    Abstract: Compounds of the formula ##STR1## wherein each R.sub.1 is alkyl of 1 to 3 carbon atoms, andA is phenylene, substituted phenylene, diphenylene, substituted diphenylene or naphthylene, wherein each substituent of substituted phenylene is independently fluoro, chloro, bromo, methyl, methoxy, ethoxy, trifluoromethyl or cyano and each substituent of substituted diphenylene is independently chloro, bromo, methyl or methoxy,With the proviso the two CO--O--R.sub.1 groups on each ring are meta or para to each other. These compounds are eminently suitable as pigments for the mass pigmentation of synthetic polymers and resins such as polyethylene, polystyrene, polyvinyl chloride, poromerics and rubber latices.

    Abstract translation: 其中每个R 1是1至3个碳原子的烷基,A是亚苯基,取代的亚苯基,二亚苯基,取代的亚二苯基或亚萘基,其中取代亚苯基的每个取代基独立地是氟,氯,溴,甲基, 甲氧基,乙氧基,三氟甲基或氰基,取代的二亚苯基的每个取代基独立地为氯,溴,甲基或甲氧基。本发明提供了每个环上的两个CO-O-R 1基团。 这些化合物特别适用于合成聚合物和树脂(如聚乙烯,聚苯乙烯,聚氯乙烯,poromerics和橡胶胶乳)的质量着色的颜料。
