More Information
Summary:The present invention relates to: a polymer particle in which a urethane resin (A1) and an acrylic polymer (B1) are included in a single particle, said polymer particle having a gel fraction of 10% or more as measured using N,N-dimethylformamide (DMF) as a solvent; a polymer particle in which a urethane resin (A2) having a sulfonic acid group and an acrylic polymer (B2) are included in a single particle, said polymer particle having a surface acid value of 0.1 to 19 mgKOH/g as measured by a potentiometric titration method; and a method for producing a polymer dispersion. According to the present invention, it becomes possible to provide: a polymer dispersion which has excellent polymerization stability and can have an excellent coating viscosity property and excellent storage stability when used in a coating material; a method for producing the polymer dispersion; and a polymer particle contained in the polymer dispersion. It also becomes possible to provide: a coating material which enables the formation of a coating film that can have excellent water resistance and solvent resistance even when the drying conditions include a low temperature and a shorter drying time; and a coated material which has the coating material applied thereon.
