光カチオン硬化性組成物
Document Type and Number:
Japanese Patent JP7367933
Kind Code:
B2
Abstract:
To provide a photocationically curable composition which rapidly cures during light irradiation without causing gelatinization even if stored at a high temperature or room temperature for a long time in a photocationically curable composition having small polymerization shrinkage.SOLUTION: There is provided a photocationically curable composition obtained by adding a photoacid generator (b) for generating an acid having a dissociation constant in water of -4 or less such as a diaryl iodonium salt-based compound composed of diphenyliodonium and perchlorate and a photoacid generator (c) for generating an acid having a dissociation constant in water of -3 or more such as an ion pair compound of diphenyliodonium and methanesulfonate to a cationic polymerizable monomer (a) such as a compound having a cyclic siloxane structure having an epoxy functional group.SELECTED DRAWING: None
