Claims19
A silver halide color photographic material comprising a support having thereon at least one layer containing at least one compound represented by the following formula (I), (II) or (III):
- ##STR46## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.11 and R.sub.12 may be the same or different and each represents a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group;
- Y represents a group of the following formula:
- ##STR47## R.sub.a, R.sub.b, R.sub.7, R.sub.8, R.sub.9, R.sub.10, R.sub.13, R.sub.14, R.sub.15, R.sub.16, R.sub.17 and R.sub.18 may be the same or different and each represents a hydrogen atom or a substituent group, or R.sub.a and R.sub.b may be combined together to form a five-membered to seven-membered ring;
- R.sub.c represents an acyl group;
- R.sub.19 represents a substituent group;
- Z represents --S--, --SO--, --SO.sub.2 --, --O-- or --N(R.sub.20)--;
- R.sub.20 has the same meaning as R.sub.13 ;
- n represents 0 or an integer of 1 to 2;
- and m represents 0 or an integer of 1 to 5 and when m is 2 to 5, two or more R.sub.19 groups may be the same or different, wherein said compound of formula (I) is a compound represented by the following formula (I-a):
- ##STR48## wherein n and Y are as defined in general formula (I);
- R.sub.21 and R.sub.22 may be the same or different and each represents a substituent group;
- k and k' each represents 0 or an integer of 1 to 5;
- when k and k' are each 2 or greater, two or more R.sub.21 and R.sub.22 groups may be the same or different, and the R.sub.21 or R.sub.22 groups at the ortho-position relative to each other may be combined together to form a five-membered to seven-membered ring, and wherein said compound of formula (II) is a compound represented by the following formula (II-a):
- ##STR49## wherein R.sub.7, R.sub.8, R.sub.9, R.sub.10 and n are the same as defined in general formula (II);
- R.sub.23 and R.sub.24 may be the same or different and each represents a substituent group;
- and p and p' each represents 0 or an integer of 1 to 5;
- when p and p' are each 2 or greater, two or more R.sub.23 and R.sub.24 groups may be the same or different, and the R.sub.23 and R.sub.24 groups at the ortho-position relative to each other may be combined together to a form five-membered to seven-membered ring.
