摘要：

In a sequence of reactions the activated thiocyanate derivative 2 was used to synthesize new Hansa Yellow dyestuffs embodying two heterocyclic moieties. The structure of the dyes was inferred from spectral and analytical data. Spectral behaviour of the dyes indicated that they existed essentially in the hydrazoneform (5-C). Dyeings of the compounds on polyester were assessed with a view to evaluating the percentage reflectance of the dyed fibre at different wave-lengths in the visble region and the Kubelka-Munk equation was used to calculate the K/S function of the dyed materials.
