Abstract An improved coating composition containing chlorinated polyolefin to provide superior orientation of metallic pigment flakes in the coating. The invention is particularly useful in the pigmented base coat of a base coat-clear coat coating since it permits the use of a thinner base coat which, because of the improved orientation of the metallic pigment flakes, provides superior hiding or masking of the coated substrate. The coating composition comprises a solvent, a film forming resin selected from the group consisting of acrylic, alkyd, polyester and polyurethane resins, a uniformly dispersed pigment and a chlorinated polyolefin. The multilayer coating composition comprises a base coat comprising a film forming resin selected from the group consisting of acrylic, alkyd, polyester and polyurethane in a solvent, a uniformly dispersed pigment and a chlorinated polyolefin, and a topcoat comprising a transparent coating composition deposited on said basecoat, said topcoat comprising a second film-forming resin selected from the group consisting of acrylic, alkyd polyester and polyurethane resin dispersed in a volatile organic solvent.
A multilayer coating composition comprising (A) a base coat, said base coat comprising a film-forming resin selected from the group consisting of acrylic, polyester and polyurethane in a solvent, a pigment uniformly dispersed in the base coat and a chlorinated polyolefin; and, (B) a top coat comprising a transparent coating composition deposited on said base coat, said top coat comprising a second film-forming resin selected from the group consisting of acrylic, polyester and polyurethane resin dispersed in a solvent.
