ABSTRACT:
By providing a dispersion system which incorporates hard waxes having high molecular weights and a melting point greater than 180.degree.F., a unique paper coating additive is achieved. Preferably, the wax is powdered to a particle size less than 50 microns, and is dispersed in a system compatible with typical paper coating colors. In the preferred embodiments, high molecular weight Fischer-Tropsch waxes are employed.
