Silver halide photographic photosensitive materials

Abstract

Disclosed is a silver halide photographic photosensitive material comprising a support having thereon a layer which contains at least one dye represented by general formula (I): ##STR1## wherein, R.sup.1 represents a hydrogen atom, a halogen atom, a sulfonic acid group, a carboxylic acid group or a CONHR, SO.sub.2 NHR, NHSO.sub.2 R, NHCOR or NHCONHR group (where R is an alkyl group, an aryl group or a heterocyclic group); R.sup.2 represents a group represented by SO.sub.2 R, COR or CONHR (where R has the same significance as before); R.sup.3 and R.sup.4 are the same or different, and each represents a hydrogen atom, an alkyl group, an alkoxy group, a hydroxy group, an amino group or a halogen atom; R.sup.5 and R.sup.6 are the same or different, and each represents an alkyl group, an aryl group, an acyl group or a sulfonyl group; R.sup.5 and R.sup.6 may be joined together to form a five or six membered ring; R.sup.5 and R.sup.6 may be joined with the adjacent R.sup.4 respectively to form five or six membered rings; n represents an integer of value 0 to 3; provided that there are at least three acidic substituent groups within the dye.
