PURPOSE: The titled aqueous dispersion excellent in storage stability and useful for paints, obtained by emulsion-polymerizing a specified alkyl (meth)acrylate with OH group-and/or epoxy group-containing unsaturated monomers and benzoguanamine resin. n CONSTITUTION: To an aqueous medium containing an emulsifier (e.g., sodium laurylsulfate) and a polymerization initiator (e.g., ammonium persulfate) is added a monomer mixture consisting of 50W97wt% alkyl methacrylate wherein the alkyl is of 1W4 C (e.g., methyl acrylate), 2W30wt% OH group- and/or epoxy group-containing unsaturated monomers (e.g., 2-hydroxyethyl acrylate), 0W20wt% unsaturated monomer copolymerizable therewith (e.g., styrene) and 1W30wt% benzoguanamine resin (e.g., dehydrated benzoguanamine). The resulting mixture is emulsion-polymerized at 0W90°C to obtain a thermosetting aqueous dispersion. n COPYRIGHT: (C)1984,JPO&Japio |
