Abstract
A water-based primer coating for use on paper and polymeric substrates is provided for enhancing the adhesion of liquid toner to the substrates, which are designed to be printed using an electrophotographic printing device. The primer coating includes an aliphatic polyurethane dispersion and an anionic wax emulsion, and is substantially free of copolymers of ethylene and acrylic acid.
