摘要： Laminated light-blocking decorative articles are prepared by applying an aqueous foamed opacifying composition to a decorative fabric, drying, laminating a non-woven fabric to the resulting dry foamed opacifying layer, and densifying that layer to have a thickness that is at least 20% less than before densifying. This operation can be carried out so that non-woven fabric, decorative fabric, and aqueous foamed opacifying composition are supplied in a single-pass, in-line operation to make any quantity of laminated light-blocking decorative article. The applied aqueous foamed opacifying composition has 35%-70% solids and a foam density of 0.1-0.5 g/cm3. It is composed of (a) porous particles, (b) a binder material, (c) two or more additives comprising at least one foaming surfactant and at least one foam stabilizer, (d) an aqueous medium, and (e) at least 0.0001 weight % of an opacifying colorant that absorbs electromagnetic radiation having a wavelength of 380-800 nm.
