摘要

PROBLEM TO BE SOLVED: To provide a foam wallpaper having a high foaming ratio made from olefin material.;SOLUTION: A raw fabric 1 for wallpaper includes a foaming agent-containing resin layer 4 laminated on a substrate 2. The foaming agent-containing resin layer 4 contains at least an olefin resin as resin component. At least a part of the resins to form the foaming agent-containing resin layer 4 has a molecular structure having side chains. In the molecular structure having side chains, the number of side chains with a chain length of 20 or more carbon atoms is larger than the number of side chains with a chain length of less than 20 carbon atoms.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
