Pigment preparations consisting of organic pigments and basic additives of the general formula I EQU (Q-A).sub.x Y (I) in which Q is a radical of the formula II ##STR1## in which R.sup.1 is halogen, an alkyl, alkoxy or cyano group, R.sup.2 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 --(CH.sub.2).sub.p --, --CR.sup.3 R.sup.4 --, arylene, --S--, --O-- and --NR.sup.5 --, in which p is an integer from 1 to 12, R.sup.3 is hydrogen or alkyl, R.sup.4 is alkyl and R.sup.5 is hydrogen or alkyl, Y is a tertiary nitrogen atom or a group ##STR2## in which R.sup.6, R.sup.7 and R.sup.8 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.
