Zusammenfassung:	The mfr. of a wall-covering comprises (a) applying a layer of an expandable aq. coating to a substrate layer; and (b) heating the coated substrate to dry the layer of coating and expand the expandable particles. The coating comprises (a) a polymeric binder comprising latex particles of a copolymer having a Tg of -20 0C to +60 0C and Mw of 20,000-500,000; and (b) expandable particles comprising a liq. blowing agent contained within a thermoplastic shell. Also claimed is a wallpaper made by the above process. PREFERRED - The substrate is pref. selected from papers, coated papers, polymer films, nonwoven textiles, woven textiles and/or metal foils. The copolymer is pref. a crosslinkable copolymer which is crosslinked during the heating step.
