Method of stabilizing organic substrate materials to light

An element comprising an organic substrate material which is stabilized against the action of light and comprises the combination of at least one of a complex with at least one organic substrate material in an amount effective to stabilize the element to light, where said complex is represented by the formula (I):

• ##STR18## wherein M represents copper, cobalt, nickel, palladium or platinum, and R.sup.1 and R.sup.2 independently represent a hydrogen atom, an alkyl group, an aryl group, an acyl group, an N-alkylcarbamoyl group, an N-arylcarbamoyl group, or an N-alkylsulfamoyl group, an N-arylsulfamoyl group, an alkoxycarbonyl group or an aryloxycarbonyl group, said organic substrate material is a photographically useful dye having an absorption maximum in the range of from about 300 nm to 800 nm, and said complex not adversely affecting color hue or color purity of the photographically useful dye.

A color photographic material comprising at least one exposed and developed silver halide emulsion which contains a photographic dye image, wherein at least one layer containing a photographic dye image or an adjacent layer contains a complex of the formula (I) in an amount effective to stabilize the photographic dye image:

• ##STR19## wherein M represents copper, cobalt, nickel, palladium or platinum, and R.sup.1 and R.sup.2 independently represent a hydrogen atom, an alkyl group, an aryl group, an acyl group, an N-alkylcarbamoyl group, an N-arylcarbamoyl group, or an N-alkylsulfamoyl group, an N-arylsulfamoyl group, an alkoxycarbonyl group or an aryloxycarbonyl group.
