A photographic element is described comprising a support bearing at least one blue light sensitive silver halide emulsion layer and an ultraviolet filter layer above the light sensitive layer, wherein the ultraviolet filter layer comprises an ultraviolet absorbing dibenzoylmethane compound of formula (I) where R1 through R5 are each independently hydrogen, halogen, nitro, or hydroyxl, or further substituted or unsubstituted alkyl, alkenyl, aryl, alkoxy, acyloxy, ester, carboxyl, alkyl thio, aryl thio, alkyl amine, aryl amine, alkyl nitrile, aryl nitrile, arylsulfonyl, or 5–6 member heterocycle ring groups. The present invention describes photographic elements that include materials that deliver a preferred UV absorption spectrum that provides adequate spark protection, and minimizes UV radiation incident on the element during camera exposure so that accurate color rendition can be achieved, while maximizing photographic speed in the blue record.
