Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a special decorative material,
Specifically, the pattern transferred to the transparent base material or sheet is the same as or different from the one viewed from the base material or sheet side, and the one viewed from the transfer side. You can observe only the picture on the front side without interference.
Further, the present invention relates to a method for manufacturing a decorative material, characterized in that the picture on the front side looks as if it disappeared due to the presence or absence of a light source from the back side or the strength of the light source.

[0002]

2. Description of the Related Art A decorative material which has a different pattern on the front and back sides with a transparent or semi-transparent base material or sheet as a boundary and looks like the pattern on the front side disappears when there is light from the back side has been conventionally used. However, from the viewpoint of its design, it is used as a decorative material such as a glass window and an indoor certification device, and a daily-use miscellaneous goods, and can be applied to a wide range of applications in the future.

However, as the manufacturing method thereof, the following conventional techniques are known.

A transparent or semi-transparent plastic base material, on which a resin having a low adhesive strength to the base material is applied, such as a linear negative or a positive plain network fine pattern layer,
A layer having an adhesive force to the base material and a little adhesive force to the fine pattern layer, a white to light color ink layer having an adhesive force to the ink layer, and a design pattern, etc. Is provided by screen or gravure or offset printing to provide an ink layer, and the resin is peeled off from the substrate by a chemical or mechanical treatment.

When a pattern is transferred onto a transparent or semitransparent substrate to be transferred using a transfer sheet, the base film of the transfer sheet is appropriately designed as a pattern, and a portion not requiring transfer is appropriately used as a film-like release layer. A method of printing in the fine pattern, printing a pattern or a solid pattern on top of it, and finally removing the excess film.

A method in which a pattern is laminated and printed while registering fine patterns.

A method in which a transfer sheet on which a pattern or a solid pattern is printed while appropriately concealing property is used, and transfer is performed by the transfer roll having the fine pattern of irregularities.

On the base film of the transfer sheet, a portion which is not required as a pattern when transferred to the transparent or translucent plastic substrate is printed with a water-soluble ink, and a pattern or a solid pattern is overlaid and printed. Finally, the unnecessary part is removed by a washing process.

After printing a picture pattern or a solid pattern and providing an adhesive layer on the entire surface, an unnecessary portion is covered with a reaction curable ink, and an unnecessary portion is not transferred.

[0010]

However, a method of preliminarily providing a fine pattern layer of a resin having a low adhesive force on a substrate, an adhesive layer, a pattern, etc., and peeling the resin from the substrate by a chemical or mechanical treatment. Then, in addition to poor workability, there is a defect that the pattern is missing and the stability is poor.

A method of printing a fine portion not requiring transfer on a base film, printing a pattern or a solid pattern on the base film, and finally removing the excess film has poor workability and causes a defective rate. It was getting higher.

In the method of laminating and printing a pattern while registering it in a fine pattern, it is difficult to prevent the pattern from sticking out because a high level of precision is required for the alignment accuracy of each layer.

The method of transferring with a transfer roll having a fine pattern of unevenness using a transfer sheet has the drawbacks that the transfer roll cost is expensive and the pattern reproducibility is low.

In the method of printing the unnecessary portion on the base film of the transfer sheet with a water-soluble ink, printing a pattern or a solid pattern on top of it, and finally removing the unnecessary portion with water. There were many defects left behind, and there was the drawback that the edge linearity was poor.

In a method in which a pattern or a solid pattern is printed and an adhesive layer is provided on the entire surface, then unnecessary portions are covered with a reaction curable ink, and unnecessary portions are not transferred, with a reaction curable ink. Workability at the time of the process of doing becomes a problem. Also, since it is a wet process, workability is poor.

[0016]

However, these methods are required to have a high printing accuracy, have poor workability, and have a high defect rate, so that other methods have been desired.

The present invention is intended to solve the above-mentioned drawbacks of the prior art, and an object thereof is to provide a decorative material having good workability and good design.

[0018]

In a method for producing a decorative material having a see-through property, a desired fine negative pattern such as a mesh, a dot or a stripe is previously formed on a transparent or semi-transparent transfer substrate with a water-soluble ink. Is prepared in advance, and a transparent release varnish layer is formed on the entire surface of the transfer foil, a concealing pattern layer in which a pattern layer is laminated above or below the solid concealing layer, or both, and an adhesive layer are sequentially laminated. Is superposed on a transparent or semitransparent transfer base material and pressed to transfer the entire surface, and then the transparent or semitransparent transfer base material is washed with water to produce a decorative material having transparency.

A transparent peeling varnish layer is formed on the entire surface of the base film of the transfer foil, and a masking pattern layer and an adhesive layer are formed by laminating a pattern layer on the peeling varnish layer in this order, either above or below the solid masking layer. Transfer foil on which a desired fine negative pattern such as a mesh, dot, stripe, etc. is made with water-soluble ink is laminated on a transparent or semi-transparent substrate and pressed to transfer the entire surface. Then, a transparent or semi-transparent transfer substrate is washed with water thereafter to produce a transparent decorative material.

[0020]

When the method for producing a transparent decorative material according to claim 1 is employed, a transparent or semitransparent transfer base material is preliminarily coated with a water-soluble ink in a desired fine negative pattern such as a mesh, a dot or a stripe. Make a pattern.

On the other hand, on the base film of the transfer foil, a transfer foil is formed by sequentially laminating a transparent release varnish layer on the entire surface, a concealment pattern layer having a pattern layer laminated on either or both sides of a solid concealment layer, and an adhesive layer. , The transparent or translucent substrate to be transferred is overlaid and pressed to transfer the entire surface.

At this stage, the transfer foil still remains on the entire surface of the transfer target substrate.

Next, when the transparent or semitransparent transfer base material on which the transfer foil is still left on the entire surface is washed with water, the water-soluble ink provided in advance works to remove the pattern layer and the like on the base material. The transfer foil is removed together, and a desired net-like, dot-like, or stripe-like pattern is partially formed on the transferred substrate.

When the method for producing a transparent decorative material according to claim 2 is adopted, a transparent peeling varnish layer is formed on the entire surface of the base film of the transfer foil, and on the peeling varnish layer, the transparent covering varnish layer is formed on and under the solid hiding layer. A transfer foil, in which a concealed pattern layer in which a pattern layer is laminated on one or both of them or an adhesive layer, is laminated in order and a desired fine negative pattern such as a mesh, a dot, or a stripe is formed with a water-soluble ink is water-soluble. The ink is placed on a transparent or semi-transparent base material to be transferred, and the whole surface is transferred by pressing.

What is made by the above method is claim 1.
Similarly, the transfer foil still remains on the entire surface of the transfer target substrate.

Next, when the transparent or translucent substrate to be transferred, on which the transfer foil is still remaining, is washed with water, the water-soluble ink provided in advance causes the portion of the pattern layer or the like on the substrate to be washed. The transfer foil is removed together, and a desired net-like, dot-like, or stripe-like pattern is partially formed on the transferred substrate.

EXAMPLES The present invention will be described in more detail below with reference to examples.

FIG. 1 shows an embodiment of the transfer foil of the present invention, which is adhered to a base film 1 such as a polyester film, a polypropylene film, a polyethylene film, a polyphenylene sulfide film, or a nylon film in some cases. A transparent release varnish layer 2 is provided on the entire surface of the base film 1 with a binder having a low property, for example, an acrylic resin ink.

On the release varnish layer 2, for example, the first pattern layer 3,
A hidden pattern layer composed of a solid hidden layer 4 and a second pattern layer 5 is sequentially provided. The first pattern layer 3, the solid hiding layer 4, and the second pattern layer 5 are usually used for transfer and have good hiding properties, such as acrylic, chlorinated rubber, vinyl chloride, vinyl acetate, chlorinated. Any of vinyl-vinyl acetate copolymer type, urethane type, polyester type and the like can be used. However, one of the first pattern layer 3 and the second pattern layer 5 is not always necessary.

The first pattern layer 5 is provided on the entire surface or a part of the release varnish layer 2 by a method such as gravure printing, offset printing, screen printing, electrostatic printing, ink jet, etc., if necessary. Letters, pictures, etc. are completely arbitrary.

The second pattern layer 5 is provided on the whole or a part of the solid hiding layer 4 by a method such as gravure printing, offset printing, screen printing, electrostatic printing, ink jet, etc., and has a design. Letters, pictures, etc. are completely arbitrary.

If the second pattern layer 5 is present, the whole surface transparent adhesive layer 6 is provided on the second pattern layer 5, and on the solid hiding layer 4 if it is not present.
The transparent adhesive layer 6 is generally made of acrylic resin, urethane resin, vinyl chloride vinyl acetate, polyester resin, ethylene vinyl acetate resin, chlorinated polypropylene resin, etc., although it depends on the substrate to be transferred.

The transfer foil 7 can be obtained by the above steps.

FIG. 2 shows an example of the transferred substrate 9 of the present invention. The transparent or translucent transferred substrate used here is polystyrene, AS, polyvinyl chloride, acrylic,
Polyethylene, polyethylene terephthalate, polypropylene, polycarbonate, polyacrylonitrile, glass, etc. can be used.

A desired fine negative pattern 10 having a mesh shape, a dot shape, a stripe shape or the like is formed on a transparent or semitransparent transfer substrate 9 with a water-soluble ink such as polyvinyl alcohol to obtain a transfer substrate 7. There is also a method.

Although the desired fine negative pattern 10 is applied to the transparent or semi-transparent substrate 9 to be transferred this time, the desired fine negative pattern 10 may be obtained on the transfer foil 7.

FIG. 3 is a cross-sectional view after the transfer foil 7 of the present invention is superposed on the transferred base material 9 and the entire surface is transferred by a press to form the base material 9. In this case, a simple press may be used, but a hot press is more efficient.

FIG. 4 is a sectional view when the base film 1 is removed thereafter. In general, the base film 1 has no brittleness and therefore needs to be removed before washing with water. It is more efficient to peel it off as part of the hot pressing in the previous step.

FIG. 5 is a view in which the base material 8 was washed with water after that, and the desired fine negative pattern 10 was formed on the transparent or translucent base material 9 to be transferred.

The pattern transferred to the transparent base material or sheet in this manner is the same as or different from the one viewed from the base material or sheet side and the one viewed from the transfer side.
Only the design on the front side can be observed without being interfered by the designs on the opposite sides, and further, the decorative material that appears as if the design on the front side disappeared due to the presence or absence of the light source from the back side or the strength of the light source was obtained.
