Abstract
Provided herein is an aqueous polymer dispersion including A) a polymer synthesized from monomers including a) 1.0 to 90% by weight of at least one alkyl (meth)acrylate; b) 0.1 to 10% by weight of at least one ethylenically unsaturated acid or vinyl monomer with latent ionic groups; c) 0 to 5.0% by weight of at least one monoethylenically unsaturated monomer having at least one keto or aldehyde group; d) 1.0 to 90% by weight of at least one vinyl ester of saturated aliphatic monocarboxylic acid in which the carboxyl groups are attached to tertiary and/or quaternary carbon atoms; e) 0 to 20% by weight of at least one vinyl aromatics; and f) 0 to 20% by weight, based on the total amount of monomers for the synthesis of polymer A), of at least one hydroxyalkyl (meth)acrylate. Also included herein is an ink anchorage primer that enhances ink bonding.
