PHOTOINITIATOR AND PHOTOSENSITIVE COMPOSITION INCLUDING THE SAME

摘要

Provided is a photoinitiator represented by Formula 1:;;The photoinitiator is suitable for photocrosslinking. Further provided is a photosensitive resin composition including the photoinitiator. The photoinitiator and the photosensitive resin composition have improved solubility and high sensitivity. The photosensitive resin composition is suitable for use in the production of black resists, color resists, overcoats, column spacers, and organic insulating films for LCDs.
