Disclosed are anthraquinone dyes useful in conventional dyeing of synthetic fibers and for incorporation by copolymerization into polyesters for coloring the same, said dyes having the structure ##STR1## wherein R is --OH, --COOR.sup.1, or --COX wherein R.sup.1 is --H or a radical such as lower alkyl which may be used in polyester forming condensation reactions, X is halogen, preferably Cl or Br, n is 1 or 2, either A or B of II must contain, and A or B of I may contain, at least one additional ##STR2## group, and each of rings A and B may be substituted with 1-3 radicals such as lower alkyl, cycloalkyl, lower alkoxy, chlorine, bromine, amino, lower alkyl amino, substituted lower alkyl amino, aryl amino, lower alkylsulfonyl, lower alkylthio, arylthio, and the like. The term "lower " as used herein means 1-6 carbons. These dyes can be used for conventional dyeing of a variety of fibers including polyester, polyamide, and cellulose ester, in addition to dyeing polymers by incorporation into the molecule, and are particularly useful for imparting red to greenish-blue shades to polyester plastics materials such as bottles when employed in the proper combinations.
本发明涉及一种蒽醌染料,可用于合成纤维的传统染色,也可通过共聚合并入聚酯中进行着色。该染料的结构为:##STR1## 其中R为—OH,—COOR.sup.1或—COX,其中R.sup.1为—H或类似较低烷基的基团,可用于聚酯形成缩合反应,X为卤素,优选为Cl或Br,n为1或2,II中的A或B必须包含,并且I中的A或B可以包含至少一个额外的##STR2##基团,环A和B中的每一个都可以用1-3个较低烷基,环烷基,较低烷氧基,氯,溴,氨基,较低烷基氨基,取代较低烷基氨基,芳基氨基,较低烷基磺酰基,较低烷基硫醇基,芳基硫醇基等基团进行取代。在本文中,“较低”一词的含义是1-6个碳原子。这些染料可用于各种纤维的传统染色,包括聚酯,聚酰胺和纤维素酯,此外还可通过将其并入分子中对聚合物进行染色,特别适用于在适当的组合下赋予聚酯塑料材料(如瓶子)红色到绿蓝色调。
