POSITIVE-ACTING PHOTOSENSITIVE COMPOSITION AND HARDENED MATERIAL THEREOF

摘要

A positive-acting photosensitive composition containing: (A) a silanol-group-containing polysiloxane compound having a structure obtained by subjecting a compound represented by formula (1) and a compound represented by formula (2) to hydrolysis and a condensation reaction; (B) a compound having at least two epoxy-containing organic groups; (C) a diazonaphthoquinone; and (D) an organic solvent. R1 represents a C1-4 alkyl group or the like, R2 represents a C2-10 divalent hydrocarbon group, R3 represents a C2-10 divalent saturated aliphatic hydrocarbon group, and X represents a group (see description for details) represented by general formulas (3-5). Furthermore, m, n and p represent numbers in a manner such that the following are satisfied: m:n:p=1:2.1-12:1-6, and m+n+p=3-6. R4 represents a C1-4 alkyl group or the like, R5 represents a C1-4 alkyl group, and a represents 1-2.
