Abstract

1,057,952. Stabilizing dye images. EASTMAN KODAK CO. Oct. 16, 1963 [Oct. 18, 1962], No.42314/66. Divided out of 1, 57, 951. Heading G2C. Finished photographs containing dye images are stabilized by treatment with aqueous solutions of carbohydrazide or a salt thereof e. g. the hydrochloride or hydrobromide. The solution may contain buffering agents e. g. sodium citrate acetate or tetraphosphate.
