PHOTOACID PRODUCING AGENT AND VISIBLE RAY PHOTOSENSITIVE RESIN COMPOSITION BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a visible ray photosensitive resin composition having sufficient sensitivity in the visible ray region, especially for the second harmonic waves of a He-Cd laser, Ar laser and YAG laser and having superior storage stability. SOLUTION: In the visible ray photosensitive resin composition containing a visible ray photosensitive resin and a photoacid producing agent, the composition contains a dipyrromethene compound expressed by general formula (1) as the photoacid producing agent.
