PURPOSE:To enhance storage stability by preparing a photosensitive compsn. of an additionally polymerizable unsatd. monomer, a binder, a photopolymn. initiator, and a P-contg. inorg. acid, in an amt. of 0.01-50wt% of said monomer. CONSTITUTION:The photosensitive compsn. consists of (a) an additionally polymerizable monomer, such as ethylene glycol methacrylate; (b) a binder, such as a copolymer of methyl (meth)acrylate/(meth)acrylic acid; (c) a photopolymn. initiator, and (d) a P-contg. inorg. acid in an amt. of 0.01-50wt% of said monomer. Said photosensitive compsn. used for the photosensitive lithographic printing plate especially exhibits superior performance, and as its support, dimensionally stable plate is suitable. |
