    摘要: 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.

    摘要: Infrared (IR) radiation absorbing compounds of metal or metalloids with ligands are beneficial for many applications. Schiff base biquinone (SBB) ligands surrounding a metal or metalloid center may be used for laser welding applications, as one example, wherein effective infared radiation absorption and heat resistance are required. These compounds may be known as Schiff base biquinone metal complexes (SBBC's). The compositions and methods of this invention provide examples of many different NIR absorbing compounds that exhibit high NIR absorbing strength, good thermal stability, and relatively low visible color. The IR absorbing compounds may employ one or more of the following elements: Si, Zr, Bi, Sb, Ce, Cs, K, Mo.
