(57) Summary [Objective] To provide a polymer composition which can be effectively used as a colorant for coating paper in order to impart an excellent balance of properties of the coated paper. A binder copolymer derived from a comonomer forming an α, β-ethylenically unsaturated carboxylic acid ester and a water-soluble homopolymer and optionally other comonomer, And α, β-ethylenically unsaturated carboxylic acid, α, β-ethylenically unsaturated carboxylic acid ester, ethylenically unsaturated carboxamide, cross-linking monomer, and optionally one or more copolymerizable monomers A polymer composition comprising an aqueous dispersion rheology control copolymer cross-linked to. |
