摘要:
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.
