(57) [Summary] [Structure] A. An ultraviolet-curable resin obtained by reacting a reaction product of an epoxy resin and an unsaturated monocarboxylic acid with a saturated or unsaturated polybasic acid anhydride, B. A photopolymerization initiator, C.I. Diluent, D.I. Ammonia and / or amines, E. A thermosetting epoxy compound and F.I. An aqueous liquid resist ink composition containing water, which can be developed with a dilute alkaline aqueous solution. [Effect] While maintaining the resolution, solvent resistance, plating resistance, etc. of the conventional liquid resist ink, the above environmental problems, It can contribute to the improvement of work environment problems and reduce the burden on manufacturing equipment, transportation and fire protection. |
