Abstract
Abstract A RESIN SUCH AS A VINYL CHLORIDE COPOLYMER IS DISSOLVED IN AN OXYGEN-CONTAINING SOLVENT, SUCH AS METHYL ETHYL KETONE, AND AN ALUMINUM PIGMENT PASTE IS DISPERSED THEREIN. THE PROPORTION OF HYDROCABON SOLVENT IS INCREASED UNTIL THE RESIN PRECIPITATES COLLOIDALLY ON THE ALUMINUM PIGMENT TO FORM A CONCENTRATE IN WHICH THE ALUMINUM PARTICLES ARE PROTECTED. THE CONCENTRATE CAN BE INCORPORATED IN PAINTS WHICH ARE ELECTROSTATICALLY SPRAYABLE.
