Abstract

Linear quinacridone dyes are made by heating a 2:5-diarylamino-terephthalic acid or an ester thereof in anhydrous hydrofluoric acid at a temperature within the range of 80 DEG to 200 DEG C. The terephthalic acid or ester may be substituted in the aromatic nuclei of the arylamino groups. The heating may be carried out in an autoclave. Examples are given.
