ABSTRACT Aqueous dispersions of film-forming polymer particles are prepared by first forming a cationically or anionically stabilised dispersion in water of a solution of preformed polymer or polymer plasticiser in initial polymerisable monomer; then polymerising the monomer and forming disperse polymer particles; and thereafter adding further polymerisable monomer which is then polymerised. The Tg of polymer prepared from the further monomer is higher than that of polymer prepared from the initial monomer. The polymer dispersions are useful in providing thick electrodeposited coatings.
