WALLPAPER WITH ADHESIVE LAYER
To provide a wallpaper which is less likely to generate distortion and wrinkles due to drying shrinkage during construction, does not require energy for moisture drying, and can be easily aligned, temporarily fixed, removed and replaced.SOLUTION: A wallpaper is obtained by laminating a hot melt adhesive layer made of a hot melt resin on one side of a wallpaper substrate. The wallpaper has a 90-degree peeling force of 5 N/50 mm to 12 N/50 mm as measured according to JIS K 6854-1 after the hot melt adhesive layer of the wallpaper is brought into close contact with a gypsum board and heated at 100°C for 1 minute. When the storage elasticity at T1°C of the hot-melt resin is represented as G1 and the storage elasticity at T2°C of the hot-melt resin is represented as G2, there are a temperature T1°C and a temperature T2°C which satisfy G2/G1≥1000 and T2-T1≤40.SELECTED DRAWING: None
【課題】施工時に乾燥収縮による歪みや皺を発生させにくく、また、水分乾燥のエネルギーを必要とせず、更に、位置あわせ、仮止め、撤去、貼り替えを容易に行うことが可能な壁紙を提供する。【解決手段】壁紙基材の片面にホットメルト樹脂から成るホットメルト接着層が積層され、壁紙の前記ホットメルト接着層を石膏ボードに密着させて１００°Ｃで１分間加熱した後、ＪＩＳ Ｋ ６８５４−１に準拠して測定した９０度剥離力が５Ｎ／５０ｍｍ〜１２Ｎ／５０ｍｍであり、ホットメルト樹脂の温度Ｔ１°Ｃにおける貯蔵弾性率をＧ１とし、温度Ｔ２°Ｃにおける貯蔵弾性率をＧ２としたとき、Ｇ２／Ｇ１≧１０００であり、且つ、Ｔ２−Ｔ１≦４０であることを満たす温度Ｔ１℃および温度Ｔ２℃が存在することを特徴とする壁紙。【選択図】なし
