Photographic element with yellow dye-forming coupler and stabilizing compounds |
| abstract |
In accordance with one embodiment of the invention, a photographic element is disclosed comprising a silver halide emulsion layer having associated therewith an acetanilide-based yellow dye forming coupler and a stabilizer compound of the formula S-I:wherein R0 represents an aryl or heterocyclic group; Ra is H or a substituent group; L represents an alkylene linking group and p represents 0 or 1; and Rb is a substituent group, provided that substituent groups represented by Ra and Rb may be joined to form a ring. The presence of substituted amine compounds of formula S-I improves the efficiency of dye formation reaction for acetanilide-based couplers. When used in combination with known bis-phenolic stabilizers, substantial improvements in the light stability of the image dyes can be also be obtained. Accordingly, photographic elements of the present invention upon exposure and photographic processing exhibit good activity and yield yellow dye images that have low fading when exposed to light. |
