Title:
PHOTOACID GENERATOR, AND PHOTOSENSITIVE COMPOSITION USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/130796
Kind Code:
A1
Abstract:
Provided are: a photoacid generator that effectively generates acid even when there is a high concentration of a substance such as a colorant that attenuates or shields irradiated light, and even when the film thickness is great and a light source is visible light to infrared light, in particular, infrared light with low energy; and a highly curable photosensitive composition using the photoacid generator. The present invention is a photoacid generator that is a metal complex having, as a ligand, a ring structure formed by bonding five-membered ring aromatic heterocyclic compounds directly or by π-conjugation, wherein a central metal has one or two axial ligands, and the axial ligand has an onium salt structure.
