Cyan dye-forming coupler and photographic element containing same.

摘要

A novel phenolic cyan dye-forming coupler contains a p-cyanophenylureido group in the 2-position and in the 5-position an acylamino substituent containing a sulfone group having 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.
