PHOTOSENSITIZER AND VISIBLE LIGHT CURABLE RESIN COMPOSITION USING THE PHOTOSENSITIZER, AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a visible light-sensitive resin composition which has sufficient sensitivity in the visible light region, especially for argon laser and the second high harmonics of YAG laser, has excellent storage stability, and can form excellent photosensitive layers for visible light laser. SOLUTION: This photosensitizer using one or more azaindoline compounds of general formula 1, concretely for example, a compound of structural formula (1-1), and the visible light-curable resin composition containing the photosensitizer.
