PROBLEM TO BE SOLVED: To provide a cationic polymerization catalyst composition overcoming the influence of a residual acid without deteriorating the curability and cured product properties of a cationically polymerizable compound and a curable resin composition containing the same. To do. SOLUTION: A photocationic polymerization initiator or a thermal cationic polymerization initiator, an acidic substance generated from the cationic polymerization initiator at the time of cationic polymerization, undergoes a neutralization reaction after completion of the curing reaction to form an insoluble or hardly soluble compound in water or an organic compound. From a compound insoluble or hardly soluble in water or an organic compound to be formed (for example, an alkaline earth metal salt compound such as calcium, magnesium and strontium) and a cationic polymerizable compound such as an oxirane compound such as an epoxy compound or an oxetane compound, a curable resin Prepare the composition. |
