Cyan dye-forming couplers and photographic materials containing same |
摘要 |
Novel phenolic cyan dye-forming couplers contain a p-cyanophenylureido group in the 2-position and in the 5-position an acylamino group containing bulky alicyclic or heterocyclic substituents sufficient to provide steric interaction within the coupler molecule and the dye molecule derived therefrom. The couplers are useful in photographic emulsions.
