Abstract
A photocurable material for sealing including (A) an oligomer having a weight average molecular weight of 10,000 to 30,000 and having (meth)acryloyl group(s), (B) a (meth)acrylate monomer, (C) a polythiol compound, and optionally (D) a carbodiimide compound enables the provision of a sealing material that has high compression recovery performance, high tensile strength and excellent flexibility, can have low hardness if required, and therefore has excellent sealing properties including air-tightness performance and water-proof performance and undergoes the formation of little surface tacks and the like.
