Abstract
A thermally curable ink-jet ink includes a compound having a thermally curable functional group and a gelling agent. The thermally curable ink-jet ink undergoes a sol-gel phase transition depending on temperature.
Claims4
A thermally curable ink-jet ink comprising:
- a compound having a thermally curable functional group;
- a gelling agent;
- a compound having a photopolymerizable functional group;
- and
- a photopolymerization initiator,
- wherein the thermally curable ink-jet ink undergoes a sol-gel phase transition depending on temperature, and
- wherein the compound having the thermally curable functional group is (a) a polyfunctional isocyanate compound having an isocyanate group protected by a thermally dissociable blocking agent, or (b) a (meth)acrylate compound having an imide group,
- wherein the gelling agent is at least one compound selected from compounds represented by the following general formula (G1) or (G2):
- R1—CO—R2 General formula (G1):
- R3—COO—R4 General formula (G2):
- wherein R1 to R4 each independently represent an alkyl chain having a linear portion having 12 or more carbon atoms and optionally having a branch.
