Abstract
A metallic tone powder coating composition of acrylic resin series which prises a polymer-capsulated metal powder composite material wherein a vinyl monomer is chemically combined with a powder of a metal such as aluminum and a copolymer having a glass transition temperature of at least 20.degree. C wherein the sum of an acrylic ester and a methacrylic ester is at least 30% by weight of the total monomer constituting the copolymer. This powder coating composition provides a coating film having excellent weather-resistance and beautiful appearance and is suited for use in electrostatic powder spraying.
