Abstract
A foamed, opacifying element has a porous substrate composed of woven yarn strands composed of a thermoplastic polymer-coated multifilament core. It has a dry foamed composition on an opposing surface of the substrate, which includes: (a) 0.1-40 weight % of porous particles; (b) 10-80 weight %; (c) 0.2-50 weight % of one or more additives selected from the group consisting of dispersants, plasticizers, flame retardants, optical brighteners, thickeners, biocides, fungicides, tinting colorants, metal flakes, and inert inorganic or organic fillers; (d) less than 5 weight % of water; and (e) at least 0.002 weight % of an opacifying colorant different from all of the one or more additives of (c), which opacifying colorant absorbs electromagnetic radiation having a wavelength of 380-800 nm. The elements have a light-blocking value (LBV) of at least 4 and can have a bending stiffness that is greater than 0.15 milliNewtons-meter.
