A process for coating a substrate, especially an automobile body, by spray application whereby improved resistance to 'sagging' or 'running' on application can be obtained without reduction of the thickness of film which is applied; the process is characterized by the use of a coating composition comprising a film-forming acrylic resin, a volatile organic liquid diluent, a pigment other than a metallic flake pigment, and specified polymer microparticles which are stably dispersed in the combination of the resin and the diluent.

Spray coating of acrylic resin comprising polymeric microparticles

Coating composition for spray application to a substrate comprising a film-forming polymer, a volatile organic liquid diluent, specified polymer microparticles stably dispersed in the combination of the film-forming polymer and the diluent, and metallic pigmentation also dispersed in the said combination. The composition affords improved control of the orientation of the metallic pigment.
