<p>PURPOSE:To obtain a soldering resist ink compsn. capable of dilution and development with water and giving a cured body excellent in characteristics. CONSTITUTION:This soldering resist ink compsn. is developable with water and contains a compd. (A) having a radical-polymerizable group and a tert. amino group in one molecule, a water-soluble org. acid (B) having one or more hydroxyl groups or ether bonds and two or more carboxyl groups in one molecule, a photopolymn. initiator (C) and a heat curing agent (D) selected from among epoxy resin, melamine resin and a blocked polyisocyanate compd. as essential components. A compd. having a radical-polymerizable group, an epoxy group and a/tert. amino group may be contained in place of the compd. A.</p> |
