DEVELOPING PROCESS METHOD AND DEVELOPING SOLUTION FOR PHOTOSENSITIVE LITHOGRAPHIC PRINTING PLATE BY WHICH STABILITY OR THE LIKE OF DEVELOPING SOLUTION IS IMPROVED

摘要

PURPOSE:To improve developing power and developing stability by forming a developing soln. of an aq. alkaline soln. contg. a fluorine-contg. surfactant having a cationic group. CONSTITUTION:The developing soln. is formed of the aq. alkaline soln. contg. the fluorine-contg. surfactant having the cationic group. The cationic group in the fluorine-contg. surfactant having the cationic group is exemplified by ammonium, phosphonium, sulfonium, etc., and the surfactant is exemplified by compds. such as perfluoroalkyl trialkyl ammonium salt, etc., of perfluorobutyl trimethylammonium, etc., and includes further amphoteric surfactants having a cationic group and anionic group such as carboxylic acid. The content of the surfactant is preferably in a 0.001-5wt.% range, more preferably 0.01-5wt.% range, more particularly preferably 0.05-1wt.% The developing soln. having both the excellent developing power and development stability is thereby obtd.
