Abstract: WHEREIN R1 and R2 are identical or different and represent a hydrogen or halogen atom, an alkyl or alkoxy group having each 1 to 4 carbon atoms, an aryloxy, aryl, carbonamide or N-alkyl carbonamide group or which represent together the radical of an aromatic or heterocyclic ring, and 0.5 to 15 percent by weight of one or several linear trans-quinacridones of the general formula
WHEREIN Y represents a straight-chained or branched alkyl or alkoxy radical having 6 to 18 carbon atoms, m and n are integers of from 0 to 1 and the sum of n and m being 1 or 2 and R1 and R2 having the meanings given above. These mixtures are obtained by mixing with one another starting compound or final products substituted accordingly during the process of preparation or formation and processing in the manner usual for quinacridones. As compared to the single components the mixture thereof is more transparent and has a better color intensity, a better dispersability and fluidity of the lacquers colored with them and frequently more brilliant shades.
