Abstract
The present invention relates to photographic photosensitive material comprising a support having thereon at least one silver halide emulsion layer. The photosensitive material contains at least one cyan dye forming coupler represented by formula (I) ##STR1## and at least one cyan dye forming coupler represented by formula (II) ##STR2## in proportions, respectively from 20 to 99 wt % and from 1 to 80 wt %, wherein all the symbols are defined in the specification.
Claims18
A photographic photosensitive material comprising a support having thereon at least one silver halide emulsion layer, said photosensitive material containing at least one cyan dye forming coupler represented by formula (I):
- ##STR117## and at least one cyan dye forming coupler represented by formula (II):
- ##STR118## in proportions, respectively, from 20 to 99 wt % and from 1 to 80 wt %, based on the total amount of both couplers of formulae (I) and (II), 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--, ##STR119## R.sup.2 represent a group which can be substituted on a benzene ring;
- l represents an integer from 0 to 4;
- R3 is selected from the group consisting of 4-cyanophenyl, 4-cyano-3-halogenophenyl, 3-cyano-4-halogenophenyl, 4-alkylsulfonylphenyl, 4-alkylsulfonyl-3-halogenophenyl, 4-alkylsulfonyl-3-alkoxyphenyl, 3-alkoxy-4-alkylsulfonyl-phenyl, 3,4-dihalogenophenyl, 4-halogenophenyl, 3,4,5-trihalogenophenyl, 3,4-dicyanophenyl, 3-cyano-4,5-dihalogenophenyl, 4-trifluoromethylphenyl and 3-sulfonamidophenyl;
- R.sup.4 and R.sup.5 each independently represent a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, an acyl group, an alkoxycarbonyl group or an aryl group;
- Z.sup.1 represents a hydrogen atom or a coupling-off group;
- R.sup.6 represents a hydrogen atom, an acyl group or a group as defined for R.sup.1 ;
- and R.sup.7 represents a hydrogen atom or a group as defined for R.sup.1.
