Abstract

Disclosed is an active energy ray-curable resin the composition for plastic films which contains an oxetane compound, an epoxy compound, and at least one silicone compound selected from epoxy-modified silicones, fluorine-modified silicones, amino-modified silicones, (meth)acrylic-modified silicones, and polyether-modified silicones. The resin the composition has excellent printability such as gravure printability and flexographic printability and cures rapidly to attain high productivity. After curing, it gives a cured layer which excels in adhesion to the plastic base film and in toughness and has good recoatability. A plastic label using the resin the composition excels in surface scratch resistance and crumpling resistance. This label is hence useful especially as a label to be applied to plastic containers, metallic containers such as bottle cans.

Claims

1. Active energy ray-curable resin composition for a plastic film, comprising an oxetane compound, an epoxy compound, and at least one silicone compound selected from the group consisting of epoxy-modified silicones, fluorine-modified silicones, amino-modified silicones, (meth)acrylic-modified silicones, and polyether-modified silicones.

2. Active energy ray-curable resin composition for a plastic film, according to claim 1, wherein the resin composition comprises the oxetane compound and the epoxy compound in a weight ratio of 2:
