9,10-BIS(LONG CHAIN ACYLOXY)ANTHRACENE COMPOUND, PRODUCTION METHOD THEREOF AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a photo-cationic polymerization sensitizer which can sensitize an iodonium salt or a sulfonium salt, a photo-cationic polymerization initiator, in a photo-cationic polymerization and which a cured product of a photo-cationically polymerizable composition with high transmittance.SOLUTION: A photo-cationic polymerization sensitizer contains a 9,10-bis(long chain acyloxy)anthracene compound represented by formula (1) which ic obtained by acylation of a compound of formula (2). (In reaction formula 1, R represents a 5-12C alkyl group; and X and Y may be the same or different and represents a hydrogen atom or a 1-8C alkyl group).
