| 1. A method of manufacturing of aqueous suspensions of organic or mineral pigments or fillers, paper coating colors and/or
paper filing or paper surface treating, comprising:
preparing said materials from a composite compound of mineral or organic fillers or pigments, which is comprised of a) a combination
of at least two mineral or organic fillers or pigments, at least one of which has a surface with at least one hydrophilic
site and the other at least has at least one organophilic site co-structured or co-adsorbed by being blended with b) at least
one binding agent, which, when an acrylate polymer, has a specific viscosity of greater than 0.8, forms the composite compound.
