The stability of titanium dioxide and copper phthalocyanine pigments dispersed in xylene/n -butanol solutions of alkyd/melamine resin has been studied in terms of zeta potential , sedimentation, resin adsorption and viscosity. The resins used were a coconut oil-modified alkyd resin and a butylated melamine resin. The pigments used were two rutile titanium dioxide pigments surface treated with alumina and alumina/silica, three phthalocyanine pigments of which crystalline modifications were a , β
