ABSTRACT:
A positive type photosensitive resin composition comprising an alkali-soluble novolac resin and (A) a compound represented by the following general formula (I) and a compound represented by the following general formula (II) or (B) a compound represented by the following general formula (III) and a compound represented by the following general formula (IV), wherein the molar ratio of the compound represented by the general formula (I) to the compound represented by the general formula (II) is 6/4-9/1 or the molar ratio of the compound represented by the general formula (III) to the compound represented by the general formula (IV) is 1/9-9/1 and the total amount of the component (A) or (B) is 5-100 parts by weight per 100 parts by weight of the alkali-soluble novolac resin: ##STR1## wherein R.sub.1, R.sub.5, R.sub.8 and R.sub.10, which may be identical or different, represent alkyl groups, aryl groups or aralkyl groups; and R.sub.2, R.sub.3, R.sub.4, R.sub.6, R.sub.7, R.sub.9, R.sub.11 and R.sub.12, which may be identical or different, represent 1,2-naphthoquinonediazide-4-sulfonyl groups, 1,2-naphthoquinonediazide-5-sulfonyl groups or 1,2-benzoquinonediazide-4-sulfonyl groups. Said positive type photosensitive resin composition is excellent in both sensitivity and yield of residual film thickness.
