PHOTOCURABLE COMPOSITION AND MANUFACTURING METHOD FOR A MOLDED BODY HAVING A FINE PATTERN ON THE SURFACE

摘要

Disclosed are a photocurable composition that can be used to obtain a cured substance that is both mold releasable and has a high refractive index, and a method enabling manufacture of a molded body with a high refractive index and that has on the surface a fine pattern formed by precisely transferring the reverse pattern of a mold. The photocurable composition contains 61 to 90 wt% of a compound (A) that has a refractive index of 1.55 or higher at a wavelength of 589 nm prior to curing and has two or more (meth)acryloyloxy groups, 2 to 15 wt% of a compound (B) (excluding compound (A)) having fluorine atoms and one or more carbon-carbon unsaturated double bonds, 5 to 35 wt% of a compound (C) (excluding compound (B)) having one (meth)acryloyloxy group, and 1 to 12 wt% of a photopolymerization initiator (D) ((A) + (B) + (C) + (D) = 100 wt%).
