    • 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) 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, R2 represents an aliphatic, linear or branched hydrocarbon radical having 1 to 30 carbon atoms, A represents hydrogen or an anionic radical of the formulae —SO3M, —SO2M, —PO3M2, —CH2COOM or (II), and M represents a hydrogen atom, a cation from the group Na+, K+, NH4+, 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.
    • 本发明涉及含有至少一种有机和/或无机颜料的水性颜料制剂,以及包含结构单元Y结合的式(I)结构单元或更多结构单元的分散剂。在式(I)中, a表示1〜100的整数,b表示0〜100的整数,c表示1〜100的整数,单位a,b,c可以统计排列或嵌段排列,R 2表示脂肪族,直链状或支链状 A表示氢或式-SO 3 M,-SO 2 M,-PO 3 M 2,-CH 2 COOM或(II)的阴离子基团,M表示氢原子,Na +,K + ,NH 4 +,乙醇铵,二乙醇铵或三乙醇铵,或被烷基取代的仲,叔或季烷基取代的铵离子,或其组合。 结构单元Y表示可以至少在由一个或多个氮原子,一个或多个氧原子或两者形成的两个键合点上烷氧基化的含碳结构单元。
