The present invention relates to a filler composition comprising
a) a filler,
b) a cationic organic compound which is a cationic organic polymer, and
c) an anionic polysaccharide,
wherein the filler is present in an amount of at least about 1 % by weight, based on the total weight of the composition, the cationic organic compound is present in an amount of up to about 30 kg/ton, based on the weight of filler, and the anionic polysaccharide has a degree of substitution of net anionic groups of up to about 0.65. The invention further relates to a method of preparing a filler composition comprising mixing a), b) and c) as defined above. The invention further relates to a filler composition obtainable by the method, use of a filler composition as an additive to an aqueous cellulosic suspension in a papermaking process, and a process of producing paper comprising adding the filler composition to an aqueous cellulosic suspension. The invention further relates to paper obtainable by the process and paper comprising the filler composition. |
