Claims18
A photocurable composition comprising a (meth)acrylic monomer component and a photopolymerization initiator,
- wherein an adhesive force of a cured product is less than or equal to 1.5 N, and a rupture elongation of the cured product is greater than or equal to 20%,
- wherein the (meth)acrylic monomer component contains a (meth)acrylic monomer (A) having two (meth)acryloyl groups, and a (meth)acrylic monomer (B) having one (meth)acryloyl group, and
- wherein at least one of the following (a) or the following (b) is satisfied:
- (a) the (meth)acrylic monomer (A) includes a (meth)acrylic monomer (A-1), in which a molecular weight per one (meth)acryloyl group is greater than or equal to 300 g/mol and is less than or equal to 600 g/mol, and contains a (meth)acrylic monomer (A-2), in which a molecular weight per one (meth)acryloyl group is greater than 600 g/mol and is less than or equal to 15000 g/mol, or
- (b) the (meth)acrylic monomer (B) includes a (meth)acrylic monomer (B-1) having two aromatic rings and contains a (meth)acrylic monomer (B-2) having one aromatic ring.
