摘要： Color reversal photographic elements can be effectively processed to provide positive color images using bleaching compositions in which the primary bleaching agent is a ferric complex of 1,3-propylenediaminetetraacetic acid or a salt thereof. Any potential precipitation of the bleaching agent is inhibited by the presence of at least 0.005 mol/l of an organic polyphosphonic acid, an aminopolysuccinic acid, or a polycarboxylic acid containing at least one hydroxy group as a compound. This compound can be added directly to the bleaching composition or introduced from carryover from a previous photoprocessing step, such as a prebleaching step using color reversal processing.

摘要： Specific aromatic compounds having an extended planar &pgr; system are useful as spectral sensitizing dye stain reducing agents in photographic processing compositions and methods for providing color or black-and-white images in various photographic silver halide materials. These compounds are devoid of diaminostilbene fragments or fused triazole nuclei. They are particularly useful in fixing and bleaching compositions in the processing of color photographic silver halide materials, but can also be used in various other processing compositions.

摘要： A process for controlling the silver halide grain-to-grain distribution of a variable contrast dye in a light sensitive silver halide emulsion layer of a variable contrast photographic element, and thereby adjusting the low contrast characteristic curve of the element, is disclosed comprising the process steps of adding a green variable contrast sensitizing dye of the following formula (I) to a silver halide emulsion for a variable contrast photographic element, adding a blue sensitizing dye of the following formula (II) to the same silver halide emulsion, and coating the emulsion on a support. In the process, the green and blue sensitizing dyes are added to the emulsion at substantially the same time, and the green dye is added in an amount less than that required to impart maximum sensitivity to all of the silver halide in the emulsion. ##STR1## In formula (I), R.sup.1, R.sup.2, R.sup.6 and R.sup.7 each independently represent hydrogen, halogen, hydroxy, or substituted or unsubstituted alkyl, alkenyl, alkoxy, alkylamino, alkylthio, aryl, aryloxy, arylamino or arylthio. R.sup.3, R.sup.4 and R.sup.5 each independently represent substituted or unsubstituted alkyl or aryl. X represents a counterion as needed to balance the charge of the molecule. In formula (II), Z represents the atoms necessary to complete an optionally further substituted five- or six-membered heterocyclic ring, R.sup.8 represents substituted or unsubstituted alkyl or aryl, and R.sup.9 represents hydrogen, substituted or unsubstituted alkyl or aryl, or a heterocycle.

摘要： Color photographic elements can be effectively processed to provide color images using biodegradable bleaching compositions in which the bleaching agent includes a pyridinecarboxylic acid or 2,6-pyridinedicarboxylic acid chelating ligand. The bleaching composition is stabilized by incorporation of an organic amine base instead of the conventional inorganic base.

摘要： A photographic prebleaching or conditioning composition is useful for providing color positive images in color reversal photographic materials. This composition includes at least 0.0001 mol/l of a cyclic mercapto bleach accelerating agent and at least 0.0001 mol/l of a water-soluble or water-dispersible 2,6-diarylaminotriazine or diaminostilbene dye stain reducing agent. The amounts of the dye stain reducing agent and bleach accelerating agents are determined according to the following equation: [bleach accelerating agent, mol/l]≧0.01−10[dye stain reducing agent, mol/l].
