<p>A photosetting liquid ink composition developable with a dilute alkaline aqueous solution and comprising (A) a resin curable with an activated energy ray, obtained by the reaction of a saturated or unsaturated polybasic acid anhydride with a product of the reaction of a novolak type epoxy compound and an unsaturated monocarboxylic acid, (B) a photopolymerization initiator, and (C) a diluent can be used for the production of an etching resist or a solder resist in the manufacture of a printed circuit. This composition, when combined with a thermosetting component, produces a photosetting and thermosetting liquid ink composition.</p> |
