Abstract (en)

[origin: EP1157829A1] The present invention relates to a lithographic printing plate in which images can be inscribed by laser beams, and which has high resolving power, high sensitivity, and the improved reservation stability, and relates to its image-producing method, and a photosenstitive composition which can preferably be used as an original plate for lithographic printing. The photosenstitive composition includes an aqueous resin composition including fine particles (a) of a resin having at least one neutralized anionic group and having a heat fusion property, and a water soluble resin (b) having at least one neutralized anionic group, wherein the water soluble resin (b) is included in a range of 1 to 30% by weight, relative to the total weight of the aqueous resin composition; and a substance (c) which absorbs light and generates heat.
