SUBSTANCE: composition comprises: a) a filler, b) a cationic inorganic compound - polyaluminumchloride, c) a cationic organic compound, and d) anionic polysaccharide. The filler is present in an amount of at least about 1% by weight, based on the total weight of the composition. Anionic polysaccharide is present in an amount from about 1 to about 100 kg/ton based on the weight of the filler. The composition is substantially free of fibers. Filler composition of the version contains the components a), b), c) and d), as defined above. The only difference is that the component c) is a cationic polyamine condensation polymer, and the component d) has a degree of substitution of stoichiometrically excess anionic groups of up to about 0.65. At that each of b) and c) components present in an amount from about 0 to about 30 kg/ton based on the weight of the filler. At that the composition comprises at least one of b) and c) components. Methods of obtaining compositions of filler comprise mixing a), b), c) and d), as defined above. The invention also relates to a filler composition, which is obtained by this method, an application of the filler composition as an additive to an aqueous suspension of cellulose in the production process of paper and to manufacturing paper comprising adding a filler composition to an aqueous suspension of cellulose. The invention also relates to a paper obtained with this method, and paper comprising the filler composition.

EFFECT: improvement of composition.
