Abstract
(EN)
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).

Papier (10) enduit et recyclable compostable, comprenant un substrat (12) enduit sur au moins l'une de ses faces d'une couche d'accrochage (14) et d'une couche de revêtement (16), ces deux couches étant l'une et l'autre des dispersions à l'eau. La couche d'accrochage (14) est une dispersion à l'eau constituée d'un polymère choisi parmi les polymères acryliques, les copolymères acryliques, l'acétate de polyvinyle, l'alcool de polyvinyle, l'acétate de poly éthylène-vinyle, le chlorure de poly éthylène-vinyle, les copolymères de styrène butadiène, le chlorure de polyvinylidiène et l'amidon. La couche de revêtement (16) est constituée d'une dispersion à l'eau d'un polymère choisi dans le groupe comprenant les polymères acryliques, des copolymères acryliques, les copolymères styrène butadiène et le chlorure de polyvinyldiène. Le substrat (12) est enduit d'une couche d'accrochage (14) avant de subir l'application de la couche de revêtement (16) étanchéifiant la surface de ce substrat (12). La couche de revêtement (16) constitue un film par dessus la couche d'accrochage (14) et confère des propriétés de résistance à l'eau et à la graisse à ce papier enduit (10). L'invention porte également sur les procédés de réalisation et d'utilisation de tels papiers enduits (10).
