Coating compositions, including high degree of substitution (DS), viscosity optimized starches, are disclosed for use in non-barrier paper coatings. Paper coated with the same is disclosed as well as methods of making the coating compositions and coated papers.

Paper coating composition with highly modified starches

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&times;10 dynes/cm 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.
