Pigment dispersions containing dispersants prepared by controlled radical polymerization and having pendent hydrophilic polymeric segments

A pigment dispersion comprising:

• (a) pigment;
• (b) an aqueous carrier selected from water and a mixture of water and at least one organic solvent;
• and
• (c) a pigment dispersant prepared by controlled radical polymerization, in the presence of a polymeric initiator having at least one radically transferable group, of a first monomer composition comprised of at least one radically polymerizable ethylenically unsaturated hydrophobic monomer and at least one radically polymerizable ethylenically unsaturated hydrophilic monomer,
• wherein said polymeric initiator forms a polymeric backbone segment, the first monomer composition forms polymeric segments pendant to said polymeric backbone segment, at least a portion of the hydrophilic monomer is located at an end of said pendant polymeric segment furthest from said polymeric backbone segment, at least a portion of said hydrophobic monomer is located at an end of the pendant polymeric segment nearest said polymeric backbone segment, and said polymeric backbone segment is hydrophobic.
