Abstract

An aqueous stable dispersion of positively charged polyfluorocarbon resin particles having a particle size of less than about 10 .mu.m contains both a cationic and a nonionic fluorocarbon surfactant in a molar ratio between 25:1 and 1:3.5 and in a total amount of at least 3.times.10.sup.-3 millimoles per m.sup.2 of surface area of said particles. The fluorocarbon surfactants give the dispersions storage-stability even in the presence of a strong electrolyte and make them suitable for use in electroplating baths.
