  • Photoinitiator composition containing acylcarbazole derivative and carbazolyl oxime ester, and use thereof in photocurable composition
    Patent number: 11947259
    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.

  • Polyacrylate macromolecular photoinitiator, synthesis method therefor and use thereof
    Patent number: 11608395
    Abstract: A polyacrylate macromolecular photoinitiator, a synthesis method therefor, and the use thereof. The polyacrylate macromolecular photoinitiator is free of a component having a molecular weight of less than 1000, and can effectively avoid the introduction of a material having a mall molecular weight in the photoinitiator and the odor and migration contamination produced thereby, the general formula thereof being as shown in formula I.
