ABSTRACT:
A photographic element for a silver salt diffusion transfer process is described, comprising a silver halide light-sensitive element, an image receiving element and a processing element, the improvement wherein said photographic element contains a compound represented by formula (I) or (II) ##STR1## wherein the R.sub.O s, which may be identical or different from one another each represents hydrogen, a halogen atom, an alkyl group, a substituted alkyl group, a substituted or unsubstituted cycloalkyl group, an alkoxy group, a substituted alkoxy group, a substituted or unsubstituted alkylsulfonyl group, a substituted or unsubstituted arylsulfonyl group, a sulfamoyl group, an alkyl or arylsulfonamido group, a carbamoyl group, a carbonamido group, a heterocyclic group, a substituted or unsubstituted aryl group, an acyl group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted acyloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a primary amino group or a salt thereof, a secondary or tertiary amino group substituted by alkyl groups or aryl groups or the salt thereof, a nitro group, a hydroxyl group, a carboxyl group, a sulfonic acid group or a cyano group; R.sub.1 and R.sub.2 each represents hydrogen, an alkyl group, a substituted alkyl group or an aryl group; R.sub.3 and R.sub.4 each represents hydrogen, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group or a heterocyclic group; R.sub.3 and R.sub.4 may form a 5- or 6-membered ring together with the nitrogen atom, wherein the ring may further contain hetero atoms; R.sub.5 and R.sub.6 each represents hydrogen, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group or a heterocyclic group; A.sub.1 represents a divalent group; m represents an integer of 1 to 4; and n represents 1 or 2.
