ABSTRACT:
A silver halide color photographic material comprises a support, a blue sensitive layer, a green sensitive layer and a red sensitive layer and at least one non-light-sensitive layer. The non-light-sensitive layer is an intermediate layer arranged between the silver halide emulsion layers. According to the present invention, the non-light-sensitive intermediate layer contains a compound represented by the formula (1a) or (1b): ##STR1## in which R.sup.12 is an aliphatic group, an aromatic group or a heterocyclic group; M is --CO--, --SO.sub.2 --, --N(R.sup.15)CO--, --OCO-- or --N(R.sup.15)SO.sub.2 --; each of R.sup.14, R.sup.15 and R.sup.24 independently is hydrogen, an alkyl group or an aryl group; L is a divalent linking group necessary for forming a 5, 6 or 7-membered ring; each of R.sup.11, R.sup.13 and R.sup.21 independently is hydrogen or a substituent group of the hydroquinone nucleus; Time is a group which is released from the oxidation product of the hydroquinone nucleus to further release X; X is a development inhibitor; and t is 0 or 1. It is preferred that M is--SO.sub.2 --, --N(R.sup.15)CO--, --OCO-- or --N(R.sup.15)SO.sub.2 --.
