| Popis: |
The invention relates to pigment preparations containing (a) at least one organic or inorganic pigment; (b) at least one cyclic imide of general formula (1) wherein R represents a linear-chain, branched or cyclic aliphatic radical having 10 to 30 - preferably 12 to 25 - carbon atoms, or an alkenyl radical having 10 to 30 - preferably 12 to 25 - carbon atoms, the aforementioned radicals being able to be substituted by at least one, e.g. 2, 3, 4 or 5, substituent from the group consisting of C1-C6-alkyl, C1-C6-alkoxy, C6-C10-aryl, hydroxy, carboxy, and sulfo, R, R, R and R are the same or different and represent hydrogen, C1-C10-alkyl, C1-C10-alkoxy, halogen, OR, NRR, -COOR, -CONRR, -NR-COR, SO2NRR, -SO3M, -NO2, -CN or CF3, R and R representing H or an alkyl radical having 1 to 10 C atoms and M representing an equivalent of a cation having a valency of 1 to 3; and (c) optionally further standard additives. |
