Photocurable composition which can form the hardened | cured material which is excellent in environmental characteristic and mold release property, and is excellent in the compatibility of a fluorine surfactant and another component, and has the fine pattern by which the inversion pattern of the mold was precisely transferred to the surface, and Provided is a method for producing a molded article having a uniform composition. As a photocurable composition for imprints which has a compound which has one or more (meth) acryloyloxy groups as a main component, the photocurable composition containing the following polymer (D). 20 to 45 mass% of units of CH 2 = C (R 11 ) -C (O) OQR f and CH 2 = C (R 21 ) -C (O) O- (CH 2 CH (R 22 ) O) n − polymers of H (number average molecular weight of 350 or less) 20 to 65 wt% of units and CH 2 = C (R 31) -C (O) OR 32 containing units of 5 to 40% by weight of, the weight average molecular weight of 1000 ~ 5000 (D). R 11, R 21, R 31 = hydrogen atom, a methyl group, and Q = 2-valent connecting group, polyfluoroalkyl of R f = C 1 -C 6 alkyl group, R 22 = and hydrogen atoms, n = 3 ~ 6, R 32 = Aliphatic hydrocarbon group having 2 to 15 carbon atoms. |
