Abstract
A coated substrate comprises a substrate and a coating on at least one surface of the substrate. The coating comprises a prepolymer, polymer, or resin produced, for example, by the reaction of (i) an isocyanate (e.g., a polyisocyanate), (ii) an active hydrogen-terminated colorant, and optionally (iii) at least one reactant selected from the group consisting of chain extenders, polyols, internal surfactants, and combinations thereof. Polymer dispersions suitable for use in making such coated substrates comprise such a prepolymer, polymer, or resin.
