ABSTRACT OF THE DISCLOSURE Disclosed are anthraquinone dyes useful in conventional dyeing of synthetic fibers and for incorporation by copolymeriza- tion into polyesters for coloring the same, said dyes having the structure Image I and Image II wherein R is -OH, -COOR1, or -COX wherein R1 is -H or a radical such as lower alkyl which may be used in polyester forming condensation reaction, X is halogen, preferably Cl or Br, n is 1 or 2, either A or B of 11 may contain, and A or B of 1 may contain, at least one additional Image group, and each of rings A and B may be substituted with 1-3 radicals such as lower alkyl, cycloalkyl, lower alkoxy, chorine, 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.
