Zusammenfassung: | Pigment preparations consisting of organic pigments and basic additives of the general formula I (Q-A)xY(I) in which Q is a radical of the formula II (II) in which R1 is halogen, an alkyl, alkoxy or cyano group, R2 is halogen, m and n are integers from 0 to 4, A is a chemical bond or a divalent group from the series consisting of -(CH2)p-, -CR3R4+13, arylene, -S-, -O- and -NR5-, in which p is an integer from 1 to 12, R3 is hydrogen or alkyl, R4 is alkyl and R5 is hydrogen or alkyl, Y is a tertiary nitrogen atom or a group in which R6, R7 and R8 are alkyl or alkenyl or a cycloaliphatic or araliphatic radical or an alkyleneheteroaryl radical, or Y is a saturated or unsaturated heterocyclic radical in which at least one tertiary nitrogen atom is included in the meanings mentioned for Y and x is a number from 1 to 6. |
