Abstract
Abstract An active ethenic monomer having a functional epoxy group but free of functional hydroxy groups is copolymerized with another active ethenic monomer free of functional hydroxy groups in the presence of an alkylated amino resin dissolved in a nonaqueous medium. The polymerization can be carried out at the reflux temperature of the mixture and produces a stable dispersion of a polymeric material that is insoluble in the nonaqueous medium. Thermosetting films having an excellent combination of protective and decorative properties can be produced from the dispersions.
