Abstract
A polyurethane is formed from an isocyanate and a polyester diol having a molecular weight less than about 2000, or a polyester diol comprising two polyester diol segments connected by a steric hindrance group, each of the polyester diol segments having a molecular weight less than about 2000. The polyurethane is useful as a binder in electro-optic displays, and in components used to form such displays.
