ABSTRACT:
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.
