Abstract

In a decorative material, a matting agent is added to, of a first gloss-adjusting layer and a second gloss-adjusting layer, one with lower gloss, where the matting agent has a particle diameter of less than 1.0 times the thickness of the gloss-adjusting layer with lower gloss. The matting agent can be thereby exposed to the surface while floating in the gloss-adjusting layer. Accordingly, a sufficient matting effect can be obtained in front observation, and unevenness imparted to the surface can be reduced; thus, the effect of scattering obliquely entering light is weakened, and the matting effect can be reduced when observed obliquely. Therefore, a picture pattern expressed by the difference in gloss, i.e., a design, can be made invisible when observed obliquely.

First claim

What is claimed is:

1. A decorative material comprising:
a first gloss-adjusting layer provided on a substrate, and
a second gloss-adjusting layer partially provided on the first gloss-adjusting layer,
and having gloss that is different from that of the first gloss-adjusting layer;
with a matting agent added to, of the first gloss-adjusting layer and the second gloss-adjusting layer, the one with lower gloss, where the matting agent has a particle diameter of less than 1.0 times a thickness of the gloss-adjusting layer with lower gloss, wherein the gloss-adjusting layer, to which the matting agent is added, consists of a lower layer positioned on the substrate side and a upper layer positioned on a side opposite to the substrate side, a thickness of the upper layer is the same as a thickness of the lower layer, each of the upper layer and the lower layer contains the matting agent, and an amount of the matting agent in the upper layer is equal or more than an amount of the matting agent in the lower layer.

2. The decorative material of claim 1 , wherein the matting agent has a particle diameter of about 0.9 times a thickness of the gloss-adjusting layer with lower gloss.

3. The decorative material of claim 1 , wherein the matting agent comprises an inorganic material.

4. The decorative material of claim 1 , wherein the matting agent has a particle diameter of 2 μm or more and 15 μm or less.

5. The decorative material of claim 1 , wherein the matting agent is added in an amount of 5 parts by mass or more and 40 parts by mass or less relative to 100 parts by mass of a resin composition that constitutes the gloss-adjusting layer to which the matting agent is added.

6. The decorative material of claim 1 , wherein the matting agent is also added to the gloss-adjusting layer having higher gloss.

7. The decorative material of claim 1 , wherein the particle diameter of the matting agent is 0.2 times or more the thickness of the gloss-adjusting layer to which the matting agent is added.

8. The decorative material of claim 1 , wherein the amount of the matting agent in the upper layer is more than the amount of the matting agent in the lower layer.

9. A decorative material comprising:
a first gloss-adjusting layer provided on a substrate, and
a second gloss-adjusting layer partially provided on the first gloss-adjusting layer,
and having gloss that is different from that of the first gloss-adjusting layer;
with a matting agent added to, of the first gloss-adjusting layer and the second gloss-adjusting layer, the one with lower gloss, where the matting agent has a particle diameter of about 0.9 times a thickness of the gloss-adjusting layer with lower gloss, the matting agent is silica, the particle diameter of the matting agent is from 2 μm to 15 μm.

10. The decorative material of claim 9 , wherein a glossiness of the decorative material when observed at 85° is 8.5 or greater.

11. The decorative material of claim 9 , wherein the glossiness of the decorative material when observed at 85° is from 8.5 to 9.0.

12. The decorative material of claim 9 , wherein the particle diameter is from 2 μm to 12 μm.
