    • A pigment dispersion comprising pigment, an aqueous carrier selected from water and a mixture of water and at least one organic solvent, and a pigment dispersant is described. The pigment dispersant is prepared by controlled radical polymerization, e.g., atom transfer radical polymerization, and has polymer chain structure represented by the following general formula I, &phgr;-(G)p-(E)s-T  I In general formula I, G is a residue of at least one radically polymerizable ethylenically unsaturated monomer; E is a hydrophilic residue of at least one radically polymerizable ethylenically unsaturated monomer; G and E are different from one another; &phgr; is a hydrophobic residue of or derived from the initiator, and is free of said radically transferable group; T is or is derived from the radically transferable group of the initiator; p and s represent average numbers of residues occurring in a block of residues; p and s are each individually selected such that the pigment dispersant has a number average molecular weight of at least 250.
    • 描述了包含颜料,选自水和水与至少一种有机溶剂的混合物的水性载体和颜料分散剂的颜料分散体。 颜料分散剂是通过控制自由基聚合制备的,例如原子转移自由基聚合,并具有由以下通式I表示的聚合物链结构。通式I中,G是至少一个可自由基聚合的烯属不饱和单体的残基; E是至少一种可自由基聚合的烯属不饱和单体的亲水性残基; G和E是不同的; phi是引发剂的疏水性残基或衍生自引发剂,并且不含所述可自由基转移基团; T衍生自引发剂的可自由转移基团; p和s表示残基块中发生的残基的平均数; p和s各自独立选择,使得颜料分散剂的数均分子量至少为250。
