To provide a pressure-sensitive adhesive article in which damage to description information caused by peeling upon opening and abrasion after opening is reduced.SOLUTION: In a pressure-sensitive adhesive article 100 having a base material layer 10, a print layer 20 and a transparent adhesive layer 30 in this order, the print layer 20 has a pattern formation area 21 constituted of an inkjet ink, the pattern formation area 21 forms a pattern recognizable by comparison with a background part 22 of the base material layer 10 when the pressure-sensitive adhesive article 100 is observed from the transparent adhesive layer 30 side, and includes an ink existing part 21a in which the ink exists and the transparent adhesive layer 30 contacts the ink and an ink non-existing part 21b in which the ink does not exist and the transparent adhesive layer 30 contacts the base material layer 10. A maximum diameter of an inscribed circle in the ink existing part 21a in the pattern formation area 21 is 500 μm or smaller, and an ink area ratio defined by an occupancy ratio of the ink existing part 21 based on an area of the pattern formation area 21 is 80% or less.SELECTED DRAWING: Figure 1 【課題】開封時の剥離及び開封後の擦過による記載情報の損傷が低減された感圧接着物品を提供すること。【解決手段】基材層１０、印刷層２０、及び透明接着剤層３０をこの順に有する感圧接着物品１００であって、印刷層２０は、インクジェット用インキから構成されるパターン形成領域２１を有し、パターン形成領域２１は、感圧接着物品１００を透明接着剤層３０の側から観察したときに基材層１０の地の部分２２との対比によって認識可能なパターンを形成しており、インキが存在して透明接着剤層３０がインキと接触するインキ存在部２１ａと、インキが存在せずに透明接着剤層３０が基材層１０と接触するインキ不在部２１ｂとを有し、パターン形成領域２１のインキ存在部２１ａにおける内接円の最大直径が５００μｍ以下であり、かつインキ存在部２１ａがパターン形成領域２１の面積に占める割合として定義されるインキ面積率が８０％未満である、感圧接着物品。【選択図】図１
