PURPOSE: To obtain an aqueous thermosetting resin composition having excellent merits of isocyanate curing type, having eliminated defects.
CONSTITUTION: An aqueous thermosetting resin composition comprises (A) an epoxy resin obtained by reacting (a) a compound containing one or more vinyl groups and one epoxy group in one molecule with (b) at least one of a polybasic acid anhydride, a polybasic acid, an acid end polymer and a carboxylic acid-containing polymer and (C) at least one of a compound containing one or more active hydrogen atoms to give a vinyl group-containing resin and further epoxidizing the resin, (B) a resin containing a hydroxyl group and a cationic group such as a resin prepared by reacting an epoxy group of a polyepoxy compound with an agent to make a cation as main components and a metal compound as a curing catalyst.
