comonomers of these acrylic acid monomers and methacrylic acid monomers. Alcohol-insoluble resins such as copolymer resins, polystyrene, poly-α-methylstyrene, styrene-based resins and styrene-based copolymer resins, cellulose acetate, vinyl chloride, polyester resins, etc. are preferred, and one type from these Alternatively, two or more types can be selected and used. Picture layer 3 is.

Printing is performed by a known printing method such as a gravure printing method, an offset gravure printing method, a silk screen printing method, an offset printing method, an electrostatic printing method, or a jet printing method.

As shown in FIG. 1, a metal film layer 4 is formed by vapor deposition on the portions of the pattern layer 3 that require metallic luster. The metal film layer 4 is formed as follows. That is, the removal layer 5 is printed and formed on a portion of the pattern layer 3 that does not require metallic luster.

The ink for the removal layer 5 includes a vehicle, a colorant, a plasticizer, and other additives.

A material obtained by kneading a solvent or the like can be used.

As the vehicle, a resin that can be dissolved in an organic solvent that does not dissolve the release layer and the pattern layer is used, and preferably alcohol-soluble resins such as polyamide resin, maleic acid resin, ester gum, shellac, ethyl cellulose, and polyvinyl acetate are used. These can be used alone or in combination of two or more. The removal layer 5 is printed by a known printing method such as a gravure printing method, an offset gravure printing method, a silk screen printing method, an offset printing method, an electrostatic printing method, or a jet printing method. Next, the pattern layer 3 and the removal layer 5
A metal film is deposited on the entire surface. This metal film is formed by vacuum-depositing metal such as aluminum, tin, silver, copper, etc. to a thickness of about 400 to 600 Å.

Next, the metal film surface is cleaned with an organic solvent that does not dissolve the release layer and pattern layer but dissolves the removal layer.

As the organic solvent, when the removal layer is formed of an alcohol-soluble resin, a single or mixed solvent such as ethyl alcohol or ethyl alcohol is used in addition to Ingropil alcohol. The solvent penetrates this metal film and dissolves the removal layer 5, and the metal film at the tip corresponding to the removal layer 5 is removed as the removal layer 5 is dissolved, and as shown in FIG. The metal film layer 4 remains only in areas of the layer 3 that require metallic luster.

As shown in FIG. 3, an adhesive layer is formed on the metal film layer 4 for bonding it to the transfer target 7. The adhesive layer 6 is formed by applying an adhesive after the solvent has dried. This adhesive is a heat-sensitive adhesive that has sufficient adhesive strength to the metal film layer.

Furthermore, this adhesive may be acrylic,
Transparent ink using a transparent resin vehicle such as polyvinyl acetate, rubber, or olefin, or colored ink colored by adding pigments, dyes, etc., is selected and used. This adhesive is applied by gravure coating or roll coating, similar to the release agent application.

Air 1-47:'-), kiss coat, spray coat, solid coat by silk screen, 70-coat, etc. are used.

When actually using the transfer sheet obtained as described above, as shown in FIG.
The film base material 1 is then peeled off immediately after heat and pressure bonding is performed. The film base material 1 is peeled off from the release agent layer 2, and the printed pattern is transferred to the transfer target 7.

Next, the present invention will be explained in more detail by giving specific examples.

Example 1 A polyester film (thickness 25 μm) was used as a film base material, and an acrylic resin-based transparent ink was gravure printed on the entire surface in a continuous roll to form a release agent layer, and a pattern layer was formed using an acrylic resin-based ink. .

Subsequently, a removal layer was formed by gravure printing on areas where metallic luster was not required using the following ink.

Alcohol-soluble maleic acid resin 8, weight part layer color pigment 51
Denatured alcohol/isopropyl alcohol (1/'1)
87 N After forming an aluminum vapor deposition film layer with a thickness of about 50 OA by vapor-depositing aluminum over the entire surface of the printed surface, it was washed with isopropyl alcohol.

The removal layer was dissolved, and the aluminum vapor deposited film layer on the removal layer was removed together with the removal layer. After drying, a transparent acrylic resin adhesive was applied to the entire surface to obtain the intended transfer sheet. On this transfer sheet, a partially vapor deposited layer with a sharp outline and a clear pattern was formed in a desired continuous pattern.

(Effects of the Invention) In the present invention, the metal film layer partially provided in the areas that require metallic luster can be dissolved in a predetermined solvent that does not dissolve the peeling layer and the pattern layer in the areas of the pattern layer that do not require metallic luster. A removal layer is formed, gold JIIM is deposited on the entire surface of the removal layer, and the removal layer is dissolved and removed with a predetermined solvent to remove the metal film layer formed on the removal layer together with the removal layer. Since it is formed by removing the metal film, the partial removal of the metal film is carried out reliably and uniformly in any part, and as a result, the pattern of the vapor-deposited metal is formed sharply with fine IIt, which is different from the conventional pattern of the vapor-deposited metal. Also has the effect of eliminating blurred images. The removal layer.

By using an oil-based ink that is soluble in an insoluble organic solvent for the release layer and the pattern layer, printing properties are excellent when forming the removal layer, and the work can be performed efficiently.

In addition, since an organic solvent is used to dissolve and remove the removal layer, the solvent can be easily dried and the workability can be improved. Furthermore, it has the advantage that printing can be performed regardless of front or back printing, similar to the conventional method using water-based ink.
