ABSTRACT:
A method of processing a photographic material having, in the backing layer, at least one mercapto pyrimidine compound of formula (I), with an automatic developing machine, where the amount of the replenisher of the developer per unit area of the material being processed is reduced. The processed materials have stable photographic properties and few silver stains. The mercapto pyrimidine has the following structure ##STR1## wherein R.sub.1 and R.sub.2 each represents a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, a hydroxyl group, a mercapto group, a carboxyl group, a sulfo group, a phosphono group, a nitro group, a cyano group, a halogen atom, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, a sulfamoyl group or an alkoxy group. The sum of the carbon atoms contained in R.sub.1 and R.sub.2 is from 2 to 20. R.sub.1 and R.sub.2 may be bonded to each other to form a ring structure.
