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 producing a decorative material in which the front side of the pattern appears to have 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 or an interior lighting fixture, or a daily-use miscellaneous goods, and can be applied to a wide range of applications in the future.

The method for producing the ink is, for example, an ink having a resin having a low adhesive strength to the substrate or a relatively brittle dry coating having a low resin component on a transparent or semitransparent plastic substrate. According to the above, a linear negative or positive uncoated net-like fine pattern layer, an ink layer having an adhesive force to the substrate and having a considerable adhesive force to the fine pattern layer, and an ink layer On the other hand, a white to light-colored ink layer having adhesiveness and an ink layer are provided by screen or gravure or offset printing of a design pattern, etc.,
There is a method of obtaining by peeling the resin (or ink having a dry film) from the substrate by a chemical or mechanical treatment.

When a transfer sheet is used to transfer a pattern to a transparent or translucent transfer target to produce a pattern, the base film of the transfer sheet is used as a pattern, and a portion not requiring transfer is peeled off in a film form. As a layer, it is appropriately printed in the fine pattern, and a pattern or a solid pattern is overlaid and printed on the layer, and finally, the excess pattern portion is removed from the film-like release layer, or the registration is made on the fine pattern. While there is a method of printing the pattern in layers. Furthermore, a method of transferring with a transfer roll having a fine pattern of unevenness using a transfer sheet on which a pattern or a solid pattern having an appropriate hiding property is transferred, or the transparent or semitransparent base film of the transfer sheet is used. The part that is not needed as a pattern when transferred to the plastic substrate is printed in advance with water-soluble ink, the pattern or solid pattern is printed over it, and finally the unnecessary part is removed by a washing process. There have been carried out methods such as a method of printing a picture pattern or a solid pattern, providing an adhesive layer on the entire surface, and then concealing an unnecessary portion with a reaction curable ink so that the unnecessary portion is not transferred.

[0005]

However, the above-mentioned conventional methods have a problem that high printing accuracy is required and workability is poor.

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 which is inexpensive, has good workability and good design. ..

[0007]

In order to achieve the above object, the present invention provides a base 1 with an ultraviolet curable ink layer 2 having no adhesiveness to the base 1 in a mesh shape, a dot shape, The first pattern layer 3, the solid hiding layer 4, the second pattern layer 5, or the second pattern layer 5, which has a desired fine pattern such as a stripe pattern and has adhesiveness to the base 1, are provided in this order on the ultraviolet curable ink layer 2. The transparent or semitransparent transfer target 8 is superposed on the transparent adhesive layer 6 of the transfer foil 7 formed by stacking any one of the layers and stacking the transparent adhesive layer 6 on the stack, and the transfer is performed. The foil 7 and the transferred material 8 are hot-pressed, and after the hot-pressing, the transfer foil 7 is peeled off from the transferred material 8 and the ultraviolet-curable ink layer 2 of the transfer foil 7 is transferred to the ultraviolet-curable ink. A layered product having a desired fine pattern on the ink layer 2 is peeled and transferred to the transfer target 8 side. A method for producing a decorative material having see-through property, which comprises causing.

[0008]

In the present invention, the transfer foil is provided on the upper surface of the base,
An ultraviolet curable ink layer that does not have adhesiveness to this base is provided in a desired fine pattern such as a mesh pattern, a dot pattern, and a stripe pattern, and a first pattern layer, a solid masking layer, and a second pattern layer are laminated on the upper surface thereof. Or any one of these layers is laminated, and a transparent adhesive layer is further laminated on the upper surface thereof. Then, an object to be transferred is superposed on the transparent resin layer side of the transfer foil and hot pressed. At this time, the adhesive force A between the base and the laminate via the ultraviolet curable ink layer on the transfer foil side is equal to that between the transfer body and the laminate via the transparent adhesive layer on the transfer body side. It is smaller than the adhesive force B. Further, the adhesive force B between the transferred body and the laminated body via the transparent adhesive layer is smaller than the adhesive force C between the base and the laminated body on the transfer foil side (that is, A
<B <C. ). Therefore, in the superposed state, the transferred body has a laminated body part supported (adhered) in a desired fine pattern by the transparent adhesive layer, while the base side has the laminated body and the base. A state in which the laminated portion supported by the negative pattern is held by adhesion is obtained.

After that, by peeling off the transfer foil (base), the laminated body portion having a desired fine pattern on the UV-curable ink layer is peeled off from the UV-curable ink layer and supported on the base. The laminated body portion of the negative pattern thus formed is removed from the transferred body side, and the laminated body is left on the transferred body in a desired fine pattern.

FIG. 5 shows a state in which the transfer foil 7 is used to transfer the transferred material to the transfer object 8. The transparent adhesive layer 6 of the transfer foil 7 is shown in FIG.
And the transfer foil 7 are overlapped with each other so as to face the transfer target body 8 and subjected to hot-pressing, after which the transfer foil 7 is peeled off. In a state where they are overlapped and subjected to a hot press, adhesion between the base 1 and the laminate (the first pattern layer 3 and the solid hiding layer 4) via the ultraviolet curable ink layer 2 on the transfer foil 7 side. The force is smaller than the adhesive force between the transferred body 8 and the laminated body via the transparent adhesive layer 6 on the transferred body 8 side. The adhesive force between the transferred body 8 and the laminate via the transparent adhesive layer 6 is smaller than the adhesive force between the base 1 and the laminate on the transfer foil 7 side.
Therefore, the transferred body 8 is in a state of holding a laminated body portion supported (adhered) in a desired fine pattern by the transparent adhesive layer 6, while the base 1 side adheres the laminated body and the base 1 together. Thus, the laminated portion supported by the negative pattern is held.

After that, the transfer foil (base 1) 7 is peeled off, so that the laminate portion having the desired fine pattern on the ultraviolet curable ink layer 2 is peeled off from the ultraviolet curable ink layer 2. Further, the laminated body portion of the negative pattern supported by the base 1 is removed from the transferred body 8 side, and the laminated body remains on the transferred body 8 in a desired fine pattern, thus providing a transparency with the desired fine pattern. A decorative material having is obtained.
