PURPOSE:To obtain good visible image developability by forming a primer layer as a layer which is coated with a compsn. contg. a specific compd. and photopolymn. initiator and is then photocured. CONSTITUTION:The primer layer is the layer formed by coating the surface of a substrate with the compsn. contg. the compd. having at least the two constitutional units expressed by formula I and having no arom. group and the photopolymn. initiator, then curing the compsn. by light. In the formula, R denotes a hydrogen atom or -(CH2)nCH3 group, where n denotes 0 to 8 integer. The compd. is incorporated preferably at 20 to 95wt.% into the primer layer. The photopolymn. initiator is incorporated preferably at 1 to 10wt.% into the primer layer. The good visible image developability is obtd. in this way. |
