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.
