Zusammenfassung:To provide a photosetting inkjet ink capable of forming a decorative sheet hardly generating reduction of clog at a nozzle or material compatibility, weak in odor, and hardly generating boundary surface breakage, aggregation breakage or the like even with combination with a protective layer consisting of a vinyl chloride resin, and the decorative sheet.SOLUTION: A photosetting inkjet ink contains a vinyl chloride and acetate-based resin, a radical polymerizable compound containing a radical polymerizable monomer represented by the formula (1), a photoradical polymerization initiator, and a coloring agent, forms a precursor layer of a pattern layer by an inkjet printing method and forms the pattern layer by irradiating a light and curing the precursor layer.SELECTED DRAWING: None 【課題】ノズルでの目詰まりやマテリアルコンパチビリティの低下などを生じにくく、臭気が弱い上、塩化ビニル系樹脂からなる保護層と組み合わせても界面破壊や凝集破壊等を生じにくい化粧シートを形成できる光硬化性インクジェットインクおよび化粧シート。【解決手段】光硬化性インクジェットインクは塩酢ビ系樹脂、式(1):で表されるラジカル重合性モノマーを含むラジカル重合性化合物、光ラジカル重合開始剤、着色剤を含み、インクジェット印刷法によって模様層の前駆層を形成し、光を照射して硬化させて模様層を形成する。【選択図】なし
