Abstract
An aqueous based topcoating formulation is provided to coat various substrates such as those used in offset and electrographic printing devices. The water based coating formulation includes ethylene acrylic acid copolymer, polyethyleneimine, and a suitable crosslinker. The formulation exhibits excellent adhesion to substrates and excellent anchorage with different printing inks.
