发明名称 PROCESS FOR FORMING ANTI-HALATION LAYERS ON POLYESTER PHOTOGRAPHIC FILM SUPPORTS
摘要 <p>A process for forming an anti-halation layer on the surface of a polyester photographic film support comprises the steps of (1) subjecting the surface to an activation treatment such as, for example, corona discharge treatment; (2) coating the activated surface with a composition comprising an anti-halation agent, such as carbon black, and an alkali-soluble polymeric binder, such as cellulose acetate hexahydrophthalate, dispersed in a liquid organic medium; and (3) drying the coating to thereby form an anti-halation layer which is strongly adherent to the polyester film support yet is readily removable by an alkaline photographic processing solution.</p>
