METHOD FOR DEVELOPING PHOTOSENSITIVE RESIN PLATE

摘要

PURPOSE:To increase the rate of development and to improve image reproducibility in a process for developing a photosensitive resin plate. CONSTITUTION:When a photosensitive resin plate with a layer of a photosensitive resin compsn. contg. a hydrophobic component and a hydrophilic component is developed, the unexposed part is processed with a developer having dissolving or dispersing ability to the hydrophilic component and contg. alkali metal ions so as to disperse the photosensitive resin compsn. in the unexposed part as particles of <=100mum particle diameter.
