FIELD: textiles, paper.
SUBSTANCE: invention relates to production of paper. The method comprises processing the filler particles with coagulant - a copolymer of acrylamide/ammonium diallyldimethylchloride (AcAm/DADMAC), mixing the filler particles and cellulose fibres, processing the resulting mixture with the hardening additive - glyoxylated copolymer of acrylamide/ammonium diallyldimethylchloride (AcAm/DADMAC) and formation of matte paper. At least 10% of the filler particles are precipitated calcium carbonate and at least 10% of the said filler particles are ground calcium carbonate.
EFFECT: invention enables to manufacture matte paper with a high content of mineral filler without loss of paper strength.
