ABSTRACT:
A method of forming a colored polymer coating on a substrate is disclosed which comprises mixing a reactive polymer, a reactive colorant, and a linking agent, and reacting the linking agent with the reactive polymer and reactive colorant under suitable conditions to form the colored polymer coating. The polymer from which the coating is formed has reactive groups which can react with the linking agent. The reactive colorant has the general formula:
