  • Patent number: 6635350
    Abstract: Red colorants comprising a chromophore having at least one poly(oxyalkylene) chain attached to the 1-position, as well as at least one poly(oxyalkylene) chain attached to either the 5-position or the 8-position of an anthraquinone backbone are provided. Such colorants exhibit excellent base stability, effective colorations, excellent low extraction rates, and high lightfastness levels, particularly when incorporated within certain media and/or on the surface of certain substrates, particularly polyesters. The poly(oxyalkylene) chains also increase the solubility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and/or diverse substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such colorants are provided as well as methods for producing such inventive colorants are also provided.

  • Patent number: 6593483
    Abstract: Blue colorants comprising a chromophore having at least one poly(oxyalkylene) chain attached to the 1- position, the 4- position, or both, through aromatic amino group or groups, of an anthraquinone backbone are provided. Such colorants exhibit excellent amine/base stability and thermal stability, effective colorations, excellent low extraction rates, and high lightfastness levels, particularly when incorporated within certain media and/or on the surface of certain substrates, particularly polyesters, polyolefins, and polyurethanes. The poly(oxyalkylene) chain or chains can be conveniently tailored to increase the solubility or compatibility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and/or or diverse substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such colorants are provided as well as methods for producing such inventive colorants.
