Patent ID: 8062761

Claim:
A multi-layer coating, comprising: a primer surfacer a pigmented basecoat; and a clearcoat applied over the basecoat, wherein the primer surfacer is formed from a primer coating composition comprising: a film forming binder and an organic liquid carrier, and optionally pigment in a pigment to binder weight ratio of about 1:100-150:100; and wherein said film forming binder contains about: (a) 50 to 90% by weight, based on the weight of the binder, of a film-forming acrylic polymer component comprising two acrylic polymers, the first being a caprolactone-modified branched acrylic polymer and the second being a caprolactone-modified linear acrylic polymer, the polymers being provided in a relative weight ratio of from about 5:95 to 95:5; and (b) 10 to 50% by weight, based on the weight of the binder of a crosslinking agent selected from the group consisting of aminoplast resin, blocked polyisocyanates, and mixtures thereof; wherein the caprolactone-modified branched acrylic polymer is composed of caprolactone and at least one monoacrylic monomer and at least one diacrylic or dimethacrylic monomer.
