CA 2061356

Abstract the Disclosure Disclosed are metal-azo and metal-azomethine materials which are useful as monomeric dyes which may be mordanted by polymerization. The inventive dyes contain a central metal; an azo containing ligand; and a ligand having a free-radically polymerizable group (not directly attached to the azo or azomethine containing ligand) bound to the metal, and optionally, a monodentate or bidentate ligand which satisfy the coordination requirements of the central metal. Also disclosed are homopolymers and copolymers of the metal-azo or metal azomethine dyes.
