Abstract

A photosensitive resin composition contains a photosensitive resin comprising recurring units of formula (1) and having a Mw of 1,300-11,000 and 20-5,000 ppm of a tertiary amine compound of formula (2). ##STR1## R is hydrogen or a 1,2-naphthoquinonediazido-5-sulfonic acid residue, the content of 1,2-naphthoquinonediazido-5-sulfonic acid residue in R is 3-27 mol %, and m is a number from 0 to 3, X is a C.sub.6-20 alkyl, aryl or aralkyl group, Y and Z each are a C.sub.1-20 alkyl group. The composition is improved in sensitivity stability and adhesion to substrates and eliminates the risk of causing corrosion of metal substrates.
