ABSTRACT:
A paper coating composition has therein an optical brightening agent (OBA) and a water-soluble non-ionic polysaccharide derivative, exhibiting a solution viscosity in water of less than 1500 cps when dissolved at 5% polymer concentration, wherein the paper coating provides improved optical brightness as compared to the same formulation without said non-ionic, polysaccharide derivative. A paper coated with this composition has an optical brightness value of greater than 70.
