Abstract: The present invention relates to a process for manufacturing a silver halide photographic element comprising the step of adding to a silver halide emulsion (1) an aryl compound having at least two hydroxyl groups and at least one additional substituent represented by a sulfonic group, an alkali metal sulfonate group, a hydroxyl group, a carboxy group or a hydroxymethyl group, and (2) a polyhydroxyalkyl derivative selected from the group consisting of non-hydrogenated polysaccharides having an average molecular weight higher than 10,000 and hydrogenated polysaccharides having an average molecular weight equal to or lower than 10,000. The use of such a combination to increase the speed to Dmin ratio of a silver halide photographic element and a silver halide element comprising such a combination is also claimed.
Abstract: Photographic elements are disclosed having on a support a silver halide emulsion layer sensitive to radiation other than blue light in addition to its intrinsic sensitivity to blue region, and a yellow filter layer between the silver halide emulsion layers and the source of exposure, the yellow filter layer containing a yellow filter dye represented by the structural formula: ##STR1## wherein: R is hydrogen, alkyl group or aryl group;R.sub.1 is aryl group or heterocyclic group;X is O or N--R.sub.2 where R.sub.2 is hydrogen or alkyl group;Y is N--R.sub.3 where R.sub.3 is hydrogen or alkyl group;n is 0 or 1;Z is hydrogen, alkyl group or aryl group;W is hydrogen, or W and Z, taken together, represent the atoms necessary to form an aryl group.
