Abstract
Abstract A positive type photosensitive resin composition comprising an alkali-soluble novolac resin and (A) a compound of formula (I) and a compound of formula (II) or (B) a compound of formula (III) and a compound of formula (IV), the molar ratio of compound (I) to compound (II) being from 6:4 to 9:1, the molar ratio of compound (III) to compound (IV) being from 1:9 to 9:1 and the total amount of component (A) or (B) being from 5 to 100 parts by weight per 100 parts by weight of the alkali-soluble novolac resin: wherein R 1 , R 5 , R 8 and R 10 , which may be the same or different, represent alkyl, aryl or aralkyl groups; and R 2 , R 3 , R 4 , R 6 , R 7 , R 9 , R 11 and R 12 , which may be the same or different, represent 1,2-naphthoquinonediazide-4-sulfonyl, 1,2-naphthoquinonediazide-5-sulfonyl or 1,2-benzoquinonediazide-4-sulfonyl groups. This positive type photosensitive resin composition has excellent sensitivity and yield of residual film thickness.
