Embodiments of the present disclosure are directed to primer coatings, polymeric substrates, and methods of producing thereof, which provide enhanced adhesion and enhanced chemical and water resistance properties. The primer coatings comprise functionalized styrene-butadiene and ink adhesion promoter.

Ink receptive primer coatings with improved water and chemical resistance characteristics

A laminate structure is provided which includes a first polymeric substrate laminated to a second polymeric substrate. A primer coating comprising the reaction product of polyethyleneimine and formaldehyde is included on the surface of the first polymeric substrate which is subsequently printed with an ink or toner image prior to lamination to the second polymeric substrate. The primer coating provides good toner and/or ink adhesion to the polymeric substrate. The primer coating also provides improved bond strength upon lamination of the first and second polymeric substrates as well as providing water resistance to the laminate structure.

Laminate structure including a primer coating therein

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.
