Abstract
A novel cyan coupler for photographic dye, a process of forming a dye using the coupler and a photographic material containing the cyan coupler are disclosed. The coupler is represented by formula ##STR1## R, R.sub.1, X, m and n are defined in the specification.
Claims2
A color photographic material comprising a light sensitive layer containing silver salt and a coupler provided on a support wherein the coupler is represented by Formula I or II, ##STR10## wherein R represents a substituent, m is an integer from 1 to 5, n is an integer from 1 to 3, R's may be same or different when m or n is more than 2;
- R.sup.1 is an aliphatic group, an aryl group, heterocyclic group, an aliphatic oxy group, an aryloxy group, a heterocyclic oxy group, an acyloxy group, a carbamoyloxy group, a phosphonyloxy group, a carbamoyl group, a sulfamoyl group, an amino group, an acylamino group, an imido group, a sulfonamido group, a sulfamoyl group, an oxycarbonylamino group or a phosphnylamino group, each of which may have a substituent;
- X is a hydrogen atom or an atom or a group splitting off on the reaction with an oxidation product of a color developing agent.
