Abstract:
1. A curable composition for imprints, comprising at least one polymerizable monomer (A) and a photopolymerization initiator (B), wherein: the at least one polymerizable monomer comprises a polymerizable monomer having a viscosity at 25° C. of from 8 to 50 mPa·s; the at least one polymerizable monomer comprises a monofunctional (meth)acrylate compound having one (meth)acrylate group and a polyfunctional (meth)acrylate compound having two or more (meth)acrylate groups, with at least one of either said monofunctional (meth)acrylate compound or said polyfunctional (meth)acrylate compound being selected from the group consisting of nonanediol diacrylate, 4-cyanobenzyl acrylate, 1- or 2-naphthyl(meth)acrylate, 1- or 2-naphthylmethyl(meth)acrylate, o-, m- or p-benzenedi(meth)acrylate, and o-, m- or p-xylylenedi(meth)acrylate; and the content of the polymerizable monomer is 95% by mass or more, relative to all polymerizable monomers contained in the composition.
