Abstract: Oil and grease resistant paper products are disclosed that include a substrate and, on at least one side of the substrate, a continuous layer of a barrier coating, the barrier coating comprising a binder system and a pigment. The barrier coating, when applied to the substrate and dried to form a barrier layer, has a Pigment Volume Concentration (PVC) that is below a Critical Pigment Volume Concentration (CPVC) of the barrier coating, providing a continuous three-dimensional film of the binder system. In some implementations the binder system comprising a latex and a natural binder and/or the paper product further includes a topcoat disposed on a side of the barrier coating opposite the substrate.

Abstract: A coated printing sheet is provided that is suitable for conventional offset printing grades, exhibiting desirable surface and optical properties and providing a surface that is image receptive and resistant to coating failure. The coated printing sheet includes an image receptive coating containing a hard polymer pigment having a shear modulus of at least 5.0×109 dynes/cm2 and a film forming binder. The coated printing sheets resist burnishing and exhibit desirable properties, e.g., gloss, bulk, stiffness and smoothness, with minimal or no calendering.
