Abstract

A method is described for producing an imaged lithographic printing plate, wherein the developer comprises a hydrophilic polymer which comprises (m1) primary, secondary and/or tertiary amino groups, and (m2) acid groups selected from —COOH, —SO3H, —PO2H and —PO3H2, and (m3) optionally alkylene oxide units —(CHR1—CH2—O)p—, wherein R1 is H or —CH3 and p is an integer from 1 to 50.
