    • 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.
    • 提供了包含具有至少一个连接到1-位的聚(氧化烯)链的发色团的红色着色剂以及连接到蒽醌主链的5-位或8-位的至少一个聚(氧化烯)链 。 这些着色剂表现出优异的碱稳定性,有效着色,优异的低提取速率和高耐光性水平,特别是当结合到某些介质和/或某些基材,特别是聚酯的表面上时。 聚(氧化烯)链还增加了在不同溶剂或树脂中的溶解度,从而允许在不同的介质和/或不同的基底内引入这些优异的着色发色团,并提供便于处理的液体着色剂。 提供了包含这种着色剂的组合物和制品,并且还提供了制备这种本发明着色剂的方法。
