Developing solution composition

Abstract

Abstract PURPOSE:To enhance performance of developing an image forming material contg. a photosensitive resin contg. unsatd. double bonds adjacent to an aromatic ring and phenolic hydroxyl groups in a photosensitive layer by using an aq. alkaline soln. contg. a specified org. solvent. CONSTITUTION:Said aq. developing soln. compsn. contains at least org. solvent selected from benzyl alcohol, alpha-methylbenzyl alcohol, ethylene glycol monobenzyl ether, and ethylene glycol monophenyl ether; and an alkaline agent. A sufficient content of org. solvent in the developing soln. compsn. is 1wt%, and it is preferable to use the solvent in an amt. of <=20wt% from the view points of developing operability, safety and sanitariness in operational environment, air pollution control, etc. As the alkaline agent, inorg. alkali, such as, sodium silicate, potassium carbonate, or ammonia, and org. amine, such as monoethanol amine or ethylenediamine, can be enumerated.
