Abstract:
Disclosed are α-keto oxime ester carbazole derivatives with a specific aroyl chromophore useful as a photo initiator, as well as photopolymerizable compositions comprising said photo initiator and ethylenically unsaturated compounds. The photopolymerizable compositions are useful, for example, in photoresist formulations for display applications, e.g. liquid crystal display (LCD), organic light emitting diode (OLED) and touch panel.
