FIELD: pulp-and-paper industry. ^ SUBSTANCE: coating composition consisting of ink-compatible pigment, water-soluble binder, and cationic fixative is deposited onto one of the sides of based paper and the other side is covered with detwisting coating, after which glossy surface is formed. Coating composition is supplemented by wettability controlling agent based on polydimethylsiloxane resins in amounts 0.4 to 1.6% of the weight of pigment. Water-soluble binder is a mixture of polyvinyl alcohol with polyvinylpyrrolidone at ratio (90-50):(10-50) in amount 40-60% and styreneacrylic latex in amount 15-20% of the weight of pigment. When forming glossy surface, polyethylene oxide-based plasticizer is used in amount 7-15% of the weight of pigment followed by supercalendering at pressure in roll contact zone 20-25°C and temperature 50-90°C. ^ EFFECT: improved manufacturability of process. ^ 5 cl, 1 tbl, 54 ex
