Patent ID: 10781328

Abstract:
A purpose of the present invention is to provide an actinic-ray-curable ink-jet ink that gives images of satisfactory quality at temperatures, the center of which lies in a moderate range and that, even when the temperature of the substrate changes to the higher-temperature or lower-temperature side, can give prints of satisfactory quality. The actinic-ray-curable ink-jet ink includes an actinic-ray-curable compound and a gellant. The gellant contains at least one C15-26 alkyl group. The actinic-ray-curable ink-jet ink contains a crystal nucleator, the crystal nucleator comprising a (poly)glycerin fatty acid ester compound A that comprises a (poly)glycerin skeleton and a C15 or higher alkyl group bonded to the (poly)glycerin skeleton. The content of the compound A is 1.0-10 mass % with respect to the total mass of the gellant.
