An improved coated paperboard or plate stock useful for forming substantially rigid food containers such as plates, bowls, trays and the like and a process from producing the improved coated paperboard are provided. A base coat comprising a styrene acrylic latex and a pigment is applied directly to the paperboard, and a top coat comprising a styrene acrylic polymer latex and a pigment is applied directly to the base coat to form the coated plate stock. The improved coated plate stock is characterized by improved grease, oil and cut resistance, improved varnish gloss, enhanced smoothness, and improved printing quality.

[ I claim:] [1.] A coated paperboard with a smooth, print-receptive finish suitable for forming disposable food service and food storage containers that are grease-resistant, oil soak-through resistant, and cut-resistant after the coated paperboard is subjected to the heat and pressure required to form the finished food containers, wherein a sized paperboard substrate with a basis weight suitable for forming a food service container or food storage container is coated with two layers of a coating composition consisting of:(a) a base coat coating layer immediately adjacent to and covering a sized surface of the paperboard substrate, said base coat coating layer comprising a mixture of a polymer latex and a particulate pigment comprising a blend of a premium grade kaolin clay and an ultrafine, wet ground calcium carbonate, said polymer latex and said pigment being approved for food contact by the U.S. Food and Drug Administration; and(b) a top coat coating layer immediately adjacent to and covering the base coat coating layer, said top coat coating layer comprising a mixture of a styrene acrylic polymer latex and a particulate pigment comprising a blend of a premium grade kaolin clay and an ultrafine wet ground calcium carbonate, said styrene acrylic polymer latex and said pigment being approved for food contact by the U.S. Food and Drug Administration.
