A method for stabilizing an organic substrate to light the substrate having an absorption maximum in the range of about 300 nm-about 800 nm, which comprises making at least one complex represented by following general formula (I) coexist with the substrate: ##STR1## wherein M represents an atom selected from the group consisting of Cu, Co, Ni, Pd and Pt, X represents O or S, R.sub.1 represents an alkyl group, an aryl group, an alkoxy group, an aryloxy group or, when taken together, the R.sub.1 's bound to the same phosphorus atom represent the non-metallic atoms necessary to complete a 6-membered ring together with the phosphorus atom. A photographic element containing the above complex is also claimed.
A method for stabilizing a photographically useful organic substrate selected from the group consisting of a quinoneimine dye, a methine or polymethine dye, an azo dye, an anthraquinone dye, an indoamine or indophenol dye, an indigoid dye, a carbonium dye, and a formazan dye to light said substrate having an absorption maximum in the range of about 300 nm-about 800 nm, which comprises making at least one complex in an amount sufficient to stabilize said color photographic material to light represented by following general formula (I) coexist with said substrate:
A color photographic material comprising at least one layer containing a photographic dye image wherein said layer or an adjacent layer contains a compound of the formula (I) in an amount sufficient to stabilize said color photographic dye image to light ##STR20## wherein M represents an atom selected from the group consisting of Cu, Co, Ni, Pd and Pt, X represents O or S, R.sub.1 represents an alkyl group, an aryl group, an alkoxy group, an aryloxy group or, when taken together, the R.sub.1 's bound to the same phosphorus atom represents the non-metallic atoms necessary to complete a 6-membered ring together with the phosphorus atom.
A diffusion transfer color photographic material comprising a photosensitive element and an image receiving element said image receiving element comprising a support having thereon a mordanting layer containing a complex of the formula (I) in an amount sufficient to stabilize said diffusion transfer color photographic material to light ##STR22## wherein M represents an atom selected from the group consisting of Cu, Co, Ni, Pd and Pt, X represents O or S, R.sub.1 represents an alkyl group, an aryl group, an alkoxy group, an aryloxy group or, when taken together, the R.sub.1 's bound to the same phosphorus atom represent the non-metallic atoms necessary to complete a 6-membered ring together with the phosphorus atom.
