To provide acryl-fluorine composite polymer particles, which can secure water resistance even by a forced drying method and which can reduce the amount of fluororesin while maintaining weather resistance and chemical resistance, and to provide an aqueous coating material composition using the particles.
The acryl-fluorine composite polymer particles comprise: a vinylidene fluoride polymer (A)containing, as structural units, at least one type of a fluoroolefin unit selected from a group consisting of a tetrafluoroethylene unit, a hexafluoropropylene unit and a chlorotrifluoroethylene unit, and a vinylidene fluoride unit; and a crosslinkable acrylic polymer (B) containing a (meth)acrylic acid ester unit (b1) which is compatible with the vinylidene fluoride polymer (A), a (meth)acrylic acid ester unit (b2) which is incompatible with the vinylidene fluoride polymer (A), and a (meth)acrylic monomer unit (b3) having a crosslinkable group cross-linkable by heating. The mass ratio of vinylidene fluoride polymer (A)/crosslinkable acrylic polymer (B) is 10/90 to 90/10.
