  • Patent number: 9701843
    Abstract: Disclosed are compositions of fillers coated with adhesion promoting material alone, or also coated with an additive, processes for producing the coated fillers, the fillers obtained from those processes, and methods of using the coated fillers. The filler particle(s) are surface-treated with a component which assists in the adhesion/adherance of an additive to the filler particles, resulting in the desired additive-coated fillers. The filler, adhesion promoting material and additive can be mixed in slurry and dried, and the resulting filler particles are directly useful in many applications, such as paper coatings, plastic compositions (both foamed and non-foamed), inks, paints, cosmetics, textiles and the like, wherever such fillers now find application. Preferably, the additive is a colorant.
