Abstract:
To provide a photocurable composition with which a fine pattern molded product on which a fine pattern of a mold is highly precisely transferred can efficiently be produced.A photocurable composition comprising 100 parts by mass of a photocurable monomer (A), from 5 to 60 parts by mass of a colloidal silica (B) (solid content) having an average particle size of at most 200 nm, and from 0.1 to 10 parts by mass of a photopolymerization initiator (C), wherein the photocurable monomer (A) comprises a multifunctional monomer (A1) having at least 3(meth)acryloyloxy groups in one molecule and a bifunctional monomer (A2) having two (meth)acryloyloxy groups in one molecule, at least one compound belonging to the multifunctional monomer (A1) or the bifunctional monomer (A2) has a hydroxy group, and the ratio of the total amount (mol) of hydroxy groups to the total amount (mol) of the multifunctional monomer (A1) and the bifunctional monomer (A2) is at least 10%.
