PROCESS FOR THE PREPARATION OF A PIGMENT -FIBRE COMPOSITE

摘要

The invention relates to a process for the preparation of a pigment -cellulosic fibre composite, wherein the pigment comprises an inorganic pigment which comprises local cationic charges, said process comprises contacting an aqueous cellulosic fibre suspension and inorganic pigment particles such that crystals of said pigment are attached to the surface of the fibre, said crystals having a size of at most 5 µm. The produced composite product can be used as a filler pigment or coating pigment in the production of paper.
