(57) [Summary] [Structure] A liquid photopolymerization initiator in which two or more kinds of iodonium salt compounds represented by the general formula <A> are mixed and which can be easily and uniformly dispersed in a resin, and one or more kinds of cationic polymerization. It is a photopolymerizable resin composition containing a resin. [Chemical 1] (In the formula, R 1 and R 2 are a halogen atom, a haloalkyl group, a nitro group, a sulfone group, an amino group, a hydroxyl group, a cyano group, an alkyl group, an alkenyl group, an alkoxy group, a substituted or unsubstituted cycloalkyl group, and an aromatic group. A cyclic group or a heterocyclic group (including a condensed ring), which may be the same or different, m and n are integers from 0 to 5. X -1 represents an anion. ) [Effect] It is easily and quickly cured by irradiation with light at room temperature for a short time. |
