Abstract:
A photocurable composition for imprint at least has a polymerizable compound (A) and a photopolymerization initiator (B), in which the polymerizable compound (A) contains 20% by weight or more of a multifunctional (meth)acrylic monomer and the glass transition temperature of a photocured substance of the photocurable composition is 90° C. or more.
