<P>PROBLEM TO BE SOLVED: To provide an alkali-soluble radiation-sensitive resin and a composition containing the same. <P>SOLUTION: The photopolymerizable unsaturated resin is expressed by general formula (1) (X is a bifunctional aromatic epoxy acrylic acid derivative; (n) is an integer of 1-20; Y is a residue obtained by removing an acid anhydride group from a dicarboxylic acid anhydride; and Z is a residue obtained by removing acid anhydride groups from a tetracarboxylic acid dianhydride), has a number-average molecular weight of ≥1,000 and is produced by reacting the dicarboxylic acid anhydride and the tetracarboxylic acid dianhydride at a molar ratio of 1:99 to 65:35. The invention further provides an alkali-soluble radiation- sensitive resin composition containing the resin. The coating film produced from the composition has excellent properties such as heat-resistance, transparency, exposure-developing property and chemical resistance. <P>COPYRIGHT: (C)2003,JPO |
