Abstract

Abstract A light-sensitive resin composition comprising a light-sensitive substance represented by the formula (A) shown below and an alkali-soluble resin: ##STR1## wherein R 1 to R 8 are independently hydrogen, a hydroxyl group, a halogen atom, an alkyl group, an alkoxy group, an aralkyl group, an aryl group, an amino group, a monoalkylamino group, a dialkylamino group, an acylamino group, an alkylcarbamoyl group, an arylcarbamoyl group, an alkylsulfamoyl group, an arylsulfamoyl group, a carboxyl group, a cyano group, a nitro group, an acyl group, an alkyloxycarbonyl group, an aryloxycarbonyl group, an acyloxy group, -OD, or ##STR2## (wherein R is hydrogen, or an alkyl group, and D is a 1,2-naphthoquinonediazido-5-sulfonyl group or a 1,2-naphthoquinonediazido-4-sulfonyl group); R 9 to R 12 are independently hydrogen or a lower alkyl group; and Z is oxygen or a single bond; provided that at least one of R 1 to R 8 is -OD or ##STR3##
