To provide a print that can be authenticated by a simple operation.SOLUTION: A print according to the embodiment has an image formed on one surface of its substrate, which image includes a first pattern comprising a first color material layer and a second pattern comprising a second color material layer. The adhesive strength between the first color material layer and the substrate is larger than the adhesive strength between the second color material layer and the substrate. A protective layer may further be formed on the one surface of the substrate to cover the image. The adhesive strength between the first color material layer and the substrate is larger than the adhesive strength between the first color material layer and the protective layer; the adhesive strength between the second color material layer and the substrate is smaller than the adhesive strength between the second color material layer and the protective layer.SELECTED DRAWING: Figure 1 【課題】簡単な作業で真贋判定を行える印画物を提供する。【解決手段】本実施形態に係る印画物は、基材の一方の面に第１色材層からなる第１パターン及び第２色材層からなる第２パターンを含む画像が形成されたている。前記第１色材層と前記基材との接着力は、前記第２色材層と前記基材との接着力より大きい。前記画像を覆うように前記基材の一方の面に形成された保護層をさらに備えてもよい。前記第１色材層と前記基材との接着力は、前記第１色材層と前記保護層との接着力より大きく、前記第２色材層と前記基材との接着力は、前記第２色材層と前記保護層との接着力より小さい。【選択図】図１
