PURPOSE:To obtain a composition capable of developing with a diluted alkali water solution, excellent in resolving property, solvent resistance and plating resistance and useful for printed circuit boards, etc., by including a specific ultraviolet ray-curable resin, a photopolymerization initiator, a diluent, ammonia, etc., a thermosetting epoxy compound and water. CONSTITUTION:The composition contains (A) an ultraviolet ray curable resin obtained by reacting a reactional product of an epoxy resin and an unsaturated monocarboxylic acid with a saturated or unsaturated polybasic acid anhydride, (B) preferably 1-25 pts.wt. (based on 100 pts.wt. component A) photopolymerization initiator such as benzoin, (C) preferably 10-95wt.% (based on total amount of the composition) diluent such as ethanol, (D) preferably 0.5-1.1 chemical equivalent (based on total amount of carboxyl group in the composition) of ammonia and/or amines such as 2-dimethylaminoethanol, (E) a thermosetting epoxy compound and (F) preferably 4-95wt.% (based on total amount of the composition) water. |
