Abstract Coatings from blends of cycloaliphatic epoxides and vinyl ethers were cross‐linked by UV‐induced cationic photopolymerization. The conversion of the vinyl double bonds during postcuring was followed by NIR reflection spectroscopy. The effect of various parameters such as the composition of the reactive formulation or the applied radiation dose on the kinetics of the postcuring process was studied. Finally, it was demonstrated on a pilot‐scale curing line that NIR spectroscopy can be used for inline monitoring of the actual conversion in UV‐cured coatings from cationic photopolymers.
