Abstract

A process for developing irradiated radiation-sensitive recording materials using an aqueous-alkaline developer which contains compounds of the formula (I) ##STR1## wherein A is H, Na, K, NH.sub.4 or NR.sub.4, where PA1 R is a substituted or unsubstituted alkyl radical, PA1 W and X, independently of one another are H or --CH.sub.2 --COOA, PA1 Y is H or COOA and PA1 Z is H or OH, wherein the compound of the formula (I) contains at least 3 COOA units.
