Abstract
Foamed, opacifying elements are prepared using a foamable aqueous composition containing porous particles and an opacifying colorant. This composition is aerated, disposed onto a substrate, and dried. The dry foamed composition is densified, and cured in either order. At some point after the drying feature, a functional composition is disposed onto either the dry foamed composition or the opacifying layer, and dried. This functional composition has either or both of: (i) inorganic or organic spacer particles having a mode particle size of 1 to 100 μm, and which inorganic or organic spacer particles resist melt flow at a pressure of up to and including 100 psi (689.5 kPa) and a temperature of up to and including 220° C.; and (iii) a tinting material comprising a pigment, dye, or a combination thereof. The (i) inorganic or organic spacer particles and the (iii) tinting material are different materials.
