Abstract
This invention relates to use of a copolymer of a high acid value macromonomer which is obtained through copolymerization of specific monomeric components including methacrylic acid in the presence of a metal complex which is a catalytic chain transfer agent or an addition cleavage-type chain transfer agent, and optionally a radical-polymerization initiator, or this macromonomer into which a polymerizable unsaturated group is further introduced, with an ethylenically unsaturated monomer; and said copolymer into which further a long chain alkyl group is introduced; as pigment-dispersing resins to be used in water-based paint.
