Spray coating of acrylic resin comprising polymeric microparticles

摘要

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.
