CA 2518138
The invention provides innovative blocked polyisocyanates whose crosslinking is initiated thermally and photochemically. The polyisocyanates comprise at least one thermally reversibly blocked NCO group whose blocking agent contains at least one group which on exposure to actinic radiation reacts, with polymerization, with ethylenically unsaturated compounds. A process for preparing the polyisocyanates, and their use in binders, is also provided.
