<P>PROBLEM TO BE SOLVED: To provide a curable composition for ink-jet, long in pot life even in the inner environment of an ink-jet device heated at ≥50°C. <P>SOLUTION: The present invention relates to a curable composition for ink-jet, which is coated by an ink-jet method and is cured by applying heat. The curable composition for ink-jet comprises a compound having a cyclic ether group, a thermosetting agent, and a pigment. The thermosetting agent is a compound having a nitrogen atom. The pigment is a pigment exhibiting pH ≥3.0 and <7.3, when heating a liquid obtained by adding 5g of the pigment to 100 mL of pure water, boiling the liquid for 5 minutes, leaving the liquid until reaching 23°C to obtain the boiling-treated liquid, adding water to the obtained boiling-treated liquid in a water amount evaporated by the boiling-treatment to give the liquid containing 100 mL of water, and then measuring the pH of the liquid. <P>COPYRIGHT: (C)2012,JPO&INPIT |
