    • An aqueous coating fluid is described comprising gelatin at a concentration of at least 1 wt % and a colloidal particle dispersed material phase at a volume fraction of at least 0.01, wherein at least 20% of the gelatin comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide. The present invention enables increasing the concentrations of a coating fluid containing gelatin and dispersed sub-micron colloidal materials, reducing the size of the sub-micron colloidal materials in such a coating fluid, and/or including higher molecular weight gelatin in such a coating fluid without detrimentally increasing the viscosity of such fluids. The invention further enables reducing the viscosity of an aqueous coating fluid containing gelatin and dispersed insoluble colloidal material, without needing to reduce the concentration of gelatin or colloidal materials, increase the size of the sub-micron colloidal materials, and/or reduce the molecular weight of the gelatin. Each such advantage may be achieved either individually, or in combinations to varying extents, without the need to fundamentally change the composition of the materials in the coating fluid.

    • An imaging element is described comprising one or more hydrophilic colloid layers which include gelatin as a film forming binder which has been chemically crosslinked with a gelatin hardener, wherein at least 20% of the gelatin of at least one of the one or more hydrophilic colloid layers comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide, and the gelatin is chemical crosslinked with a gelatin hardener at a level from 70 to 120 effective &mgr;mole hardener per gram of gelatin. Improvements are obtained in the wet mechanical strength of an imaging element comprising gelatin as a binder, without needing to increase the amount of chemical crosslinker with respect to the gelatin. The invention further enables the use of relatively low molecular weight gelatins without compromising the wet mechanical strength of imaging elements and without needing to increase the amount of crosslinker relative to the amount of gelatin. The invention also enables the selective improvement in the wet mechanical properties of layers with a high ratio of non-binder materials to binder without substantially increasing the amount of chemical crosslinker.

    • A process for making a direct dispersion of a photographically useful material is discloses comprising: mixing (i) an aqueous phase comprising a gelatin solution and (ii) a liquid organic phase comprising a photographically useful material under conditions of high shear or turbulence to form a fine dispersion of the organic phase having an average particle size of less than 0.5 micron dispersed in the aqueous phase; wherein the gelatin solution comprises a mixture of a first gelatin having an isoelectric point pH of less than or equal to 5.2 and a second gelatin having an isoelectric point pH of greater than or equal to 6.0. In accordance with the invention, the use of blends of a first gelatin having an pI of less than or equal to 5.2, such as a conventional lime processed gelatin, and a second gelatin having an pI of greater than or equal to 6.0, such as an acid processed gelatin, in a direct photographic dispersion yields a substantial reduction in viscosity in comparison to the use of the first gelatin alone, which reduction is greater than would be expected by just using blends of the first gelatin with another relatively low pI gelatin having an equivalent inherent viscosity as the second gelatin. In accordance with preferred embodiments of the invention, relatively low levels of APO gelatin may be used partially replacing LPO gelatin in a dispersion formulation to obtain significant viscosity reduction while minimizing adverse effects which may be associated with the use of higher levels of acid processed gelatin.

    • Silver halide light sensitive photographic elements are disclosed comprising a support bearing at least one yellow image forming hydrophilic colloid layer comprising a yellow dye-forming coupler and a trialkyl citrate coupler solvent of the formula C3H4(OH)(CO2R)3, where each R independently represents an alkyl group and the total number of carbon atoms for the three R groups combined is greater than 6. The combination of such citrate ester solvents with yellow dye forming couplers in photographic elements leads to both good reactivity and good image-dye light stability. The advantages of the invention are particularly useful for photographic color paper elements on reflective supports.
