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.
