PHOTOCURABLE COMPOSITION, AND METHODS USING THE SAME FOR FORMING CURED PRODUCT PATTERN AND FOR MANUFACTURING OPTICAL COMPONENT, CIRCUIT BOARD AND IMPRINTING MOLD

Document Type and Number:

WIPO Patent Application WO/2016/031175

Kind Code:

A1

Abstract:

A photocurable composition contains a polymerizable compound (A) satisfying OA = NA/(NC,A - NO,A), wherein NA, NC,A and NO,A represent the total number of atoms, the number of carbon atoms, and the number of oxygen atoms, respectively, in (A); and a non-polymerizable component (E) containing at least one compound (X) including a photopolymerization initiator (B), in a proportion of 10% to 50% relative to the total weight of (A) and (E). The component (E) has a weight average molecular weight of 250 or less. The compound (X) satisfies OX = NX/(NC,X - NO,X). NX, NC,X and NO,X represent the total number of atoms, the number of carbon atoms, and the number of oxygen atoms, respectively, in the corresponding compound (X). The composition satisfies: OA - OE > 1.00; and OAE < 3.40. OE and OAE represent the molar fraction weighted averages of OX's and of OA and OE, respectively.
