PURPOSE:To facilitate removal of the unexposed and uncured photosensitive layer of a photosensitive material and to reduce aged deterioration by using the developing soln. compsn. contg. an anionic surfactant, alkali metal or ammonium nitrate. CONSTITUTION:As the anionic surfactant, e.g., alkyl sulfate salt or alkylbenzenesulfonate, alone or combination of 2 or more, is used in a concn. of 0.1- 10wt%, far preferably, 0.1-5wt%. As the alkali metal or ammonium nitrate, sodium or potassium nitrate, or the like is used, preferably, in an amt. of 0.05- 3wt%, far preferably, 0.1-1.0wt%. An org. solvent, an alkali agent, alkali metal or ammonium sulfite, and/or a nonionic surfactant may be added further to the developing soln. compsn.. |
