ABSTRACT:
The present invention discloses a novel polyurethane composition useful as a dispersing binder. The binder yields magnetic dispersions having high gloss values. Moreover, the polyurethane provides excellent hydrolytic stability. The polyurethane comprises a polyol, a diisocyanate a chain extender and an functional modifier formed of a reaction product of an aminodiol and Bronsted Acid.
