Abstract:
Disclosed are oxime ester compounds which have specific benzo (unsaturated 5-membered ring)-carbonyl group and their use as photoinitiators in photopolymerizable compositions, in particular in photoresist formulations for display applications, e.g. liquid crystal display (LCD), organic light emitting diode (OLED) and touch panel.
