PROBLEM TO BE SOLVED: To provide a stripper to strip a cured film of a photopolymerizable composition formed on a substrate by irradiation of light from the substrate, and in particular, to provide the stripper for the cured film which suppresses changes in the colors of the plated part or the substrate even when severe conditions for stripping are adopted for a resist film firmly hardened by a large quantity of exposure light. SOLUTION: The stripper is used to strip the cured film from a substrate, the cured film obtained by applying or laminating a photopolymerizable composition to be developed with an alkali aqueous solution and then curing the composition with active rays. The composition comprises (a) water, (b) water-soluble alkanol amine, (c) quaternary ammonium hydroxide and (d) basic triazoles or tetrazoles. COPYRIGHT: (C)2003,JPO |
