This invention relates to a 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 of the dye image forming units contains layers of differing sensitivities, and the layer of highest sensitivity contains a development promoting agent or a specific coupler as described herein, or a combination thereof, and a silver halide emulsion comprising tabular silver halide grains having associated therewith at least two dye layers comprising (a) an inner dye layer adjacent to the silver halide grain and comprising at least one dye, Dye 1, that is capable of spectrally sensitizing silver halide and (b) an outer dye layer adjacent to the inner dye layer and comprising at least one dye, Dye 2, wherein the dye layers are held together by more than one non-covalent force; the outer dye layer absorbs light at equal or higher energy than the inner dye layer; and the energy emission wavelength of the outer dye layer overlaps with the energy absorption wavelength of the inner dye layer.

Bleach compositions and methods that are improvements over those provided by Fyson, U. S. Pat. No. 4,294,914, are disclosed. A highly preferred bleach composition of this invention (a) has the ferric complex of methyliminodiacetic acid as a bleaching agent, and additionally comprises (b) at least 0. 9 mole of acetic acid per liter, (c) from about 15 to about 35 grams per liter of potassium bromide; and (d) has a pH of from about 2. 5 to about 4. This invention includes the discovery of a synergistic bleaching coaction of a bleach (i) comprising an alkyliminodiacetic acid such as methyliminodiacetic acid, and (ii) which has a pH of from about 3. 5 to about 4. 5 , and (iii) in which the amount of ferric iron is from about 2 to about 16 grams per liter. This coaction between iron levels and pH was previously unknown and was unexpected. Bleach formulations of this invention can be used in the processing of color photographic materials, such as film.

Color silver halide photographic elements having a yellow dye image-forming unit comprises at least one blue-sensitive silver iodobromide emulsion layer that has silver iodobromide grains. The silver iodobromide grains have initially associated therewith at least two blue spectral sensitizing dye layers comprising: (a) an inner dye layer adjacent the silver iodobromide grains comprising at least one anionic blue spectral sensitizing Dye 1, and (b) an outer dye layer adjacent to the inner dye layer comprising at least one cationic blue spectral sensitizing Dye 2. Dye 2 absorbs light at equal or higher energy than Dye 1. The maximum energy emission wavelength of Dye 2 overlaps but is not exactly corresponding to the maximum energy absorption wavelength of Dye 1. The silver iodobromide grains also have initially associated therewith an amine borane compound and a thiosulfonate compound.

In a system having a fluid filter that is automatically backwashed each time the differential pressure thereacross reaches a predetermined value, the desired base rate at which the drop across the filter should increase during its initial filtering sequence (i. e. , before backwash) is determined and stored in digital format in a process controller along with a preset maximum differential pressure at which backwash is set to occur. During use of the filter the actual rate of change of the pressure drop thereacross is monitored continuously and compared with the rate that is stored in the controller. Whenever the actual rate of change of the pressure drop across the filter differs from the base rate, which is the usual case, the present backwashing pressure is automatically adjusted--usually downwardly. This reduction continues until the actual drop across the filter finally reaches the adjusted value of the preset backwashing pressure, at which time backwashing of the filter is automatically commenced. In a preferred embodiment, the adjustment is based upon the time differential at a given instant between the actual filter time and the desired or base curve time, and the difference is used to reduce the preset pressure in accordance with the inverse of the base curve rate.

Cyan dye density can be maximized in color developed silver halide photographic color materials and bleaching accelerated by contacting the materials with a bleaching or bleach-fixing composition comprising a mixture of a ferric complex of an aminopolycarboxylic acid as a bleaching agent, and an aromatic pyridinyl mono- or dicarboxylic acid in uncomplexed form. The molar ratio of the uncomplexed aromatic carboxylic acid to the ferric ion in the bleaching composition is from about 0. 02:1 to about 0. 8:1.
