Abstract
Reaction product of a composition comprising in admixture a polyisocyanate, a silicone having dimethylsiloxane segments containing one or more isocyanate-reactive group, a reactant containing one or more of an isocyanate-reactive group and one or more ionizable group, optionally an organic substance having one or more isocyanate-reactive groups and no ionizable group, and compound providing counterion for said ionizable group, wherein either the silicone, or the reactant, or both, have a single isocyanate-reactive group.
