Abstract
Polymeric compounds for lithographic printing plates, especially plates for use in printing utilizing UV curable inks, may include a structural unit (I) wherein R1 represents an optionally-substituted cyclic or alkyl group, x represents 0 or 1 and A represents an optionally-substituted alkylene group. A range of compounds having different solubilities in selected solvents may be prepared by varying the identity or group R1. Such components may be prepared by reacting an amine of formula R1NH2 with the maleic anhydride derivative corresponding to moiety 1.
