Claim Text:
1. A curable composition for imprints comprising a polymerizable compound (Ax-1) having maleimide structure(s) and a photo-polymerization initiator (B), wherein: the polymerizable compound (Ax-1) having maleimide structure(s) is a compound having two or more maleimide structures, or, a compound having a maleimide group and a polymerizable group other than maleimide group and being free from ester groups; the polymerizable compound (Ax-1) has at least one silicon atom; the at least one silicon atom is contained in a chain-like structure of the polymerizable compound (Ax-1); and the content of a polymer having a molecular weight of 2,000 or more, based on the mass of the composition excluding solvent, is 30% by mass or less.
