  • Patent number: 6121351
    Abstract: Thermoplastic compositions containing certain anthraquinone polysulfonamide colorants incorporated therein as toners or colorants. The anthraquinone colorant moieties which are incorporated into the polymer chain of the polysulfonamide colorants are not leachable, sublimable or extractable and do not exude from the thermoplastic compositions. The anthraquinone polysulfonamide colorants may be added to the thermoplastic polymers during production or melt blended with the polymer by conventional techniques to produce transparent thermoplastic compositions useful for a variety of end uses where nonmigrating or nonextractable colorants are needed.
