<p><P>PROBLEM TO BE SOLVED: To provide a foam wallpaper which can be obtained by forming a foaming agent-containing resin layer which contains a thermal decomposition foaming agent and also forming a foam resin layer by foaming the foaming agent-containing resin layer and in which the discoloration of the foam resin layer with elapse of time after foaming is suppressed. <P>SOLUTION: In this foam wallpaper having at least a foam resin layer on a substrate of paper quality, (1) the foam resin layer is formed by foaming the foaming agent-containing resin layer which contains the thermal decomposition foaming agent, (2) the foaming agent-containing resin layer is formed by forming, in a film, a resin composition which contains pentaerythritol, and (3) a non-foam resin layer A comprising an ethylene polymer or copolymer which does not have methacrylic acid as a copolymer component is formed further on the front surface of the foam resin layer. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
