Zusammenfassung:Provided is a powder coating material composition which can be used to form a matte coating film having excellent finish, coating film hardness, weather resistance, and adhesion to a substrate. This powder coating material composition contains a binder component containing a hydroxy group-containing fluorocarbon resin (A), a polyester resin (B) having an acid value of 10 mgKOH/g or less and a hydroxy value of 10-100 mgKOH/g, and a blocked polyisocyanate (C); acrylic fine particles (D) having a volume-average particle size of 21-45 microns; and a color pigment (E). The powder coating material composition is characterized by containing, with respect to a total of 100 parts by mass of the solid contents of the binder component, 20-55 parts by mass of the component (A), 20-55 parts by mass ofthe component (B), 10-40 parts by mass of the component (C), 1-40 parts by mass of the acrylic fine particles (D), and 0.5-100 parts by mass of the color pigment (E). 本发明提供一种粉末涂料组合物,其能够形成光洁性、涂膜硬度、耐候性和对基材的粘附性优异的消光涂膜。一种粉末涂料组合物,
