Abstract (en)
[origin: EP0271323A2] A novel phenolic cyan dye-forming coupler contains a p-cyanophenylureido group in the 2-position and in the 5-position an acylamino group containing bulky substituents sufficient to provide steric interaction within the coupler molecule and the dye molecule derived therefrom. The coupler is useful in a photographic emulsion.
