<P>PROBLEM TO BE SOLVED: To provide an acrylic-fluorine compound polymer particle suitable for an aqueous fluororesin coating, capable of reducing remarkably a fluorine content, capable of forming a coating film of excellent weather resistance, even when reducing remarkably a cost, and capable of restraining glossiness of the obtained coating film from getting low. <P>SOLUTION: The acrylic-fluorine compound polymer particle contains (A) a vinylidene fluoride polymer portion containing at least one kind of fluoro-olefin unit selected from the group comprising a tetrafluoroethylene unit, a hexafluoropropylene unit and a chlorotrifluoroethylene unit, as structural units, and a vinylidene fluoride unit, and (B) an acrylic polymer portion containing a (meth)acrylic monomer unit, and an ethylenic unsaturated group-containing monomer unit having an ultraviolet absorption portion or an ethylenic unsaturated group-containing monomer unit having a light stabilization portion, and a content of the vinylidene fluoride polymer portion (A) is 50 mass% or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
