Abstract
A dye image stabilization process for color photographic sensitive elements which comprises processing a color photographic sensitive element containing at least one dye image stabilizer precursor with a solution containing divalent ions of at least one metal selected from Cu, Co, Ni, Pd and Pt is disclosed. Light fastness of dye images is thus improved.
