ABSTRACT:
The invention provides a coating composition that provides high brightness, high gloss and superior print quality. The coated product comprises a substrate coated on at least one side with a coating composition comprising a pigment component and a binder component that is made of mixture of two binder resins. Both binder resins are capable of film forming. The first binder resin provides coating gloss and adhesion properties and the second binder resin enhances coating porosity, adhesion, and anti-static properties. The first binder resin that is used at 60-95% by weight of the total binder resin blend is selected from the group consisting of vinyl acetate acrylate, styrene acrylate and styrene butadiene acrylic copolymers. The second binder resin that is used at 5-40% by weight of the total binder resin blend is selected from the group consisting of anion type polystyrene derivatives, polyethylene glycol and polypropylene glycol.
