Zusammenfassung:	PURPOSE:To obtain a printing plate having high sensitivity, superior printing resistance, etc. and capable of being developed with water by forming a photosensitive layer contg. photosensitive polyester consisting of a specified aromatic dicarboxylic acid, a dicarboxylic acid having a sulfonate group, and a specified diol on a support. CONSTITUTION:A lithographic plate is manufactured by forming a photosensitive layer contg. photosensitive polyester on an Al substrate or the like. The polyester consists of 5-45mol% dicarboxylic acid units (a) represented by formulaI(where each of m and n is 0 or 1, and at least one of them is 1),
