Although radiation curing is an established technology used in many industrial manufacturing processes, new applications and technical challenges stimulate the development of tailor-made photolatent catalysts. The development of a new bisacylphosphine oxide (BAPO) photoinitiator enables the efficient curing of coatings stabilized with a light stabilizer package consisting of a UV-absorber and a hindered amine light stabilizer (weather-resistant coatings for outdoor applications). Tailor-made photolatent catalysts represent a key feature in the development of new electronic applications like laser direct imaging for the production of printed circuit boards, color filters for liquid crystal displays used in computer flat screens and chemically amplified photoresists for microelectronics.
