Filed: 1986-01-20
Abstract: PURPOSE:To improve developability, printing condition and developing speed by incorporating a prescribed amt. of a nonionic type surface active agent into a developing soln. and adjusting the pH thereof to a prescribed range. CONSTITUTION:The developing soln. into which the nonionic type surface active agent is incorporated at 0.001-10wt% and of which the pH is maintained in a 11.5-13.5 range is used in the case of commonly processing a negative type photosensitive lithographic printing plate and positive type photosensitive lithographic printing plate each having an image forming layer on a substrate. Adequate common development is executed by incorporating 0.1-10wt% org. solvent having <=10wt% solubility in water at 20 deg.C into said developing soln. The stable and good image is thus obtd. even if the development is executed at about twice higher speed than heretofore.
