The present invention provides a formulation for a fibrous non-woven facing material, wherein the formulation comprises a binder, a filler, and an extender. The extender has an median particle size, d.sub.50, which is equal to or less than 3.5 μm, and a non-spherical morphology. The filler has an median particle size, d.sub.50, which is equal to or less than 3.0 μm and wherein the filler has a d.sub.10 equal to or less than 1.0 μm and a d.sub.90 equal to or less than 6.0 μm. The formulation comprises less than 13 wt % titanium dioxide on a dry solids basis. Also provided is a fibrous non-woven facing material comprising the formulation, a process for preparing the fibrous non-woven facing material and a fibrous non-woven facing material obtained by said process.

A wallpaper system may include a sheet of material comprising a top layer comprising a decorative material, a bottom layer to be adhered to a surface, and an intermediate layer located between the top layer and the bottom layer. In some examples the wallpaper system may include an electronic component coupled to the sheet of material and a conductor disposed within the intermediate layer. The conductor may be coupled to the electronic component and may be configured to provide power to the electronic component.

A method for the continuous in-register embossing of a stretchable film is provided where a repeating printed image or a laminate may be formed by way of the stretchable film in an embossing station. The embossing station may include a rotating embossing roll having an embossed image and an associated rotating counter-roll. The printed image length of the film may be stretched longitudinally before the embossing contact with the embossing roll to a length greater than or equal to or smaller than or equal to the embossed image length or the circumference of the embossing roll. The maintenance of register of the embossing may be achieved by way of a relative speed between the circumferential speed of the embossing roll and the web speed of the film in the embossing station.
