Abstract

Provided are a decorative film including a base film, and a metal-containing layer which contains tabular metal particles on one surface of the base film; and a decorative molded body.

First claim

What is claimed is:

1. A decorative film comprising:
a base film; and
a metal-containing layer which contains tabular metal particles, on one surface of the base film,
wherein the metal-containing layer further contains a binder resin and at least one of a polymerizable compound containing a radically polymerizable unsaturated group or a cured product of the polymerizable compound containing a radically polymerizable unsaturated group, and
wherein the polymerizable compound contains at least one selected from the group consisting of a polymerizable compound containing at least five ethylenically unsaturated groups, a urethane (meth)acrylate compound, ethoxylated bisphenol A diacrylate, tricyclodecanediol di(meth)acrylate and a polymerizable compound containing an alkylene oxide group having 2 or 3 carbon atoms.

2. The decorative film according to claim 1 ,
wherein the thickness of the metal-containing layer is 1 μm or greater.

3. The decorative film according to claim 1 , further comprising:
a colored layer which contains a colorant other than the tabular metal particles on a surface of the metal-containing layer opposite to a side where the base film is provided.

4. The decorative film according to claim 3 ,
wherein the colored layer further contains at least one selected from a polymerizable compound containing a radically polymerizable unsaturated group or a cured product of the polymerizable compound containing a radically polymerizable unsaturated group.

5. The decorative film according to claim 1 ,
wherein the base film contains 60% by mass or greater of an acrylonitrile/butadiene/styrene copolymer resin with respect to a total amount of the resin contained in the base film.

6. The decorative film according to claim 1 , wherein an average thickness of the tabular metal particles is from 0.001 μm to 1 μm.

7. The decorative film according to claim 6 , wherein an aspect ratio of the tabular metal particles is from 40 to 1000.

8. The decorative film according to claim 6 , wherein an average major axis diameter of the tabular metal particles is from 1 μm to 100 μm.

9. The decorative film according to claim 6 , wherein a content of the tabular metal particles in the metal-containing layer is from 5% by mass to 40% by mass with respect to a total mass of the metal-containing layer.

10. The decorative film according to claim 1 , which is used for insert molding.

11. A decorative molded body comprising:
a molded base material; and
the decorative film according to claim 1 on the molded base material.

12. The decorative film according to claim 1 , wherein a content of the binder resin in the metal-containing layer is from 20% by mass to 90% by mass with respect to the total mass of the metal-containing layer.

13. The decorative film according to claim 1 , wherein a content ratio between the polymerizable compound and the binder resin is 0.20 or greater.
