    Abstract: A process for producing an opaque coating on a substrate comprising: applying to said substrate a coating composition comprising an organic liquid comprising at least 85% by volume paraffinic hydrocarbons, a cellulose acetate propionate or cellulose acetate butyrate having an hydroxyl content of at least about 4%, a cross-linking agent compatible with the resin, a solvent for the resin and the cross-linking agent, and an acid catalyst for promoting cross linking of the resin with the crosslinking agent; and heating the composition to both cure the composition and to form voids which scatter light sufficiently to form an opaque coating.
