Abstract: To provide an actinic-ray-curable ink composition that has high flowability and can thus achieve superior gloss on printed matter.
The actinic-ray-curable ink composition which contains a compound having an ethylenically unsaturated bond and epoxidized oil or fat is employed, wherein the epoxidized oil or fat has a peroxide value of 1 meq/kg or more. Such epoxidized oil or fat can be prepared through epoxidation of, for example, waste edible oil after being used in cooking fried foods by a known means. Accordingly, the present invention can achieve not only the object described above but also the effective utilization of waste.
