Zusammenfassung:PROBLEM TO BE SOLVED: To provide a dispersion liquid of a polymer for an aqueous coating, capable of providing an aqueous coated material excellent in weather resistance over a long period and not exfoliating from a substrate.SOLUTION: A dispersion liquid of a polymer is produced by emulsion-polymerizing a monomer mixture (A) containing 0.1 to 2.0 mol% of a monomer (a1) having two or more radical polymerizable groups, and a monomer (a2) having a specific structure represented by 1-methyloxy-2,2,6,6-tetramethyl-4-methacryloyloxypiperidine, 1-propyloxy-2,2,6,6-tetramethyl-4-methacryloyloxypiperidine or the like.
