Abstract
Provided is a cationic curing agent including porous particles and a mixture carried on the porous particles. The mixture includes a compound represented by Formula (1) below in which R1 to R3 are identical and R1 to R6 are identical and a compound represented by Formula (1) below in which at least one of R1 to R6 is different. In Formula (1), R1 to R3 are each an optionally branched alkyl group having from 1 to 18 carbon atoms, or a phenyl group that may have a substituent, and R4 to R6 are each a hydrogen atom, an optionally branched alkyl group having from 1 to 4 carbon atoms, a halogenoalkyl group, an alkoxy group, or a phenoxy group that may have a substituent.
