摘要： The invention relates to a novel kind of anthranilic acid compound that releases a UG as a function of chemical bond cleavage according to Formula (I): Q-(AAS)-UG where UG is an useful group and is chemically bonded to (AAS); (AAS) is an anthranilic acid switching group; and Q is a group in which the bond to (AAS) is broken so that the -(AAS)-UG fragment subsequently decomposes to the free UG. In one embodiment this invention relates to a multilayer silver halide photographic element comprising a support bearing a cyan dye image-forming unit comprised of at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, and a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler, wherein at least one layer additionally contains an anthranilic acid compound according to Formula (II): G-(TG1)q-(AATG)-(TG2)p-PUG where G is a group in which the bond to the timing group is cleaved upon reaction with oxidized developer; TG1 and TG2 represent any known timing or switching group and may be the same or different; q and p are independently 0 or 1; AATG represents an anthranilic acid timing group and PUG is a photographically useful group.

摘要： The invention provides a color photographic element comprising at least one light-sensitive silver halide emulsion layer or a non silver-containing light-insensitive layer, in which at least one of these layers contains a colorless heterocyclic compound having either one or two hetero atoms in the ring or ring system, being other than an imidazole compound, that undergoes less than 10% chemical or redox reaction directly with oxidized developer and which has a partition coefficient to enable the photographic speed of the element to be increased by at least 0.03 stop without increasing granularity, compared to the same element without the compound. The heterocyclic compounds increase speed without a concomitant increase in size of the light-sensitive silver halide grains.

摘要： This invention relates to a multilayer silver halide photographic element, generally processed with phenylenediamine based developer solutions, comprising a support bearing a cyan dye image-forming unit comprised of at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, and a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler, wherein at least one layer additionally contains a 2-substituted-5-amino-1-napthol DIR according to Formula (I): wherein: X is chosen from among hydrogen, halogen atoms, an alkyl group with 6 carbon atoms or less or a N-substituted carbamoyl group where the N substituent is either an alkyl group with 6 carbon atoms or less or an aryl group with 8 total carbon atoms or less; R is a carbonyl or sulfonyl group; and INH is an inhibitor of silver development. It has been found that such 2-substituted-5-amino-1-napthol based DIRs have improved properties and can provide a conventional silver halide photographic element with excellent image structure and color reproduction.

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： A photographic element including a support and first and second green-sensitive silver halide emulsion layers of different sensitivity, wherein the layer of higher sensitivity includes a two-equivalent magenta dye-forming coupler selected from the group consisting of a pyrazolone coupler having a structure according to formula I and a pyrazoloazole coupler having a structure according to formula II as set forth in the disclosure, and the layer of lower sensitivity includes a two-equivalent magenta dye-forming coupler selected from the group consisting of couplers defined by formulas I and II. The activity of the magenta dye-forming coupler present in the layer of lower sensitivity is less than the activity of the coupler present in the layer of higher sensitivity.
