Epoxy resins, alkali-developable resin composition and alkali-developable photosensitive resin composition

摘要

PROBLEM TO BE SOLVED: To provide an alkali developable resin composition having excellent sensitivity, resolution, adhesion or the like, and enabling a fine pattern to be formed in good accuracy; and to provide an alkali-developable photosensitive resin composition.;SOLUTION: The epoxy resin has a structure obtained by adding a polycarboxylic acid to an epoxy compound represented by general formula (I) (wherein, Cy is a cycloalkyl group; X is a hydrogen atom, a phenyl group or a cycloalkyl group; Y and Z are each an alkyl group, an alkoxy group, an alkenyl group or a halogen atom; n is a number of 0-10; p is a number of 0-4; and r is a number of 0-4).;COPYRIGHT: (C)2007,JPO&INPIT
