Abstract: A method of producing a wall or ceiling covering that is dry-stripable from the wall, is flexible and has good opacity, and will fully retain an embossed pattern even when the sheet is soaked with a water based adhesive. A sheet is provided containing 10 to 90% by weight of cellulose pulp fibres and 10 to 90% by weight of discontinuous fibres of two different synthetic thermoplastic polymeric materials. Staple fibres may also be added. The sheet is then heated to a temperature intermediate the temperature of plasticity of the two different thermoplastic materials so that the fibres of one of the thermoplastic materials are rendered plastic and fused together, the other thermoplastic material retaining its fibre structure.

Abstract: Production of a wall or ceiling covering comprising an embossed laminate of a first printable embossable ply, and a second supporting ply. The first ply consists of a paper sheet containing 60-100% by weight of cellulose wood pulp fibers and 0-40% discontinuous fibers of a synthetic thermo-plastic polymeric material. The second ply consists of a sheet of 10-60% cellulosic wood pulp fibers, and 40-90% of thermoplastic fibers (either the same as or different than those in the first ply). A fused three dimensional network is formed by heating the laminate to a temperature at which the thermoplastic fibers are rendered plastic.

Abstract: A decorative sheet material having a decorative surface and a working surface, the working surface being provided with a coating of a water-activatable adhesive, in which the improvement is disposing a coating of a dry powdered deliquescent material on the adhesive coating.
