Disclosed is a photographic element comprising a support bearing a blue light sensitive record containing at least three layers having different levels of light sensitivity arranged in the order slowest to fastest with the slowest layer closest to the support and the fastest layer closest to the light exposure source, wherein (a) all of the blue-sensitive layers are closer to the light exposure source than the layers sensitive to any other color; (b) the slowest blue light sensitive layer is at least 1.0 log E slower than the next fastest blue light sensitive layer when measured at a density of 0.15 above Dmin, and contains a particular type of cyan dye-forming development inhibitor releasing (DIR) coupler; and (c) all of the blue light sensitive layers other than the slowest blue light sensitive layer independently contain a certain type of yellow dye-forming DIR coupler. Embodiments of the invention provide improved color rendition without sacrificing blue density.

Color negative element containing triple-coated blue record and method of imaging using same

The invention relates to a silver halide photographic emulsion comprising silver halide grains and the reductone of Formula I ##STR1## wherein R.sub.1 and R.sub.2 are the same or different, and may represent H, alkyl, cycloalkyl, aryl, or an alkyl group with a solubilizing group such as --OH, sulfonamide, sulfamoyl, or carbamoyl, R.sub.1 and R.sub.2 may be joined to complete a heterocyclic ring such as aziridinyl, azetidinyl, pyrrolidinyl, piperidinyl, morpholinyl, piperazinyl, or pyridinyl, R.sub.4 and R.sub.5 are H, OH, alkyl, aryl, cycloalkyl, or may together represent an alkylidene group, n is 1 or 2 and R.sub.3 is H, alkyl, aryl, or CO.sub.2 R.sub.6 where R.sub.6 is alkyl, and wherein the logarithm of the partition coefficient for the reductone when equilibrated as a solute between n-octanol and water (logP) is less than 0.293.

Undesirable particle growth of particles comprising a hydrazide oxidized developer in a photographic dispersion can be significantly reduced when the hydrazide scavenger is in the form of a dispersion of crystalline solid particles dispersed in an aqueous medium. The dispersion is prepared by milling crystalline solid particles of the scavenger in an aqueous medium in the presence of a dispersing agent and in the substantial absence of an organic solvent.
