    Abstract: PURPOSE: To ensure satisfactory stability in a rolled state even at the time of storage of a dry film resist over a long period of time by allowing a specified N-vinylamide copolymer or a polyamide additive to exist in a photopolymerizable recording layer. CONSTITUTION: The top of a carrier having dimensional stability is coated with a photopolymerizable recording layer developable with an aq. alkali soln. and contg. a polymer binder, at least one kind of ethylenic unsatd. photopolymerizable compd. and at least one kind of photoinitiator or further contg. other additives and/or auxiliaries. In the recording layer, an N-vinylamide homopolymer, an N-vinylamide copolymer contg. >=50mol% N-vinylamide units in a polymerized state or a polyamide additive having 1,500-300,000g/mol mol.wt. exists by 0.2-6wt.% of the total amt. of the recording layer. Laminating is facilitated and stability in a rolled state can be improved even at the time of storage of a dry film resist over a long period of time.
