<p>Provided is an actinic-radiation curable composition which has excellent actinic-radiation sensitivity and which, even when irradiated with actinic radiation in an oxygen-containing atmosphere, can provide a cured coating film having hardness equivalent to that attained when irradiated therewith in a nitrogen atmosphere. Further, the actinic-radiation curable composition can provide a cured coating film which has excellent hardness, moisture resistance, heat resistance, and chemical resistance. A composition which comprises (a) isosorbide di(meth)acrylate, (b) a polymerizable unsaturated compound other than the component (a), and (c) an initiator for actinic-radiation polymerization and in which the contents of the components (a) and (b) are each 5 to 95 parts by mass per 100 parts by mass of the sum total of the components (a) and (b), and the content of the component (c) is 0.1 to 20 parts by mass per 100 parts by mass of the sum total of the components (a) and (b).</p> |
