The present invention provides oxime ester phenylcarbazole compounds useful as photoinitiators in photo-crosslinking reactions. (C 1 -C 20 ) alkyl group or (C 6 -C 20 ) allyl group directly bonded to the nitrogen atom of the oxime ester structure. The compound according to the present invention and the photopolymerizable composition containing the same are excellent in solubility, excellent in photosensitivity, excellent in residual film ratio, pattern stability and adhesion to resist, and therefore can be used for black resist, color resist, overcoat, column spacer, useful. |
