| titleOfInvention |
Photographic elements containing cyan dye-forming coupler, coupler solvent and bisphenol derivative |
| abstract |
The invention provides a photographic element comprising a lightnsensitive silver halide emulsion layer containing a cyan dye-forming coupler ofnformula (I), a phenolic solvent of formula (II) and a bisphenol derivativencompound of formula (III):n nwherein:n R 1 represents an alkyl or aryl group; R 2 represents an alkyl or aryl group; and Z represents hydrogen or a group capable of being split off by oxidizedncolor developer; n nwherein:n each R independently represents a substituent group, and q represents anninteger from 1 to 3; and the total of the carbon atoms contained in all of the q R groups is at least 8nand not more than 15 carbon atoms; n nwherein:n R 3 represents an alkyl, aryl, alkoxy, aryloxy, or substituted amino group; L is a linking group having one atom between the phenyl rings; each R 5 independently represents an alkyl group; and each R 6 independently represents H or an alkyl group. |
