Abstract (en)
The reduction of cyan image dye to a leuco compound in a color photographic element by ferrous ion contained in a bleach processing solution is inhibited by the presence in the element of a polymeric latex having recurring units that are derived from certain lower alkoxyacrylate monomers optionally copolymerized with recurring units derived from certain acrylic ionomers.
