One of the most difficult problems encountered currently in the design of photosensitive systems in the field of UV curing and in the area of imaging science (such as 3-D stereolithography, photopolymers in laser-to-plate imaging systems, holographic recording films, or holographic optical elements) is to extend the spectral sensitivity of the photoinitiating system to the visible light emission. The design of efficient photosensitizer/photoinitiator combinations is partly based on a better understanding of the basic mechanism that is involved. The timeresolved laser absorption spectroscopy combined with steady state experiments appears as a very convenient tool to improve the efficiency of photoinitiating systems. The discussion centers on the excited state processes in selected examples of efficient photosensitive systems for laser-induced polymerization reactions that are of great practical use, e.g., in holographic recording or laser imaging.
