Variable contrast print developers

In contrast, RT-FTIR spectroscopy allows a rapid and quantitative measurement of the conversion of specific reactive functional groups under variable conditions as light intensity, photoinitiator concentration, coating thickness, etc., which are closer matched to those in technical coating and printing processes. In the past, RT-FTIR spectroscopy has been successfully used to study the kinetics of photopolymerization reactions in dependence on the irradiation conditions and other experimental parameters, the reactivity of monomers and oligomers and the efficiency of newly developed photoinitiator systems.
