Abstract
PURPOSE:To omit a step of irradiating an full light to the title plate, and to improve the developing latitude such as the image reproducibility and the solvent resisting property, etc., and to stabilize the performance of the title plate, by incorporating a specified beta-gamma unsatd. carboxylic acid in a photosensitive layer and a silicone rubber layer, respectively. CONSTITUTION:The title plate laminates a supporting body, a photosensitive layer contg. quinone diazide compd. and a silicone rubber layer, in this order, and the photosensitive layer and the silicone rubber layer contain the beta-gamma-unsatd. carboxylic acid shown by the formula wherein R1-R5 are each hydrogen atom, 1-15C alkyl, 6-15C aryl or 6-15C aralkyl group. Thus, in spite of the fact that the step of projecting the full light to the title plate to decompose partially the quinone diazide compd., in the process step of the title plate is omitted, the development latitude such as the image reproducibility, the solvent resisting property and the developing property of the title plate is improved, and at the same time, the performance of said plate is stabilized thereby improving the productibity and the characteristics of the planographic printing plate with out using water.
