Second generation 3-ketocoumarin photoinitiators: oligomeric and zero migration photoinitiators for LED curing
Marika Morone, IGM Resins S.r.l.
Abstract:Two years ago at RadTech 2016, IGM presented on novel ketocomarin photoinitiator chemistry. Now, following the launch of a first generation low migration ketocoumarin photoinitiator for LED cure (385/395 nm) for wood coatings and graphic arts, we will present further patented exploitations of this Type II photoinitiator type, with the objective of reaching a zero migration low yellowing system for multiple end uses in inks and coatings. We will present structural chemistry, scientific and applications data to underline the novelty and utility of this chemistry.
