Abstract

Linear quinacridones are made by condensing a salt of the general formula <FORM:0997476/C4-C5/1> wherein X is sodium or potassium and R1 is an aryl radical which may be substituted by halogen, alkyl, alkoxy, aryloxy, acylamino or aryl, with polyphosphoric acid having a content of phosphorus pentoxide in the range of 83 to 86% at a temperature in the range of 120 DEG to 140 DEG C. Examples are given. Specifications 828,052, 851,976, 868,360, 948,487, 951,451 and 976,553 are referred to.
