Abstract
A method of producing a paint composition. The composition comprises a pigmented solution of a water-insoluble film-forming base resin in a water-immiscible liquid, the solution of the base resin being emulsifiable in an aqueous synthetic detergent solution. The method of making the paint composition includes the step of treating at least a portion of the pigment in dispersion in water-immiscible liquid with an auxiliary resin which (a) is co-emulsifiable in the aqueous detergent solution with the pigment when dissolved in the water-immiscible liquid of the paint composition and (b) is preferentially adsorbed by the pigment from a solution of both the base resin and the auxiliary resin in the water-immiscible liquid of the paint composition. The pigment of the paint composition comprises a pigment having an acidic surface. The final paint composition is satisfactorily emulsifiable in a 5% by weight solution of a synthetic detergent.
