Abstract

A decorative material includes a base material, a first cover layer, and a second cover layer. The first cover layer is laminated on the base material and covers the base material. The first cover layer is made of opaque synthesis resin. The second cover layer is laminated on the first cover layer and covers the first cover layer. The second cover layer is made of chromatic and transparent synthesis resin. The first cover layer contains first coloring pigment and bright pigment. The first coloring pigment has no luster. The bright pigment has luster. The second cover layer contains second coloring pigment. The second coloring pigment has no luster.

First claim

The invention claimed is:

1. A decorative material comprising:
a base material;
a bonding layer;
a first cover layer that is laminated on the base material using the bonding layer, the bonding layer being positioned in between the first cover layer and the base material, and the first cover layer covering the base material and being made of opaque synthesis resin; and
a second cover layer that is laminated on the first cover layer, covers the first cover layer, and is made of chromatic and transparent synthesis resin, wherein
the first cover layer contains
a first coloring pigment having no luster, and
a bright pigment having luster, and

the second cover layer contains
a second coloring pigment having no luster, and
does not contain the bright pigment,

wherein, in the second cover layer, the difference between an L* value in an L*a*b* color system of JIS Z 8781-4 for light reflected toward a virtual straight line orthogonal to a front face of the decorative material by 15° from regular reflected light having a reflection angle of 45° with respect to the virtual straight line through reflection of light at the front face of the decorative material at an incident angle of 45° with respect to the virtual straight line and the L* value for light reflected toward the virtual straight line by 45° from the regular reflected light is set to be equal to or larger than 32.9.

2. The decorative material according to claim 1 , wherein
the first cover layer contains a first amount of the first coloring pigment per unit volume, and
the second cover layer contains a second amount of the second coloring pigment per unit volume, the second amount being smaller than the first amount.

3. The decorative material according to claim 1 , wherein
the first cover layer contains a third amount of the first coloring pigment per unit area, and
the second cover layer contains a fourth amount of the second coloring pigment per unit area, the fourth amount being smaller than the third amount.

4. The decorative material according to claim 1 , wherein, in the second cover layer, an L* value in an L*a*b* color system of JIS Z 8781-4 is set to be higher than the L* value of the first cover layer.

5. The decorative material according to claim 2 , wherein, in the second cover layer, an L* value in an L*a*b* color system of JIS Z 8781-4 is set to be higher than the L* value of the first cover layer.

6. The decorative material according to claim 3 , wherein, in the second cover layer, an L* value in an L*a*b* color system of JIS Z 8781-4 is set to be higher than the L* value of the first cover layer.
