Abstract
A cationically polymerizable composition is provided, which comprises a cationically polymerizable compound, a cationic polymerization initiator, and a specific tertiary alkanolamine or tertiary alkylamine. The cationically polymerizable compound is preferably an alicyclic epoxy compound and an oxetane compound. The above amine accounts for 0.01 to 1.0% by weight, preferably 0.05 to 0.5% by weight of the total of the cationically polymerizable composition and the cationic polymerization initiator accounts for 0.1 to 20 parts by weight based on 100 parts by weight of the cationically polymerizable compound. The composition is excellent in storage stability and dispersion stability of colorants contained therein.
