Abstract

See full text

An aqueous resin dispersion with which excellent adhesiveness to a polyolefin base material such as a polypropylene base material can be easily obtained, which can be baked at low temperature, and which is for producing an aqueous coating material; and an aqueous coating material and an adhesive which contain the aqueous resin dispersion, are provided. In an aqueous resin dispersion (C) of the present invention, an olefin polymer (A) and a polymer (B) containing a constitutional unit derived from a radically polymerizable monomer (b1) having a reactive functional group are dispersed in an aqueous medium, a median diameter of the aqueous resin dispersion (C) measured by a dynamic light scattering method is 300 nm or less, and a dry product of the aqueous resin dispersion (C) contains 1 mass % or more of an insoluble component (D) that is insoluble in tetrahydrofuran.
