Novel leather articles comprise a substrate and a coating applied to a surface of the substrate. The coating comprises a prepolymer or resin. The prepolymer or resin can be produced, for example, by the reaction of (i) an isocyanate, (ii) at least one reactant selected from the group consisting of chain extenders, polyols, and combinations thereof, and (iii) an active hydrogen-terminated colorant. The active hydrogen-terminated colorant comprises a chromophore and an active hydrogen-terminated constituent bound to the chromophore. Novel methods for producing leather articles using active hydrogen-terminated colorants are also provided.
