Abstract
New photocationic photoinitiator combinations are described that consist of 2,4,6-triarylpyrylium salts with non-nucleophilic anions and electron donors, that are able rapidly to crosslink unpigmented as well as pigmented mixtures based on cycloaliphatic epoxides to form colourless layers such as lacquers and printing inks without generating interfering and toxic emissions.
