Abstract
Abstract A resist image, which is excellent in adhesiveness and high in physicochemical strengths, can be obtained by using as a resist material a resin composition having such properties that when it is exposed to actinic rays, a latent image (cure-precursor) is formed therein, and when it is subjected to subsequent heating, only the latent image portion is selectively cured.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
A resist image-forming curable resin composition which comprises (A) an epoxy resin prepolymer having at least two epoxy groups per molecule and (B) a compound having in the molecule at least two groups represented by formulas (I) and/or (II), ##STR9## wherein R 1 , R 2 and R 3 are individually a hydrogen atom, an alkyl group or an aryl group, said compound (B) being: (a) a compound produced by the reaction of a polycarboxylic acid, polycarboxylic acid anhydride, polycarboxylic acid halide, polyamine or polyisocyanate with an alcohol represented by the formula (V): ##STR10## (b) a compound produced by polymerization of an ester of a monomeric ethylenically-unsaturated acid or an acid anhydride thereof and an alcohol of the formula (V): the ratio of said compound (B) to said epoxy resin prepolymer (A) being in the range 0.1 to 0.8 where said range is defined by the ratio of the sum of said groups (I) and/or (II) in compound (B) expressed in equivalents to the sum of said epoxy groups in compound (A).
Claim 2
Dependent Claim
