Abstract
Microvoid-containing sheet material of the type which displays visible indicia when a liquid applied to the surface fills the microvoids. The improvement lies in making the liquid-receiving surface from particles held in pseudo-sintered juxtaposition by a thermoset binder, thereby rendering the structure resistant to inadvertent marking when it is subjected to heat, pressure, or both.
