ABSTRACT:
Metal particles used as a color producing component in powder coating compositions are individually encapsulated in a thin and continuous coating of thermoplastic, organic film-former prior to mixing with the particulate, organic, material which serves as the principal film-former of the powder coating composition. The coated particles are prepared by spray drying a solution of a controlled amount of the thermoplastic material in a volatile solvent in which the metal has been dispersed. In a preferred embodiment, the coating thus achieved on the metal particles is of the same composition as the principal film-former of the powder coating composition.
