View Patent ↗The present invention provides a curable composition comprising a compound having a partial structure represented by the following formula (I) and a partial structure represented by the following formula (II): wherein in formula (I), A represents a group capable of forming a four- or more-membered bivalent alicyclic alkyl group with neighboring carbon atoms; and in formula (II), R 1 represents an alkylene, a cycloalkylene, or an arylene group, and n represents an integer of 1 or more.
1. A curable composition comprising a polymerizable compound represented by one of the following compounds of (1) to (7), (9) to (13) and (17):
further comprising a compound that generates acid by irradiation of a radiation ray,
wherein the compound that generates acid by irradiation of a radiation ray is at least one compound selected from the compounds represented by the following formulas (b1), (b2) and (b3):
in formula (1),
R 201 , R 202 and R 203 each independently represents an organic group; and
X − represents a non-nucleophilic anion;
in formulas (b2) and (b3),
R 204 to R 207 each independently represents an aryl, alkyl or cycloalkyl group; and
X − represents a non-nucleophilic anion.
2. The curable composition according to claim 1 , further comprising a compound selected from an epoxy compound, a vinylether compound, and an oxetane compound which is not included in said polymerizable compounds.
3. An ink composition comprising the curable composition according to claim 1 .
4. The ink composition according to claim 3 , further comprising a colorant.
5. The ink composition according to claim 4 , wherein the colorant is a pigment or an oil soluble dye.
6. The ink composition according to claim 5 , wherein the oxidation potential of the oil soluble dye is 1.0 V (vs. SCE) or more.
7. The ink composition according to claim 3 , wherein the ink composition is used for inkjet recording.
8. An inkjet recording method comprising: ejecting the ink composition of claim 3 onto a recording medium by an inkjet recording apparatus; and then curing the ejected ink composition by irradiation of an active radiation ray.
9. The inkjet recording method according to claim 8 , wherein the active radiation ray is an ultraviolet ray irradiated from a light-emitting diode that emits an ultraviolet ray having an emission peak wavelength in the range of 350 to 420 nm and a maximum illuminance of 10 to 2,000 mW/cm 2 on the recording medium surface.
