Abstract
An improved process of cast coating and the coating composition used therein produces a paper coating which has exceptional brightness, gloss, smoothness, flexibility, resistance to drum adhesions and pick resistance. The paper coating is especially effective in cast coating where extremely high smoothness and gloss is essential. The paper coating composition utilizes soy protein binder which has been modified by copolymerization to add a synthetic component to modify the properties of the soy protein.
