摘要： A positive type photosensitive image-forming material for use with an infrared laser is provided. The material includes a substrate, a layer (A) containing not less than 50% by weight of a copolymer which contains, as a copolymerization component, not less than 10% by mol of at least one of the following monomers (a-1) to (a-3), wherein (a-1) is a monomer having in the molecule a sulfonamide group wherein at least one hydrogen atom is linked to a nitrogen atom, (a-2) is a monomer having in the molecule an active imino group represented by the following general formula (I): and (a-3) is a monomer selected from acrylamide, methacrylamide, acrylate, methacrylate and hydroxystyrene, which respectively have a phenolic hydroxyl group; and a layer (B) containing not less than 50% by weight of an aqueous alkali solution-soluble resin having a phenolic hydroxyl group. The layer (A) and the layer (B) are laminated on the substrate in that order. At least the layer (B) contains a compound which generates heat upon absorbing light. The image-forming material has excellent stability of sensitivity with regard to concentration of a developing solution, i.e., has excellent development latitude.

摘要： Disclosed is a positive-type photosensitive composition comprising in predetermined blending proportions a substance which generates heat upon absorbing light, a resin which has phenolic hydroxyl groups and is soluble in an aqueous alkaline solution, and a copolymer comprising 10 mol % or more of at least one of acrylic derivatives having a sulfonamide group as a component for copolymerization. The above-described composition is designed for use with an infrared laser in a direct plate making process as a composition advantageous in that the problems of insufficient image forming ability and insufficient solvent resistance of the resin, which has phenolic hydroxyl groups and is soluble in an aqueous alkaline solution, are solved, and in that the range of locations where the photosensitive composition may be handled are not limited, and further in that the sensitivity of the photosensitive composition to the concentration of the developing solution is stable, i.e., there is a broad latitude in development.
