Beschreibung
Zusammenfassung:	FIELD: pulp-and-paper industry. ^ SUBSTANCE: coating composition consisting of ink-compatible pigment, 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 coating is ennobled by means of supercalendering. As pigment, mixture of amorphous silicon dioxide with calcium carbonate or kaolin with outer specific surface 60-85 m2/g at ratio (25-50):(75-50). Binder is a mixture of polyvinyl alcohol with latex selected from class of styreneacrylic copolymers at ratio (20-25%):(7-18%) based on the weight of pigment. Cationic fixative is poly(diallyldimethylammonium chloride), which is directly incorporated into coating composition in amount 5-10%. ^ EFFECT: enabled image quality and paper surface strength control. ^ 3 cl, 1 tbl, 13 ex
