Abstract
Provided are a highly-curable photosensitive composition capable of forming cured products that are less likely to undergo excessive mass loss even when heated; and a product of curing of such a photosensitive composition. The photosensitive composition includes photopolymerizable compounds (A) and an initiating agent (C), in which the photopolymerizable compounds (A) include a combination of a compound of a specific structure having a radically polymerizable group-containing group or a cationically polymerizable group-containing group and a polyfunctional compound different from the compound of a specific structure.

A photosensitive composition comprising:
- photopolymerizable compounds (A);
- and an initiating agent (C),
- the photopolymerizable compounds (A) including:
- a compound (A1) of Formula (A1):
- (Ra01—Xa01—Ra02)ma1—Ara01—C(═O)—Ara02—(Ra03—Xa02—Ra04)ma2 (A1)
- wherein Ara01 is an aromatic group having 6 or more and 12 or less carbon atoms, having a valence of ma1+1, and optionally substituted with one or more selected from the group consisting of an alkyl group having 1 or more and 5 or less carbon atoms, a cyano group, and a halogen atom, Ara02 is an aromatic group having 6 or more and 12 or less carbon atoms, having a valence of ma2+1, and optionally substituted with one or more selected from the group consisting of an alkyl group having 1 or more and 5 or less carbon atoms, a cyano group, and a halogen atom, Ra01 and Ra04 are each independently a radically polymerizable group-containing group or a cationically polymerizable group-containing group, Xa01 and Xa02 are each independently O or S, Ra02 and Ra03 are each independently an alkylene group, ma1 is an integer of 1 or more and 3 or less, and ma2 is an integer of 0 or more and 3 or less;
- and
- at least one additional photopolymerizable compound (A2) different from the compound (A1),
- the at least one additional photopolymerizable compound (A2) including a polyfunctional compound (A2-1) having two or more polymerizable groups,
- the initiating agent (C) being different from the compound (A1).
