Abstract

A process for the preparation of a graft copolymer which comprises reacting (I) a hydrocarbon resin based on cyclopentadiene or methylcyclopentadiene or both at an elevated temperature with (II) an olefinically unsaturated polycarboxylic acid compound and (III) a copolyerisable unsaturated monomer in a manner such that for at least a part of the reaction the unsaturated monomer (III) and the polycarboxylic acid compound (II) are simultaneously present, a graft-polymer based on I. a hydrocarbon resin based on cyclopentadiene or methylcyclopentadiene or on both as essential monomers, II. olefinically unsaturated polycarboxylic acid compounds and III. copolymerisable unsaturated monomers and a printing ink which comprises, as at least part of the binder component, said polymer, a pigment and a solvent.
