摘要： Curable compositions based on polyuretidiones, polythiols and photoactivable bases are disclosed. Also a process for generating isocyanate groups by exposing uretidiones to radiation in the range of 100-315 nm is disclosed. The process can be used in a dual curing system for curing compositions that comprise groups that under go photoinduced polymerizations and active hydrogen groups that react with the generated isocyanates.
