Problems solved by technology

However, these photoinitiators have more or less low sensitivity (high polymerization rate and exposure dose), poor solubility (more transparency and photolithographic residue), low storage stability, insufficient short-wavelength sensitivity, Defects such as poor selectivity to specific photopolymerizable monomers, which affect the performance of photosensitive materials as a whole

Description

technical field [0001] The present invention relates to the use of a carbazole oxime ester compound as a photoinitiator in a photopolymerizable acrylate composition, the above photopolymerizable acrylate composition containing the carbazole oxime ester compound, and its application . Background technique [0002] Photocuring refers to the curing process of monomer, oligomer or polymer matrix under light induction. This technology has a wide range of applications in modern microelectronics technology, such as photocurable ink, liquid crystal panel packaging, photosensitive printing plate, Filters and photoresists, etc. The core of photocuring technology lies in photocurable polymerized monomers and suitable photoinitiators. Under the irradiation of ultraviolet / visible light, X-ray or laser at a certain wavelength, the photoinitiator generates active groups, which excites the unsaturated groups in the polymerizable monomer to undergo polymerization reaction, thereby causing ...
