(57) [Summary] [PROBLEMS] To exhibit high-contrast image formability without lowering sensitivity, and to have a wide range of burn-out, white light safety and development tolerance, and even when subjected to a large amount of processing, the developer becomes sludge. No positive photosensitive composition is obtained. A least (1) 20 to 60 mol% addition-polymerizable monomer having a fluoroaliphatic group in which a hydrogen atom is substituted with a fluorine atom in the side chain and (2) -SO 2 NH 2, -SO 2 NH -, -SO 2 NHCOO-, -CONHSO 2- , -CONHSO 2 NH-, -NHCONHSO 2- And a polymer compound containing, as a copolymerization component, 30 to 70 mol% of an addition-polymerizable monomer having at least one acidic hydrogen atom substituent selected from -CONHC0-. |
