Claims
- 1. A positive type photosensitive resinous composition which comprises an a admixture of photosensitive 1,2 quinone diazide compound and an acrylic resin obtained by polymerizing 3 to 80 parts by weight of an acrylic monomer represented by the formula: ##STR24## wherein R.sub.1 is hydrogen or a methyl group, R.sub.2 is an aliphatic hydrocarbon of 2 to 10 carbon atoms, an alicyclic hydrocarbon of 6 to 7 carbon atoms or an aromatic hydrocarbon of 6 carbon atoms, A is a repeating unit of the formula: ##STR25## in which R.sub.3 is ethylene or propylene, R.sub.4 is alkylene of 2 to 5 carbon atoms, k an l each is an average number of the parenthesized group and k is 1 to 10 and 1 is 2 to 50, or the formula: ##STR26## wherein R.sub.6 is hydrogen or a methyl group, R.sub.7 is an aliphatic hydrocarbon of 5 to 10 carbon atoms, an alicyclic hydrocarbon or 6 to 7 carbon atoms or an aromatic hydrocarbon of 6 to 13 carbon atoms, R.sub.8 is an aliphatic hydrocarbon of 1 to 30 carbon atoms, an aromatic hydrocarbon of 6 to 13 carbon atoms or such hydrocarbon substituted with a member selected from the group consisting of vinyl, allyl, ether, ester and carbonyl groups, B is a ##STR27## in which m and n each is 0 or 1, D is a repeating unit represented by the formula: ##STR28## R.sub.9 is ethylene or propylene, R.sub.10 is alkylene of 2 to 7 carbon atoms, R.sub.11 is alkylene of 2 to 5 carbon atoms, p and q each is an average number of the parenthesized repeating unit and p is 1 to 10 and q is 2 to 50, E is a carboxylic acid or sulfonic acid group, and 97 to 20 parts by weight of another .alpha.,.beta.-ethylenically unsaturated copolymerizable monomer, the solid weight ratio of said acrylic resin to quinone diazide compound being 100:5 to 100:150.
