Abstract
Abstract WHEREIN P and Q are alkylene; R, S, and T are hydrogen or alkyl; and l, m, and n are positive integer. The resin compositions are usable in paint, ink, and the like, and are particularly useful in preparing toner for use in electrophotography, such as by dispersing coloring agents therein. Resin Compositions comprising 30 to 85% by weight of polystyrene and/or styrene copolymers, 5 to 68% by weight of chlorinated paraffins having at least 30% by weight chlorine content, and 2 to 24% by weight of at least one aromatic compound selected from those having the following formulae:
