To provide a foamed wallpaper that surface hardness is high, has scratch resistance and staining resistance, can be manufactured with normal facilities, has high productivity, and can be manufactured stably while checking the quality.SOLUTION: A foamed wallpaper has at least a surface protective layer (4), an ink layer (3), and a foaming resin layer (2) sequentially on a paper backing (1). The foaming resin layer is foamed by a microcapsule foaming agent or a chemical foaming agent and made from aqueous ethylene-vinyl acetate copolymer emulsion provided from a combination of ethylene group and a monomer having hydroxyl group and carboxy group. The surface protective layer is made from emulsion that the main resin component is acrylic acid ester copolymer.SELECTED DRAWING: Figure 1
【課題】表面硬度が高く、耐傷性や耐汚染性があって、かつ、通常の汎用設備で生産でき、生産性の高く、品質を確認しながら安定して製造可能な化粧シートを得る。【解決手段】紙質基材（１）上に、少なくとも表面保護層（４）、インキ層（３）、発泡樹脂層（２）、を順に有する壁紙であって、発泡樹脂層がマイクロカプセル発泡剤、あるいは化学発泡剤により発泡し、エチレン基と、水酸基、カルボキシ基を有するモノマーとの組み合わせから得られる水性のエチレン酢酸ビニル共重合体エマルジョンから製造される発泡樹脂層、表面保護層がアクリル酸エステル系共重合体を主な樹脂成分としたエマルジョンから製造される表面保護層、からなることを特徴とする発泡壁紙。【選択図】図１
