Kurzfassung englisch:
Photopolymerization of (meth)acrylate-based formulations has become a widespread method for many industry sectors due to the high energy efficiency and low curing times of this technology. Common industrial radical photoinitiators generally contain the benzoyl-chromophore as the key constituent. In medical or food packaging applications, residual photoinitiator or photoproducts migrating into the packaged product have to be avoided. Degradation and recombination products of aromatic initiators are potentially mutagenic or toxic to the human body.1-2 So non-aromatic photoinitiators are of high interest for industrial applications. Therefore a new generation of initiator systems, based on α-ketoesters, was developed.3 Compared to the classical benzophenone-amine photoinitiator systems, the α-ketoesters show increased reactivity and higher curing speed. The photoproducts of α-ketoesters were considered harmless to humans.
