ABSTRACT:
A photographic element and an aqueous coating composition for providing a layer to a photographic element are disclosed. The coating composition comprises gelatin in a concentration greater than about 6% by weight, and a palladium complex having the structure: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, and R.sup.8 are independently selected from hydrogen, alkyl, alkenyl, aryl or alkaryl, the alkyl, alkenyl, aryl, or alkaryl optionally being substituted with a hydroxy, sulfonate, amino or ammonium group; and wherein any two of R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, and R.sup.8 can be bonded to form a ring;
Z.sup.1 and Z.sup.2 independently represent the number of carbon atoms necessary to form a 5 or 6 membered ring, inclusive of palladium, wherein the carbon atoms may be substituted with hydrogen, sulfonate, alkyl, alkenyl, aryl or alkaryl, the alkyl, alkenyl, aryl, or alkaryl optionally being substituted with a hydroxy, halogen, sulfonate, amino or ammonium group; and
n is -2 to 4.
