It was found that the bimolecular type photoinitiators consisting of N ‐phenylglycine and (thio)xanthene dyes exhibited high initiating efficiency on irradiation of visible light. From the time‐resolved spectroscopic study, the free radical is formed by the sensitized decarboxylation of N ‐phenylglycine in the presence of (thio)xanthene dye. By using these initiating systems, the visible laser sensitive photopolymer was prepared and the imaging characteristics were evaluated.
