Title:
POLYMERIZATION INITIATOR, POLYMERIZABLE COMPOSITION, CURED PRODUCT AND HYDROPEROXIDE HAVING THIOXANTHONE SKELETON
Document Type and Number:
WIPO Patent Application WO/2023/190161
Kind Code:
A1
Abstract:
The present invention provides a polymerization initiator (A) which contains a dialkyl peroxide (a-1) that has a thioxanthone skeleton represented by general formula (1) and a hydroperoxide (a-2) that has a thioxanthone skeleton represented by general formula (2), wherein the content of the hydroperoxide (a-2) that has a thioxanthone skeleton is 30 parts by mass or less per 100 parts by mass of the polymerization initiator (A). This polymerization initiator exhibits excellent curability with respect to light having a wavelength of 365 nm or the like, while having excellent long-term storage stability at high temperatures.
