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

摘要

PROBLEM TO BE SOLVED: To provide an alkali-developing resin composition and alkali-developing photosensitive resin composition excellent in sensitivity, resolution, developing properties, adhesion and the like and forming precisely fine patterns.;SOLUTION: This alkali-developing resin composition comprises a photopolymerizable unsaturated compound obtained by adding an unsaturated monobasic acid to an epoxy resin (A) having a structure obtained by alternate-copolymerizing 1,1-bis(4'-epoxypropyloxyphenyl)-1-phenyl-1-cyclohexylmethane or a derivative thereof which is an epoxy compound and a polyhydroxy aromatic compound and further by esterifying the above-obtained adduct of the epoxy resin (A) with a polybasic acid anhydride.;COPYRIGHT: (C)2007,JPO&INPIT
