Patent ID: 8198370

Claim:
A substrate coated by a dried and cured layer of a coating composition wherein the coating composition comprises a crosslinkable component and a crosslinking component and wherein said crosslinkable component comprises at least three polymers, a linear or branched acrylic polymer A and a linear or branched acrylic polymer B and a linear or branched acrylic polymer C wherein; a) the linear or branched acrylic polymer A, having a weight average molecular weight in the range of from 1,000 to 40,000 and comprises in the range of from 10 to 25 percent by weight of primary hydroxy functional monomers; b) the linear or branched acrylic polymer B, has a weight average molecular weight in the range of from 1,000 to 40,000 and comprises in the range of from 0.5 to 5 percent by weight of primary or secondary amine functional monomers; and c) the linear or branched acrylic polymer C, has a weight average molecular weight in the range of from 1,000 to 40,000 and comprises in the range of from 5 to 25 percent by weight of secondary hydroxy functional monomers and monomers having primary hydroxy functional groups wherein the crosslinkable component comprises polymer A in the range of from 20 to 99 percent by weight, polymer B in the range of from 1 to 20 percent by weight, and polymer C up to 75 percent by weight, wherein the percentages are based on 100 percent by weight of the polymers A, B and C in the crosslinkable component.
