A photographic element is detailed which provides for improved resolution by decreasing the blue and ultraviolet radiation typically associated with internal scatter and print-through. These and other improvements are provided in a photographic element comprising a support having thereon at least one hydrophilic colloid layer, wherein at least one said hydrophilic colloid layer comprises a radiation sensitive silver halide emulsion layer, at least one said hydrophilic colloid layer comprises a filter dye consisting essentially of a compound with generic formula: ##STR1## wherein: A represents a counterion chosen from the set consisting of lithium, sodium, potassium, ammonium and alkylammonium of 1 to 15 carbons; Z represents the atoms chosen from the group consisting of carbon, sulfur, nitrogen, oxygen and selenium necessary to form an optionally substituted ring.
A photographic element comprising at least one hydrophilic colloid layer wherein said hydrophilic colloid layer comprises a dye of the formula:
