Light-blocking articles with spacer functional composition

Abstract:

A foamed, opacifying element useful as a light-blocking article has a substrate; an opacifying layer disposed on the substrate, and a functional composition disposed over the opacifying layer. The functional composition comprises: (i) inorganic or organic spacer particles having a mode particle size of at least 1 .mu.m and up to and including 100 .mu.m, 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.degree.
