Patent ID: 6995193

Claim:
A photocurable composition comprising: (A) a compound which has a polymerizable unsaturated bond and gives a homopolymer having a glass transition point within the range of 0-100° C.; (B) a compound which has an unsaturated bond and is copolymerizable with the compound (A); (C) a compound having at least one cationically polymerizable group in a molecule; (D) a polymerization catalyst which initiates polymerization of the compounds (A) and (B) upon exposure to a radiation; and (E) a cationic polymerization catalyst which initiates cationic polymerization of the cationically polymerizable group in the compound (C) upon exposure to a radition; wherein said compound (B) contains a compound (B1) having at least one (meth)acryloyl group and at least one hydroxyl group per molecule and a compound (B2) having an unsaturated bond that is copolymerizable with the compound (B1).
