Zusammenfassung:	PROBLEM TO BE SOLVED: 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.SOLUTION: 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.
