  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.

  本发明提供了一种红色染料，其具有至少一个聚（氧烷基）链连接到1位的色团，以及至少一个聚（氧烷基）链连接到蒽醌骨架的5位或8位。这种染料表现出优异的碱稳定性、有效的着色性、优异的低萃取率和高耐光性水平，特别是当其纳入某些介质和/或在某些基底表面，特别是聚酯上时。聚（氧烷基）链还增加了在不同溶剂或树脂中的溶解性，从而允许在不同介质和/或不同基底中引入这种优异的着色色团，并提供了一种易于处理的液态染料。本发明还提供了包含这种染料的组合物和物品，以及生产这种创新染料的方法。
