Abstract: An ink jet recording method includes the steps of ejecting an active-radiation-curable ink composition onto a recording medium by an ink jet process and curing the ejected ink composition by irradiation with active radiation. During transporting of the recording medium in the ejecting and curing steps, an unwinding stress in the recording medium is larger than a winding stress in the recording medium. The recording medium has a thickness of 10 μm to 100 μm. Also provided is a method for manufacturing laminated printed matter using printed matter produced by the ink jet recording method.

Abstract: A photopolymerization initiator which is a compound having a structure in which one or more carbonyl groups that link to a carbon atom are further directly bonded to an aromatic ring of an aromatic acyl group that bonds to a phosphorus atom in an acylphosphine oxide structure. A producing method of a photopolymerization initiator produces the photopolymerization initiator. In a polymerizable composition and an ink jet recording method, the photopolymerization initiator is used. Furthermore, an acylphosphine oxide compound has a partial structure represented by Formula 1 or Formula 2.
