Description

technical field

[0001] The present invention relates to an oxime ester compound, which is characterized in that it is an esterified derivative of arylene pentacyclopentadione oxime, and the esterified oxime group is at the 2-position, which has the use as a photoinitiator in a photocurable composition. Background technique

[0002] Oxime ester compounds have been discovered as photoinitiators very early. Both US3558309 and US4255513 patents have disclosed oxime ester compounds as photoinitiators. However, the oxime esters of some structures have poor thermal stability or low sensitivity, so it is difficult to Thermal stability, sensitivity and other properties meet the requirements of the modern electronics industry. CN1514845A discloses a series of oxime ester compounds, and two varieties OXE01 and OXE02 are on the market. Products with similar properties include oxime esters 305 and 304 disclosed in CN101565472B and CN101508744B.
