Abstract
Several novel pyrazolo[1,5‐a]pyrimidine derivatives containing two arylazo functions were synthesised from 4‐arylazo‐3,5‐diaminopyrazoles. Such derivatives were used as starting components. The characteristics of and the application properties of the dyes synthesised from 4‐arylazo‐3,5‐diaminopyrazoles were investigated and reported.
