Abstract

A decorative material with improved release properties and scratch resistance. A decorative material according to a mode of the present invention includes a first gloss control layer provided to a front surface and a second gloss control layer provided on part of the first gloss control layer. The first gloss control layer contains a gloss control agent comprised of a hydrophilic inorganic material and a silicone-based release agent having a reactive terminal group. The reactive terminal group of the silicone-based release agent preferably has at least one of a hydroxyl group and an amino group. The second gloss control layer contains a silicone-based release agent having a reactive terminal group, and the reactive terminal group of the silicone-based release agent has at least one of an acryloyl group and a methacryloyl group.

First claim

What is claimed is:

1. A decorative material, comprising:
a first gloss control layer provided to a front surface and a second gloss control layer provided on part of the first gloss control layer; and,
the first gloss control layer containing a gloss control agent comprised of a hydrophilic inorganic material and a silicone-based release agent having a reactive terminal group.

2. The decorative material of claim 1 , wherein the reactive terminal group of the silicone-based release agent has at least one of a hydroxyl group and an amino group.

3. The decorative material of claim 1 , wherein an additive amount of the silicone-based release agent to the first gloss control layer is formulated such that an active component of the silicone-based release agent is in a range of 1 part by mass or more and 6 parts by mass or less relative to 100 parts by mass of solid content included in the first gloss control layer.

4. The decorative material of claim 1 , wherein:
a resin component included in the first gloss control layer contains a main material that is a mixture of a urethane-based thermosetting resin containing a polyol and an isocyanate with an ionizing radiation-curable resin having an acryloyl group or a methacryloyl group; and,
a content of the urethane-based thermosetting resin is in a range of 3 parts by mass or more and 100 parts by mass or less relative to 100 parts by mass of the ionizing radiation-curable resin.

5. The decorative material of claim 1 , wherein:
the second gloss control layer contains a silicone-based release agent having a reactive terminal group; and,
the reactive terminal group of the silicone-based release agent has at least one of an acryloyl group and a methacryloyl group.

6. The decorative material of claim 5 , wherein an additive amount of the silicone-based release agent to the second gloss control layer is formulated such that an active component of the silicone-based release agent is in a range of 0.5 parts by mass or more and 5 parts by mass or less relative to 100 parts by mass of solid content included in the second gloss control layer.

7. The decorative material of claim 1 , wherein:
a resin component included in the second gloss control layer contains a main material that is a mixture of a urethane-based thermosetting resin containing a polyol and an isocyanate with an ionizing radiation-curable resin having an acryloyl group or a methacryloyl group; and,
a content of the urethane-based thermosetting resin is 25 parts by mass or less relative to 100 parts by mass of the ionizing radiation-curable resin.

8. The decorative material of claim 1 , wherein a resin component included in the second gloss control layer has a main material that is an ionizing radiation-curable resin having an acryloyl group or a methacryloyl group.

9. The decorative material of claim 4 , wherein the ionizing radiation-curable resin having an acryloyl group or a methacryloyl group has a number average molecular weight in a range of 300 or more and 5,000 or less.

10. The decorative material of claim 9 , wherein the ionizing radiation-curable resin having an acryloyl group or a methacryloyl group has a number average molecular weight in a range of 300 or more and 1,500 or less.

11. The decorative material of claim 1 , wherein:
the decorative material includes a patterned ink layer under the first gloss control layer; and,
the second gloss control layer is formed in a portion overlapping a design pattern of the patterned ink layer as viewed perpendicularly to a front surface, and the design pattern of the patterned ink layer matches with glossiness of the second gloss control layer.

12. The decorative material of claim 1 , wherein:
the decorative material includes a patterned ink layer under the first gloss control layer; and,
the second gloss control layer is formed in a portion other than a portion right above a design pattern of the patterned ink layer, and the design pattern of the patterned ink layer matches with glossiness of the first gloss control layer.
