Abstract:
Provided is a photoinitiator composition containing an acylcarbazole derivative and a carbazolyl oxime ester. The photoinitiator composition is used in a photocurable composition, especially a photoresist formulation, and exhibits the best sensibilization effect when the molar ratio of the acylcarbazole derivative to the carbazolyl oxime ester photoinitiator is between 0.1 and 1.4.
