Pigment dispersions containing dispersants prepared by controlled radical polymerization |
摘要 |
A pigment dispersion which includes a pigment, an aqueous carrier and a pigment dispersant. The pigment dispersant is prepared by controlled radical polymerization initiated in the presence of a monomeric initiator having at least two radically transferable groups. The pigment dispersant has at least one of the following polymer chain structures:andwhere G is a hydrophobic residue of at least one radically polymerizable ethylenically unsaturated monomer; E is a hydrophilic residue of at least one radically polymerizable ethylenically unsaturated monomer; phi is a residue of or derived from the initiator, and is free of the radically transferable group; T is or is derived from the radically transferable group of the initiator; z is 2 to 10; p and s are at least one and are selected such that the pigment dispersant has a number average molecular weight of at least 500.
