Novel diaroyl carbazole compounds and their applications as sensitizers

摘要

The present invention provides a novel diaroyl carbazole compound used in a photoresist composition together with a carbazolyl oxime ester photoinitiator to exhibit a remarkable synergistic initiation effect, so that the molar ratio of the diaroyl carbazole compound to the carbazolyl oxime ester photoinitiator is In the case of 0.1 to 1.4, an optimal sensitization effect is exhibited.
