substratos revestidos e dispersões de polímero adequados para uso na obtenção dos mesmos. a presente invenção refere-se a um substrato revestido compreende um substrato e um revestimento sobre pelo menos uma superfície do substrato. o revestimento compreende um pré-polímero, um polímero ou uma resina produzidos, por exemplo, pela reação de (i) um isocianato (por exemplo, um poliisocianato), (ii) um corante com terminação de hidrogênio ativo e opcionalmente (iii) pelo menos um reagente selecionado do grupo que consiste em agentes de aumento de cadeia, poliôis, tensoativos internos e combinações dos mesmos. as dispersões de polímero adequadas para uso na obtenção de tais substratos revestidos compreendem um tal pré-polímero, um polímero ou uma resina. 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.
