Abstract
A coating for paper comprising water, pigments, binder and poly(ethylene oxide). The binder comprising about 1 to 30 percent by weight of the dry weight of the pigments and the poly(ethylene oxide) comprising about 0.001 to 10 percent by weight of the dry weight of the pigments. The coating has a very low Brookfield viscosity. The poly(ethylene oxide) coating provides superior gloss and smoothness relative to conventional paper coatings and may be applied to the paper in higher coat weights. A process for using the poly(ethylene oxide) coating to make improved paper is also disclosed.
