Quinacridones having selectively adjusted triboelectric effects, which quinacridones contain about 0.05% to 100 percent by weight of triboelectrically active compounds of the general formula I Image (I), in which Q is a quinacridone radical which is unsubstituted or substituted by halogen atoms, alkyl, alkoxy, H2N-CO-, alkyl-NH-CO- or (alkyl)2N-CO groups, A is a direct bond or -O-, -S-, -NR1-, -CO-, -SO2-, -CR2R3- or arylene and Y is an -NR4R5 group or a five-, six- or seven-membered heterocycle which contains one to three heteroatoms from the series comprising nitrogen and/or oxygen and/or sulfur and which can be substituted by alkyl, alkoxy, hydroxyphenyl, halogen, -CN, -COOH, -CO- NRR', -SO2-NRR', hydroxyalkyl or alkylaminoalkyl, in which R and R' together with the nitrogen atom can be a hetero- cycle, R and R' are hydrogen atoms or alkyl and R1 to R5, independently of one another, are each hydrogen and/or alkyl or alkenyl of 1 to 22 carbon atoms and n is a number from 1 to 4, and their use for the preparation of toners or developers which are used for electrophoto- graphic copying or reproduction of originals and for printing electronically, optically or magnetically stored information or are used in color proofing.
