A silver halide color photographic material having low color stain and color fog, which contains at least one substantially colorless compound selected from the group consisting of compounds represented by formula (I) ##STR1## and alkaline unstable precursors thereof, bis, tris and tetrakis compounds derived from the compound, and polymers derived from the compound; wherein R.sup.1 and R.sup.2 each represents a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl, acylamino, alkoxy, aryloxy, alkylthio, arylthio, sulfonyl, carbamoyl, or sulfamoyl group; or R.sup.1 and R.sup.2 together form a carbocyclic ring; R.sup.3 represents a hydrogen atom or an alkyl group; and R.sup.4, R.sup.5, R.sup.6, R.sup.7, and R.sup.8 each represents a hydrogen atom, a halogen atom, a hydroxyl group, a cyano group, a nitro group, or a substituted or unsubstituted alkyl, acylamino, sulfonamido, alkoxy, aryloxy, alkylthio, arylthio, amino, acyl, acyloxy, carbamoyl, carbamoylamino, carbamoyloxy, sulfamoyl, sulfamoylamino, alkoxycarbonyl, aryloxycarbonyl, alkoxycarbonylamino, aryloxycarbonylamino, akloxycarbonyloxy, aryloxycarbonyloxy, heterocyclic ring, alkoxysulfonyl or aryloxysulfonyl group; or two adjacent groups together form a carbocyclic ring or a heterocyclic ring; the sum of the carbon atom number of R.sup.1 to R.sup.8 is at least 8; and the compound of formula (I) is substantially insoluble in water and does not form a color image by coupling reaction with an oxidized product of a developing agent.
A silver halide color photographic material containing at least one substantially colorless compound selected from the group consisting of compounds represented by formula (I) ##STR10## and alkaline unstable precursors thereof, bis, tris and tetrakis compounds derived from the compound, and polymers derived from the compound;
