DEVELOPING METHOD FOR SENSITIVE MATERIAL INCLUDING DIAZO RESIN

摘要

PURPOSE:To prevent the generation of stain even when used for printing by obtaining a sensitive material in which anions of a diazo resin is specific, and developing the material in a specific condition and with a developer substantially not including an organic solvent. CONSTITUTION:A sensitive layer having a diazo resin and an alkali soluble swelling polymer compound is provided on a supporting body. And anions of the diazo resin are PF6<->, BF4<-> and an organic anion or a mixture of them. This sensitive material is developed at a pH of 8 to below 12 at 25 deg.C and with a developer substantially not including an organic solvent.
