Abstract: A photographic element comprises a light-sensitive silver halide emulsion layer having associated therewith (a) a 1H-pyrazolo[1,5-b][1,2,4]triazole dye-forming coupler; (b) a sulfonamide compound free of aromatic substituents directly linked to the sulfonamide nitrogen or sulfur atoms and (c) a dialkoxy substituted aromatic compound.

Abstract: Photographic elements are disclosed comprising a silver halide emulsion layer having associated therewith a dye forming coupler and a compound of the following Formula I: R1R2N—C(O)—(R)p—C(O)—NR3R4 wherein R represents a hydrocarbon linking group; p=0 or 1; and each of R1, R2, R3 and R4 independently represents an aromatic, cyclic, linear or branched chain hydrocarbon group, or R1 and R2 or R3 and R4 combine together to form a ring with the associated nitrogen atom to which they are attached; with the proviso (i) at least one of R1, R2, R3 and R4 comprises an aromatic, cyclic, secondary alkyl, or otherwise or branched hydrocarbon group, or (ii) at least R1 and R2 or R3 and R4 combine together to form a ring with the associated nitrogen atom. Photographic elements of the present invention upon exposure and photographic processing exhibit good activity and yield dye images that have unexpected and substantial improvements in the stability of the formed image dyes.

Abstract: Disclosed is a photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith (a) a pyrazolotriazole dye-forming coupler; (b) a cyclic aminosulfone first stabilizer; and (c) a sulfonamide compound co-stabilizer free of aromatic substituents and having a melting point of less than 150° C. The image dye formed by the coupler exhibits improved dye light stability.

Abstract: Photographic elements are disclosed comprising a silver halide emulsion layer having associated therewith a magenta coupler and a magenta dye stabilizer compound of the formula S-I: ##STR1## wherein R.sup.0 represents an aryl group or a heterocyclic group; L.sub.1 and L.sub.2 are independently linear alkylene or cycloalkylene linking groups; and R.sup.a and R.sup.b are independently selected substituent groups at least one of which has a .sigma.* value of at least 1.8. Compounds in accordance with formula S-I act as singlet oxygen quenchers and are effective stabilizers for magenta dye images. Photographic elements of the present invention upon exposure and photographic processing yield magenta dye images that have low fading when exposed to light.
