Disclosed are anthraquinone dyes useful for incorporation by copolymerization into polyesters which may be used, for example, to mold colored beverage bottles. The dyes are copolymerized with the polyester, are thermally stable at the temperatures used to process the polyesters, and are color-fast and nonextractable from the polyester. The dyes have the general formula:
wherein either or both of rings A and B may contain in any position thereon one or two groups of the formula
R and R3 each is hydrogen or lower alkyl;
R', R2, R4 and R5 each represents 0-3 substituents selected from lower alkyl; lower alkyl substituted with lower alkoxy, phenyl, Cl, Br or lower alkanoylamino; lower alkoxy; lower alkoxy substituted with lower alkoxy, phenyl, Cl, Br, or lower alkanoylamino; chlorine; bromine; amino; lower alkyl amino; lower alkylamino substituted with lower alkoxy, cyclohexyl, phenyl, Cl, Br, or lower alkanoylamino; arylamino; arylthio; aroylamin; wherein each aforesaid aryl moiety is 6-10 carbons; lower alkylsulfonyl; lower alkylthio; lower alkanoylamino; and cyclohexylamino; and n and m are each 1 or 2.
所公开的蒽醌染料可通过共聚掺入聚酯中,例如用于模塑有色饮料瓶。这些染料可与聚酯共聚,在加工聚酯的温度下具有热稳定性,并且不变色,也不能从聚酯中析出。染料的通式如下
其中环 A 和环 B 的任一环或两环可在其上的任何位置含有一个或两个式中的基团
R 和 R3 各为氢或低级烷基;
R'、R2、R4 和 R5 各代表 0-3 个取代基,这些取代基选自低级烷基;被低级烷氧基、苯基、Cl、Br 或低级烷酰氨基取代的低级烷基;低级烷氧基;被低级烷氧基、苯基、Cl、Br 或低级烷酰氨基取代的低级烷氧基;氯;溴;氨基;低级烷基氨基;低级烷基氨基;被低级烷氧基、环己基、苯基、Cl、Br 或低级烷酰氨基取代的低级烷基氨基;芳基氨基;芳硫基;芳基氨基;其中每个上述芳基的碳原子数为 6-10 个;低级烷基磺酰基;低级烷硫基;低级烷酰氨基;和环己基氨基;以及 n 和 m 各为 1 或 2。
