Patent ID: 7763679

Claim:
A coating composition when applied over a resinous substrate produces an adherent coating thereon, said composition comprising: (a) a crosslinkable component comprising a polymeric mix containing at least one crosslinkable copolymer polymerized from a monomer mixture comprising one or more ethylenically unsaturated monomers having on average 1 to 10 hydroxyl groups and a saturated hydrocarbon polymer, wherein said monomer mixture comprises in the range of from 70 parts to 99 parts of said ethylenically unsaturated monomers and 1 part to 30 parts of said saturated hydrocarbon polymer, all in parts by weight based on 100 parts by weight of said crosslinkable component; and (b) a crosslinking component comprising cycloaliphatic polyisocyanate of the formula: R 1 —(R 2 —NCO) n wherein R 1 is a substituted or unsubstituted cycloaliphatic group containing about 3 to 20 carbon atoms in the ring, R 2 is independently selected from a direct bond, a straight aliphatic group or branched aliphatic group, wherein said aliphatic group has from 1 to 6 carbon atoms, and wherein n ranges from 2 to 10.
