Patent ID: 7098257

Claim:
A coating material, curable thermally or thermally and with actinic radiation, comprising (A) at least one binder selected from the group consisting of polyaddition resins, polycondensation resins, addition (co)polymers of olefinically unsaturated monomers, and combinations thereof, wherein the polyaddition resin is at least one of random, alternating, or block, and the polyaddition resin is linear or branched, and the binder is curable thermally or thermally and with actinic radiation; and (B) from 1.5 to 3% by weight, based on the solids of the coating material, of at least one polyisocyanate which is free from blocking agents and is blocked internally by uretdione groups so that the at least one polyisocyanate is blocked up to a deblocking temperature of at least 160° C., wherein the at least one polyisocyanate has a free isocyanate content, as measured by DIN EN ISO 11909, below 1.0% by weight.
