The UV-crosslinking as an established technology has been used in many industrial manufacturing processes. New application and technical specifications of UV-crosslinking lead to continuous development of tailor-made photoinitiators which can efficiently meet specific requirements. A new class of radical reactive photoinitiators based on s-triazine has been used for crosslinking of acrylic pressure-sensitive adhesives containing double bonds. (C) 2011 Wiley Periodicals, Inc.
