Abstract
Abstract An emulsion coating composition and a substrate coated therewith. The aqueous phase of the coating contains a blend of resinous materials, one resin component, such as casein, forming a matrix structure and the other, such as an acrylic polymer, forming an essentially continuous film. The coating after drying contains small air-binder interfaces which scatter light. The resin components making up the binder may be chosen to give the coating a wide range of physical and chemical properties.
