摘要

process for producing filler-containing papers and filler-containing paper products, and use of aqueous suspensions of polymer-pigment hybrids. process for producing filler-containing papers and filler-containing paper products by adding an aqueous suspension of at least one finely divided polymer-pigment hybrid to a paper stock and draining the sheet-forming paper stock, the polymer-hybrid pigment being obtainable by grinding an aqueous suspension of at least one inorganic pigment in the presence of at least one binder and, if appropriate, drying the aqueous suspension thus obtained and redispersing the water-dried polymer-pigment hybrid, and the use of the hybrids. polymer-pigment thus obtainable as filler for the production of filler-containing paper or filler-containing paper products.
