A blue colorant comprising a chromophore having at least one poly(oxyalkylene) chain attached, through aromatic amino group (or groups), to the 1-position, the 4-position, or both, of an anthraquinone backbone is 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.
