WALLPAPER
PROBLEM TO BE SOLVED: To provide wallpaper in which paper is used as a base material, and which is composed of a foamed resin layer that is foamed and a patterned printing layer laminated on the base material, and which does not easily expand or shrink due to absorption of water.SOLUTION: Wallpaper comprises a paper base material 1, a foamed resin layer 2, a pattern printed layer 3 and a surface protective layer 4 which are laminated in this order, in which mixed paper containing hydrophobic synthetic fibers and natural pulp is used as the paper base material 1, and the surface protective layer 4 contains acrylic resin as a main component. Since synthetic fibers are poor in stretchability due to water absorption, even when an aqueous adhesive permeates the paper base material, it prevents its elongation. Since the surface protective layer 4 contains acrylic resin as a main component, expansion and contraction due to water absorption is small.SELECTED DRAWING: Figure 1
【課題】紙を基材とし、この基材上に発泡した発泡樹脂層と絵柄印刷層とを積層した壁紙において、吸水による伸縮が生じ難い壁紙を提供すること。【解決手段】紙基材１、発泡樹脂層２、絵柄印刷層３及び表面保護層４がこの順に積層され、紙基材１として疎水性の合成繊維と天然パルプとを含む混抄紙を使用し、表面保護層４がアクリル樹脂を主成分とする壁紙。合成繊維は吸水による伸縮性に乏しいため、水性接着剤が紙基材に浸透した場合にも、その伸張を防ぐ。表面保護層４がアクリル樹脂を主成分とするため、吸水による伸縮が少ない。【選択図】図１
