Process for preparing an aqueous paint composition by:- (a) mixing a pigment powder having a particle size less than 20 micrometres, a cross-linking agent and an epoxy resin to form a liquid, solvent-free paste, (b) reacting the resultant paste with a secondary amine, and optionally also a primary amine, to provide for at least one N-H function per epoxy group of the epoxy resin, at a temperature in the range 20 DEG C to 140 DEG C, and (c) neutralising the resulting suspension of particles coated with epoxy-amine adduct and cross-linking agent. p
