| abstract |
The invention relates to aqueous pigment preparations containing at least one organic and/or inorganic pigment, as well as dispersing agent that comprises or more structural units of the formula (I) n n n n n n n n n n which are bound to a structural unit Y. In formula (I), a represents an integer from 1 to 100, b represents an integer from 0 to 100, c represents an integer from 1 to 100, units a, b, and c can be arranged statistically or in blocks, R 2 represents an aliphatic, linear or branched hydrocarbon radical having 1 to 30 carbon atoms, A represents hydrogen or an anionic radical of the formulae —SO 3 M, —SO 2 M, —PO 3 M 2 , —CH 2 COOM or (II), and n n n n n n n n n n n n M represents a hydrogen atom, a cation from the group Na + , K + , NH 4 + , ethanolammonium, diethanolammonium or triethanolammonium, or a secondary, tertiary or quaternary, alkyl-substituted ammonium ion that is substituted with alkyl groups, or a combination thereof. Structural unit Y represents a carbon-containing structural unit which can alkoxylate at least at two bonding points that are formed by one or several nitrogen atoms, one or more oxygen atoms, or both. |
