Abstract: An inorganic pigment which is treated with at least one non-reactive polysiloxane of the general Formula I In general Formula I, R1 to R8 are the same or different and are selected from CmH2m+1, wherein m is ?10, and fluorinated derivatives thereof wherein at least one hydrogen atom is replaced by fluorine, C6H5, and (EO)x(PO)y and copolymers thereof, wherein EO is an oxyethylene unit, PO is an oxypropylene unit, x and y are the same or different, and x+y is in the range of 1 to 50. The at least one non-reactive polysiloxane has a viscosity in the range of 50-3000 mm2×s?1 at 25° C. The inorganic pigment treated with the at least one non-reactive polysiloxane of general Formula I has a residual moisture content of less than 1 wt-%.
