FIELD: polygraphic industry. SUBSTANCE: Pigment, suitable in ink-jet printing paper manufacture, contains porous calcium carbonate crystals having common pore-surrounding framework and specific surface more than 5 and preferably from 10.0 to 100.0 sq.m/g. Weight of pigment constitutes 20 to 80% of the weight of unbroken dense calcium carbonate particle having corresponding outside volume. Pigment is prepared by heating calcium oxalate to temperature superior to 440 C and maintaining this temperature at least 2 h in nitrogen, carbon dioxide, or air atmosphere, during which time calcium oxalate loses crystallization water and decomposes into calcium carbonate and carbon monoxide. Printing cellulose- containing substrate, in particular paper or cardboard with density 30 to 500 g/sq.m (for instance ink-jet printing paper), is coated by calcium carbonate including more that 5% and preferably 20 to 80% of above-described pigment. Coating may further contain particles of calcium sulfate, aluminum silicate, kaolin, aluminum hydroxide, magnesium silicate, talk, titanium dioxide, barium sulfate and/or zinc oxide. EFFECT: increased absorption capacity of paper, prevented blotting of ink during ink-jet printing, and accelerated ink drying. 19 cl, 7 dwg, 2 ex _
