Pigment preparations based on perylene compounds

Claim 1

Pigment preparations comprising a) as the base pigment at least one perylene compound of the general formula I ##STR14## in which A is a bivalent radical --O-- or >NR 1 and B is a bivalent radical --O-- or >NR 2 , D is a chlorine or bromine atom, and if n>1, optionally a combination thereof, and n is a number from 0 to 4; in which, in the above radicals A and B, then R 1 and R 2 independently of one another are each a hydrogen atom or a C 1 -C 4 -alkyl group, or a phenyl group, which can be unsubstituted or mono- or polysubstituted by halogen, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, or phenylazo; and b) as the pigment-dispersing agent at least one perylene compound of the general formula II ##STR15## in which V is a bivalent radical --O--, >NR 3 or >N--R 4 --Y - X + and W is the bivalent radical >N--R 4 --Y - X + , D is a chlorine or bromine atom, and if n>1, optionally a combination thereof, and n is a number from 0 to 4; in which, in the above radicals V and W, then R 3 is a hydrogen atom or a C 1 -C 18 -alkyl group, or is a phenyl group, which can be unsubstituted or mono- or polysubstituted by halogen, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy or phenylazo, R 4 is a C 1 -C 18 -alkylene group, which can be interrupted once or several times within the C--C chain by a bridge member from the series --O--, --NR 5 --, --S--, phenylene, --CO--, --SO 2 -- and --CR 6 R 7 --, or a chemically appropriate combination thereof, and in which in turn the constituents R 5 , R 6 and R 7 independently of one another are each a hydrogen atom or a C 1 -C 4 -alkyl group, which can be unsubstituted or substituted by a heterocyclic radical, or is a phenylene group, which can be unsubstituted or mono- or polysubstituted by C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy, Y - is one of the anionic radicals --SO 3 - or --COO - and X + is the hydrogen ion H + or the equivalent ##EQU8## of a metal cation from main group 1 to 5 or from subgroup 1 or 2 or 4 to 8 of the periodic table of the chemical elements, in which m is one of the numbers 1, 2 or 3; or is an ammonium ion N + R 8 R 9 R 10 R 11 , in which the substituents R 8 , R 9 , R 10 and R 11 on the quaternary nitrogen atom independently of one another are each a hydrogen atom or one of the following radicals: C 1 -C 30 -alkyl, C 1 -C 30 -alkenyl, C 5 -C 30 -cycloalkyl, unsubstituted or C 1 -C 8 -alkylated phenyl or a (poly)alkylenoxy group ##STR16## in which R 8 is hydrogen or C 1 -C 4 -alkyl and k is a number from 1 to 30, and in which alkyl, alkenyl, cycloalkyl, phenyl or alkylphenyl designated as R 8 , R 9 , R 10 and/or R 11 can also optionally be substituted by amino, hydroxyl and/or carboxyl; or in which the substituents R 8 and R 9 , together with the quaternary nitrogen atom, can form a five- to seven-membered saturated ring system, which optionally also contains further hetero atoms; or in which the substituents R 8 , R 9 and R 10 , together with the quaternary nitrogen atom, can form a five- to seven-membered aromatic ring system, which optionally also contains further hetero atoms and to which additional rings are optionally fused.
