Abstract
A hot melt wax coating composition and hot melt wax coated paper product are provided which coating contains at least one chemical compound which is either itself capable of acting as a latent dispersant for the coating or capable of being chemically modified so as to act as a dispersant for the coating, within an aqueous environment, thus rendering the hot melt coating more readily dispersable from the coated paper. The coated paper product is repulpable using standard paper mill equipment.
