Abstract:
1. A photocurable material for sealing, comprising (A) an oligomer having a weight average molecular weight of 10,000 to 30,000 and having a (meth)acryloyl group, (B) a (meth)acrylate monomer, and (C) a polythiol compound, wherein the (meth)acrylate (B) is contained in an amount of 5 to 100 parts by weight relative to 100 parts by weight of (A) the oligomer having a (meth)acryloyl group, and the ratio of the number of (meth)acryloyl groups contained in both of (A) the oligomer having a (meth)acryloyl group and (B) the (meth)acrylate monomer to the number of thiol groups contained in (C) the polythiol compound present in the photocurable material for sealing is 100:5n to 100:25n, but not inclusive of 100:5n, wherein n is the number of thiol groups per molecule of the polythiol compound.
