ABSTRACT:
Cyan-forming phenol type color couplers comprising in the 2-position of the phenol a benzamido group carrying on the benzene nucleus of the benzamido group at least one --Q--Rf group wherein Q is --O--, --S--, or --SO.sub.2 --, and Rf is a short-chain fluorine-containing group derived from hexafluoropropylene or trifluorochloroethylene.
These cyan-forming color couplers can be incorporated in (a) red-sensitized silver halide emulsion layer(s) of a photographic multilayer color element or in a non-light-sensitive colloid layer in water-permeable relationship with the red-sensitized emulsion layer(s).
