摘要： A process for making a direct dispersion of a photographically useful material comprising: mixing (i) an aqueous phase and (ii) a liquid organic phase under conditions of shear or turbulence to form a dispersion of the organic phase dispersed in the aqueous phase; wherein the liquid organic phase comprises one or more photographically useful materials and one or more organic solvents having a boiling point of at least 150° C., a molecular weight less than or equal to 300, and a solvatochromic parameter β value greater than or equal to 0.50, wherein the weight ratio of the sum of the solvents having a boiling point of at least 150° C., a molecular weight less than or equal to 300, and a solvatochromic parameter β value greater than or equal to 0.50 to the photographically useful materials does not exceed 0.25. The use of relatively low levels of specified high-boiling organic solvents enables the direct dispersion of hydrophobic photographically useful materials with low solubility in conventional primary photographic useful solvents without crystallization problems or excessive decomposition.

摘要： The invention provides a color negative photographic element comprising a light sensitive silver halide emulsion imaging layer having associated therewith a cyan dye-forming coupler dispersion comprising a first 2-ureido-5-acylamino substituted phenolic cyan dye-forming coupler [P], a second phenolic cyan dye-forming coupler [AP] where the 2-substituent is other than an ureido group, a substantially non-color-developable phenolic activator compound [ACT], and a non-phenolic organic coupler solvent having a boiling point of at least 150C; wherein compounds represented by [P], [AP], and [ACT] are present in the coupler dispersion in relative weight fractions of from 0.30 to 0.65 for [P], from 0.15 to 0.35 for [AP], and from 0.15 to 0.35 for [ACT], provided the sum of the relative weight fractions for [P]+[AP]+[ACT]=1, and the weight ratio of the non-phenolic coupler solvent in the coupler dispersion is from 0.30 to 2.0 relative to the sum of [P]+[AP]+[ACT]. Photographic elements incorporating the dispersion formulation of this invention provide good activity, a cyan dye of high density and acceptable absorption maximum for color negative films. In addition, partial substitution of less expensive cyan auxiliary phenolic coupler [AP] and activator [ACT] for cyan phenolic coupler [P] advantageously allows cost savings.

摘要： A multi-color photographic silver halide element has a total gelatin level on the imaging side of the support is less than 9000 mg/m2, and bulk gelatin-to-junk weight ratio for all of the light sensitive layers on the imaging side of the support is greater than 1.5. This weight ratio is defined by: Bulk gelatin-to-junk ratio=[(Bgel×Bgel/junk)+(Rgel×Rgel/junk)+(Ggel+Ggel/junk)]÷(Bgel+Rgel+Ggel) wherein Bgel is the total gelatin level for blue light sensitive layers, Bgel/junk is the gelatin-to-junk ratio for blue light sensitive layers, Rgel is the total gelatin level for red light sensitive layers, Rgel/junk is the gelatin-to-junk ratio for red light sensitive layers, Ggel is the total gelatin level for green light sensitive layers, and Ggel/junk is the gelatin-to-junk ratio for green light sensitive layers. The imaging layers can be thinned without undesirable loss in sensitometric properties and in increase in dust and dirt generation while providing reduced material costs and improving development properties.

摘要： A color photographic element has a reflective support and a blue light sensitive color record, a green light sensitive color record, and a red light sensitive color record can be used to provide color photographic prints. The element also has a non-light sensitive interlayer between the green light and red light sensitive color records. This interlayer comprises a hydrophilic colloid and an acrylic latex polymer having a glass transition temperature (Tg) of less than 0° C. The presence of this acrylic latex polymer in the interlayer reduces the formation of a cyan line defect when the color photographic print is folded or creased, such as in photobooks.
