  • Patent number: 6667392
    Abstract: This invention relates to colorants comprising a chromophore having a single azo acetoacetanilide moiety, wherein said moiety each have at least one poly(oxyalkylene) chain. Such colorants exhibit extremely good base stability and lightfastness, particularly when incoporated within certain media and/or on the surface of certain substrates. These poly(oxyalkylene) chains provide solubility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and/or or diverse substrates. Compositions and articles comprising such colorants are provided as are methods for producing such inventive colorants.
