ABSTRACT:
Silver halide photographic material which has a hydrophilic colloid layer containing a solid micrograin dispersion of compounds represented by the following general formula (I): ##STR1## wherein, T.sup.0, T.sup.1 and T.sup.2 each independently represents a hydrogen atom, a halogen atom or a cyano, nitro, carboxy, alkyl, aryl, alkoxy, aryloxy, alkylthio, arylthio, alkylsulfonyl, arylsulfonyl, sulfamoyl, carbamoyl, amino, sulfonamido, carbonamido, ureido, sulfamoylamino, hydroxyl, alkenyl or acyl group, R.sup.3 and R.sup.4 each independently represents a hydrogen atom, a halogen atom or an alkoxy, alkyl, alkenyl, aryloxy or aryl group, R.sup.5 and R.sup.6 each independently represents a hydrogen atom or a group in which hydrogen atom substitution is possible, and R.sup.7 and R.sup.8 each independently represents an alkyl, aryl, vinyl, acyl or alkyl- or arylsulfonyl group, provided that rings may be formed by linkage of T.sup.1 with T.sup.2, R.sup.3 with R.sup.5, R.sup.4 with R.sup.6, R.sup.7 with R.sup.8, R.sup.5 with R.sup.7 and R.sup.6 with R.sup.8. The compound of formula (I) is designed to dye specific hydrophilic colloid layers in the photographic material and to decolor rapidly during development processing.
