Alpha-ketoxime ester carbazole derivatives having specific aroyl chromophores for use as photoinitiators are disclosed, as well as photopolymerizable compositions comprising the photoinitiators and ethylenically unsaturated compounds. The photopolymerizable compositions are useful, for example, in photoresist formulations for display applications such as Liquid Crystal Displays (LCDs), Organic Light Emitting Diodes (OLEDs), and touch panels. |
