Recyclable and compostable coated paper stock (10) comprising a substrate (12) coated on at least one surface with a primer coat (14) and a top coat (16) both of which are water based dispersions. The primer coat (14) comprises a water based dispersion of a polymer selected from the consisting of acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, poly-ethylene vinyl acetate, poly-ethylene vinyl chloride, styrene butadiene copolymers, polyvinylidiene chloride and starch. The top coat (16) comprises a water based dispersion of a polymer selected from the group consisting of acrylic polymers, acrylic copolymers, styrene butadiene copolymers and polyvinylidiene chloride. The substrate (12) is coated with a primer coat (14) prior to the application of the top coat (16) to seal the substrate (12) surface. The top coat (16) forms a film over the primer coat (14) and imparts water and grease resistant properties to the coated paper stocks (10). The invention also includes processes for making and using the invented coated paper stocks (10). |
