PROBLEM TO BE SOLVED: To provide a curable composition for inkjet, in which storage stability can be increased and heat resistance of a cured product can be increased.SOLUTION: The curable composition for inkjet is to be applied by an inkjet system and cured by irradiation with light and by heating. The curable composition for inkjet comprises a polyfunctional compound having two or more (meth)acryloyl groups, a compound having a cyclic ether group, a photopolymerization initiator, a thermosetting agent, and a polymerization inhibitor that is different from a phenolic polymerization inhibitor. In the measurement of a viscosity of the curable composition for inkjet under the conditions of 25°C and 1 rpm in accordance with JIS K2283, a ratio of a viscosity after heated at 80°C for 24 hours in an environment not in contact with oxygen to a viscosity before heating is 1.2 or less. |
