| titleOfInvention | Use of substituted phenols to improve the light fastness of magenta images |
| abstract | The combination of a magenta dye image-forming coupler, such as a phenylpyrazolone, with a substituted phenol in a photographic material provides an enhancement in the light stability of the resultant magenta image dye. The phenol has formula (I), wherein each R is the same or different and is an unsubstituted or substituted alkyl, halogen, cyano, SO2R<1>, SO2NHR<1>, NHSO2R<1> or COOR<1> group, in which R<1> is an unsubstituted or substituted alkyl or aryl group and n is from 1 to 5. The phenol may totally or partially replace the conventional coupler solvent. The combination is useful in single colour or multi-colour photographic silver halide emulsion materials and processes. |
