Abstract

Provided is a laminate including a plasticizer-containing layer and an ink layer and having excellent adhesion between the plasticizer-containing layer and the ink layer and excellent low-temperature impact resistance, and a radiation curable ink.

Claims (12)

1 . A laminate comprising

a plasticizer-containing layer; and

an ink layer comprising a cured product of a radiation curable ink,

the radiation curable ink comprising (A) a radiation curable polymerizable monomer having a (meth)acryloyl group and a nitrogen-containing heterocyclic structure; (B) at least one type selected from the group consisting of i) a radiation curable polymerizable polyfunctional (meth)acrylate oligomer and ii) a radiation curable polymerizable polyfunctional (meth)acrylate monomer; and (C) at least one type selected from the group consisting of i) a radiation curable polymerizable monofunctional (meth)acrylate monomer having a linear alkyl group and ii) a radiation curable polymerizable monofunctional vinyl monomer having a linear alkyl group,

wherein a content of the component (A) is greater than 10 parts by mass based on 100 parts by mass of the radiation curable resin component;

a content of the component (B) is greater than 15 parts by mass based on 100 parts by mass of the radiation curable resin component, and

a content of the component (C) is greater than or equal to 1 part by mass based on 100 parts by mass of the radiation curable resin component.

2 . The laminate according to claim 1 , comprising a bifunctional urethane (meth)acrylate oligomer as the component (B).

3 . The laminate according to claim 1 , comprising a trifunctional urethane (meth)acrylate oligomer as the component (B).

4 . The laminate according to claim 1 , wherein the number of carbon atoms in the linear alkyl group is greater than or equal to 6.

5 . The laminate according to claim 1 , wherein the component (A) is at least one type selected from the group consisting of (meth)acryloyl morpholine, N-vinyl-ε-caprolactam, 5-methyl-3-vinyl-1,3-oxazolidin-2-one, and 1-vinylimidazole.

6 . The laminate according to claim 1 , wherein a plasticizer in the plasticizer-containing layer is at least one type selected from the group consisting of adipic acid-based plasticizer and phthalic acid-based plasticizer.
