摘要： @ A sheet material, generally a wallcovering, is adhered to a substrate, generally a wall or ceiling, by an adhesive which is formed by contacting with water a composition that is free of liquid and ' comprises substantially dry, unswollen polymer particles comprising water-soluble and/or water-swellable polymer particles having particle sizes greater than 20 microns. The polymer may be wholly synthetic or may be a homogeneous blend with a natural polymer. The particles have a surface coating which promotes the dispersibility of the particles in water. The adhesive may be a brush-on adhesive or may be coated on to the sheet material as a prepaste. Prepastes of synthetic polymer particles without the surface coating are also described.

摘要： Pre-pasted wall coverings and other pre-pasted sheet materials are formed by applying a wet coating of an oil-in-water, alkali sensitive polymer and the polymer is converted to a soluble or swellable adhesive form by applying alkali to the wet coating, and the wet coating is dried. The polymer and alkali can be sprayed simultaneously through separate spray orifices but preferably they are applied sequentially, with the polymer preferably being applied by ink jet printing as a discontinuous coating followed by application of alkali.
摘要翻译：通过施加水包油碱敏感聚合物的湿涂层来形成预粘贴的墙面覆盖物和其他预先粘贴的片材，并且通过向湿涂层施加碱来将聚合物转化成可溶或可溶胀的粘合剂形式，并且湿涂层被干燥。聚合物和碱可以通过分开的喷雾孔同时喷雾，但是优选它们顺序施用，其中聚合物优选通过喷墨印刷作为不连续涂层施加，然后施加碱。

摘要： A wallcovering comprises a substrate carrying a water-moistenable coating formed of at least two layers. The layer adjacent to the substrate generally comprises unswollen particles of an anionic polymer that is substantially non-swellable in water and that is swellable in aqueous alkali and the upper layer contains an alkali which on contact with water forms an alkaline solution which swells the anionic polymer and a water soluble cationic polymer. The anionic polymer generally comprises beads of cross-linked copolymers of lower alkyl acrylates and methacrylic acid having a molecular weight of about 5 million. Processes for producing the wallcoverings comprise coating the substrate separately with an aqueous dispersion of the anionic polymer and an aqueous solution containing both the cationic polymer and the alkaline material to give at least two separate layers.
