Photochemical reaction in three different water-developable flexographic printing plates was characterized. The distribution of photochemical reaction in the direction of thickness was evaluated by utilizing ¹³C NMR and IR (ATR) measurements, and the results obtained showed that the distribution of reaction as well as the overall reaction in the printing plates depends on the plate compositions. ¹H NMR analysis for soxhlet extracts of exposed samples showed that the reactivity of monomers depends on its structure and molecular weight in relating to a specified phase condition of the composition.
