Abstract

A decorative film includes a base film, a colored layer formed of UV curable ink, and an ink-absorbing layer. The ink-absorbing layer is formed between the base film and the colored layer, provided with voids therein, and contains filler made of photorefractive material.

First claim

What is claimed is:

1. A decorative film comprising:
a base film;
a colored layer which is a cured product of ultraviolet curable ink; and
an ink-absorbing layer formed between the base film and the colored layer, provided with voids therein, and containing filler made of photorefractive material,
wherein the filler reflects and scatters an ultraviolet radiation applied from above the colored layer, and
a part of the ink penetrates into the ink-absorbing layer and is cured in the ink-absorbing layer by the reflected and scattered ultraviolet radiation.

2. The decorative film according to claim 1 , further comprising:
a release layer formed between the base film and the ink-absorbing layer; and
a protective layer formed between the release layer and the ink-absorbing layer.

3. The decorative film according to claim 1 , wherein the part of the ink penetrates into the ink-absorbing layer in such a manner that each droplet of the ink has a shape tapering into the ink-absorbing layer from a surface of the ink-absorbing layer.

4. The decorative film according to claim 1 , wherein the ink-absorbing layer is partially exposed from the colored layer,
wherein the decorative film further comprises an adhesive layer coating both the colored layer and exposed portions of the ink-absorbing layer.

5. The decorative film according to claim 1 , wherein the filler contains photo-semiconductor material.

6. The decorative film according to claim 1 , wherein the filler contains conductive material.

7. The decorative film according to claim 1 , wherein the filler is composed of porous particles or contains voids.

8. A molded product comprising:
a body; and
a transfer portion formed on a surface of the body and including an ink-absorbing layer and a colored layer,
wherein the colored layer is a cured product of ultraviolet curable ink,
the ink-absorbing layer contains filler made of photorefractive material and is provided with voids therein,
the filler reflects and scatters an ultraviolet radiation applied from above the colored layer, and
a part of the ink penetrates into the ink-absorbing layer and is cured in the ink-absorbing layer by the reflected and scattered ultraviolet radiation.

9. The molded product according to claim 8 , wherein the part of the ink penetrates into the ink-absorbing layer in such a manner that each droplet of the ink has a shape tapering into the ink-absorbing layer from a surface of the ink-absorbing layer.

10. The molded product according to claim 8 , wherein the surface of the body is formed of a resin layer.

11. The molded product according to claim 8 , wherein the filler is composed of porous particles or contains voids.
