Abstract: A method for producing water-dispersible compositions is characterized in that an organo-synthetic resin having a softening point of not less than 65.degree. C. is uniformly heating-mixed with a surface active agent, the mixture obtained is then uniformly mixed with water with stirring while maintaining a temperature above the phase inversion temperature, and the resulting system comprising said resin, surface active agent and water is cooled below the phase inversion temperature to bring about phase inversion in the system, whereby said resin is dispersed in water in the form of fine particles (the phase inversion temperature shall be a temperature higher than 30.degree. C. below the softening point of the organo-synthetic resin but lower than the said softening point.

Abstract: This invention is directed to coating compositions for electrocoating electroconductive substrates for printed circuits comprising a pigment-containing finely divided synthetic resin powder in which the resin comprises an epoxy resin, and the pigment comprises pigments with 2-10 weight parts of finely divided silica, admixed with a water-dilutable cationic resin, and to methods of utilizing the composition for forming an insulating film on an electroconductive substrate.
