  • VISIBLE LIGHT-CURING OF PHOTOCURABLE COMPOSITIONS IN AMBIENT ATMOSPHERE
    Publication number: 20170022350
    Abstract: A photocurable composition is curable by exposure to visible light, and comprises a free-radical polymerizable compound and a photoinitiating system, the photoinitiating system comprising a) a dye which is excitable by visible light and has a triplet energy form 150 kJ/mol to 250 kJ/mol, such as Eosin Yellow and Fluorescein, and b) an ?-halogen carbonyl compound. Preferably, the composition comprises a compound with a C—H-acidic hydrogen atom adjacent to at least one carbonyl group. The composition is cured by visible light in an oxygen-containing atmosphere and results in tack-free, colorless coatings.
