| Abstract: | Disclosed are an alkoxysilyl-containing A-B block copolymer formed from
(meth)acrylate monomers as constituent monomers, characterized in that a
polymer block of A chain has a number average molecular weight (Mn) of
from 1,000 to 50,000 and a molecular weight distribution (Mw/Mn) of not
greater than 1.6, a polymer block of B chain comprises
alkoxysilyl-containing (meth)acrylate units as constituent monomer units,
and the A-B block copolymer as a whole has a molecular weight
distribution of not greater than 1.6, a process for the production of the
block copolymer, a resin-treated pigment, and a pigment dispersion. |
