  The dyestuffs are prepared by diazotation of an amine, reaction with a pyridone coupling component carrying in the 3-position a 5- or 6-membered heterocyclic ring containing an o-nitrogen and an o-sulphur or second nitrogen atom and quaternisation. A further carbocyclic or heterocyclic ring may be fused to the first. The novel pyridone coupling components carry a 3-benzimidazole or a 3-benzthiazole substituent and are made by reacting a 3-cyano pyridone with an o-phenylene diamine or o-aminothiophenol in the presence of anhydrous aluminium trichloride. The dyestuffs colour acrylic materials bright yellow shades of high tinctorial strength. They have good fastness properties and compatibility values.

  染料的制备方法是：重氮化胺，与在 3 位上含有一个 5 或 6 元杂环的吡啶酮偶联组分反应，该杂环含有一个邻氮和一个邻硫或第二个氮原子，然后进行季铵化反应。另一个碳环或杂环可与第一个碳环或杂环融合。新型吡啶酮偶联组分带有 3-苯并咪唑或 3-苯并噻唑取代基，是通过 3-氰基吡啶酮与邻苯基二胺或邻氨基苯硫酚在无水三氯化铝存在下反应制成的。 这些染料能使丙烯酸材料染上明亮的黄色，具有很高的锡宽容度。它们具有良好的牢度特性和相容性。
