Patent ID: 6844029

Claim:
A photocurable primer composition containing (A) an acrylic resin having through an urethane linkage a polymerizable unsaturated group on its side chain and containing the polymerizable unsaturated group in an amount of 0.2 to 2.0 mol/kg in a solid content of the resin (A), (B) an urethane (meth)acrylate oligomer containing at least one polymerizable unsaturated group in one molecule and prepared by reacting a compound (e) containing at least two isocyanate groups in one molecule, a hydroxyl group-containing polymerizable unsaturated monomer (f) and a monohydric alcohol (g), (D) an extender pigment in an amount of 1 to 300 parts by weight per 100 parts by weight of a total resin solid content of the components (A), (B) and (C) in the primer composition, and (E) a photopolymerization initiator.
