Abstract

A process for forming a highly filled, fibrous-reinforced sheet in which the sheet is formed from an aqueous dispersion of solids which include fibers, filler, and binder and cationic flocculating agent by continuously feeding a stream of such aqueous dispersion onto a moving porous support surface, wherein the filler comprises at least about 50 wt.% of the solids portion of the dispersion, the improvement comprising the use in the aqueous dispersion of a filler consisting essentially of calcium carbonate and a cationic polymeric flocculant having a charge-density of at least about 2 equivalents of cationic nitrogen per kilogram of polymer, and a highly-filled calcium carbonate-containing sheet, and the use of carbon black to impart opacity to paper or sheet that has a white appearance.
