Photographic element with yellow dye-forming coupler and stabilizing compound

摘要

A photographic element is disclosed comprising a silver halide emulsion layer having associated therewith an acetanilide based yellow dye forming coupler and a compound of the following Formula I: wherein R<1>, R<2> and R<3> are each independently aromatic, cyclic, linear, or branched chained hydrocarbon groups. The invention provides photographic elements which exhibit exceptional yellow dye light stability, and which retain desirable properties derived from the use of acetanilide based yellow dye-forming couplers, particularly when used in combination with substituted phenolic and/or thiomorpholine dioxide stabilizers. In addition to stabilizing properties, compounds of Formula I have organic solvent properties, and accordingly may be advantageously used partly or totally in place of conventional high boiling permanent and/or auxiliary organic coupler solvents to disperse the acetanilide-based couplers.
