Abstract: Quinophthalone dyes of the formula in which X denotes O or NC-C>>-R, where R is cyano, optionally N-substituted carbamoyl, carboalkoxy, quinazolonyl, quinoxalinonyl, benzimidazolyl or benzothiazolyl and the rings A, B, the quinoline system and/or the condensed benzo systems are optionally substituted by non-solubilising groups. In paints, printing inks and plastics, especially in thermoplastics, the dyes (I) give clear colours with good fastness properties, coupled with good temperature resistance.
