POLYMER-PIGMENT HYBRIDS FOR USE IN PAPERMAKING

摘要

The invention relates to a method for producing filled papers and filled paper products by adding an aqueous suspension of at least one finely particulate polymer-pigment hybrid to a paper-making stock and dewatering the paper-making stock while forming sheets. The polymer-pigment hybrid is obtained by grinding an aqueous suspension of at least inorganic pigment in the presence of at least one binder and optionally by drying the aqueous suspension so obtained and redispersing the dried polymer-pigment hybrid in water. The invention also relates to the polymer-pigment hybrids so obtained as fillers for producing filled paper or filled paper products.
