Abstract
A silver halide color photographic photosensitive material comprising a support having thereon a at least one silver halide emulsion layer, wherein at least one cyan dye forming coupler represented by the formula (I) indicated below ##STR1## wherein all the symbols are defined in the specification and at least one cyan dye forming coupler which can be represented by the formula (C) indicated below ##STR2## wherein all the symbols are defined in the specification are present in a layer on said support.
Claims18
The silver halide color photographic photosensitive material comprising a support having thereon at least one silver halide emulsion layer, wherein at least one cyan dye forming coupler represented by the formula (I) indicated below ##STR150## wherein R.sup.1 represents a substituted or unsubstituted alkyl group, alkenyl group, alkynyl group, cycloalkyl group or aryl group;
- X.sup.1 represents a single bond, --O--, --S--, --SO--, SO.sub.2, --COO--, ##STR151## wherein R.sup.6 represents a hydrogen atom, an acyl group having 1 to 36 carbon atoms or a group with the same meaning as R.sup.1 ;
- R.sup.7 is a hydrogen atom or a linear, branched chain or substituted alkyl group;
- R.sup.2 represents a group which can be substituted on a benzene ring;
- l represents an integer of 0 to 4;
- R.sup.3 represents a substituted or unsubstituted aryl group;
- and Z.sup.1 represents a hydrogen atom or a coupling-off group and at least one cyan dye forming coupler which can be represented by the formula (C) indicated below ##STR152## wherein R.sub.1 represents --CONR.sub.4 R.sub.5, --SO.sub.2 NR.sub.4 R.sub.5, --NHCOR.sub.4, --NHCOOR.sub.6, --NHSO.sub.2 R.sub.6, --NHCONR.sub.4 R.sub.5 or --NHSO.sub.2 NR.sub.4 R.sub.5 ;
- R.sub.2 represents a group which can be substituted on a naphthalene ring;
- l represents an integer of 0 to 3;
- R.sub.3 represents a substituent group;
- X.sub.1 represents a coupling-off group;
- R.sub.4 and R.sub.5, which may be the same or different, each represents a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group;
- and R.sub.6 represents an alkyl group, an aryl group or a heterocyclic group;
- and when l is 2 or 3, the R.sub.2 groups may be the same or different, or they may combine and form a ring;
- R.sub.2 and R.sub.3, or R.sub.3 and X.sub.1, may combine and form a ring;
- and dimers or larger oligomers formed by joining together via di- or higher valent groups at R.sub.1 R.sub.2, R.sub.3 or X.sub.1, are present in the same layer or in a different layer.
