Photographic element containing a reductone and, in the most blue light sensitive layer, a fine grain emulsion

The invention provides a multicolor photographic element comprising a support bearing at least two silver halide emulsion layers having different sensitivities to blue light, a silver halide emulsion layer sensitive to green light, and a silver halide emulsion layer sensitive to red light, wherein: (1) the element comprises a compound of formula (I): wherein R1 and R2 independently represent H, an alkyl group or an aryl group, provided that R1 and R2 may be joined to form a ring; R3 is selected from the group consisting of H, alkyl, aryl, and acyl groups; R4 and R5 are independently selected from the group consisting of H, OH, alkyl, and aryl groups; n is 1 or 2; and (2) the silver halide emulsion layer of the element that is most sensitive to blue light contains a silver halide grain population such that from 3 to 20 wt% of the total silver halide grains in the emulsion layer have a size (equivalent circular diameter) less than 0.2 micrometers. The element exhibits an improved combination of blue speed, raw stock keeping, and latent image keeping.
