Patent ID: 6852771

Claim:
A coating composition comprising (a 1 ) a radiation curable component that polymerizes upon exposure to actinic radiation comprising (a 11 ) at least two functional groups comprising at least one bond that is activatable upon exposure to actinic radiation, (a 12 ) optionally, at least one isocyanate-reactive functional group, and (a 13 ) optionally, at least one hydroxyl-reactive functional group; (a 2 ) a thermally curable binder component that polymerizes upon exposure to heat comprising at least two functional groups (a 21 ) that are reactive with functional groups of component (a 3 ), wherein at least 5% up to 100% by weight based on a nonvolatile weight of component (a 2 ) is a component (X) that is a polymer with at least two functional groups (a 21 ), a glass transition temperature of less than 0° C., and an equivalent weight of greater than 225 grams per equivalent; (a 3 ) a thermally curable crosslinking component comprising at least two functional groups that are reactive with the functional groups (a 21 ); and (a 4 ) optionally, at least one reactive diluent, wherein the coating composition is curable upon exposure to both actinic radiation and thermal energy.
