| abstract |
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 1 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 C 1 -C 6 -alkyl, C 1 -C 6 -alkoxy, C 6 -C 10 -aryl, hydroxy, carboxy, and sulfo, R 2 , R 3 , R 4 and R 5 are the same or different and represent hydrogen, C 1 -C 10 -alkyl, C 1 -C 10 -alkoxy, halogen, OR 6 , NR 6 R 7 , —COOR 6 , —CONR 6 R 7 , —NR 6 —COR 7 , SO 2 NR 6 R 7 , —SO 3 M, —NO 2 , —CN or CF 3 , R 6 and R 7 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. |
