<p>PROBLEM TO BE SOLVED: To provide an active energy ray curing-type composition and ink, each having good dispersibility of pigments, high storage stability and excellent curability. SOLUTION: 70 parts by weight of 3,4epoxycyclohexyl-3,4-epoxycyclohexan carboxylates (photocationic polymerizable resin), 30 parts by weight of triethylene glycol divinyl ethers (photocationic polymerizable resin), 4 parts by weight of a mixture (photocationic polymerization initiator) containing hexafluoro phosphates of triallyl sulfonium and propylene carbonates, and 1.5 parts by weight of Anti-terra-U (trade name, surfactant) are mixed under stirring at a room temperature in a dark room and thereby, ink 1 comprising KOH having an acid number of 36 mg is produced.</p> |
