Abstract:
A curable composition for imprinting satisfies the following A to C: A: the curable composition includes a polyfunctional polymerizable compound having a polymerizable group equivalent of 150 or higher; B: the curable composition includes a photopolymerization initiator; and C: the curable composition satisfies at least one of a condition that the content of an ultraviolet absorber in which the light absorption coefficient at a maximum emission wavelength of an irradiation light source is 1/2 or higher of the light absorption coefficient of the photopolymerization initiator is 0.5 to 8 mass % with respect to non-volatile components or a condition that the content of a polymerization inhibitor is 0.1 to 5 mass % with respect to the non-volatile components. The non-volatile components refer to components in the curable composition for imprinting other than a solvent.
