Abstract:
1. A pigment dispersant of the general formula (I) in which Q s is a number from 1 to 5; n is a number from 0 to 4; the sum of a and n being from 1 to 5; R R E where the substituents R 9 , R 10 , R 11 and R 12 independently of one another are each a hydrogen atom, C 1 -C 30 -alkyl, C 2 -C 30 -alkenyl, C 5 -C 30 -cycloalkyl, phenyl, (C 1 -C 6 )-alkyl-phenyl, (C 1 -C 4 )-alkylene-phenyl or a (poly)alkyleneoxy group of the formula —[CH(R 80 )—CH(R 80 )—O] k —H, in which k is a number from 1 to 30 and the two radicals R 80 independently of one another are hydrogen, C 1 -C 4 -alkyl or, if k is >1, a combination thereof; and in which alkyl, alkenyl, cycloalkyl, phenyl or alkylphenyl R 9 , R 10 , R 11 , and/or R 12 may be substituted by amino, hydroxyl and/or carboxyl; or where the substituents R 9 and R 10 , together with a quaternary nitrogen atom, form a five- to seven-membered saturated ring system containing, optionally, further heteroatoms selected from the group consisting of O, S and N; or where the substituents R 9 , R 10 and R 11 , together with a quaternary nitrogen atom, form a five- to seven-membered aromatic ring system, containing, optionally, further heteroatoms selected from the group consisting of O, S and N, and to which, optionally, additional rings may be fused; or in which E + and/or G + defines an ammonium ion of the formula (Ia) in which R q is a number from 1 to 10; p is a number from 1 to 5, where p is ≦q+1; T is a branched or unbranched C
