Abstract
Copolymers of dimethylaminopropyl methacrylamide and hydroxyethyl methacrylate having residual monomer levels of <2000 ppm and <500 ppm, respectively, are made by copolymerizing the monomers in a predetermined weight ratio in an aqueous-alcoholic solvent of defined composition. Substrates coated with these copolymers are capable of absorbing the solvents, e.g. water or organic solvents, of digital printing inks rapidly with dry times of <1 min.
