Abstract

A paper-like or cardboard-like raw material containing inorganic fibres, particulate inorganic additives and organic binders or flocculents is characterized in that (1) the particulate inorganic additives comprise 40-80 wt. % of the dry mass of the raw material (2) the particulate inorganic additives contain (2.1) a basic filler of which at least 20 wt. % has a particle size < 2 mu m and not more than 20 wt. % has a particle size > 20 mu m and < 0.5 mu m, and (2.2) an anionic flocculating active pigment of which at least 50 wt. % has a primary particle size < 2 mu m (3.1) the organic flocculant is a cationic polymeric carbohydrate with a mean molecular weight between 100 000 and 2 000 000 and a degree of substitution between 0.01 and 0.3 and amounts to 0.5 to 6 wt. % of the dry mass of the raw material (3.2) 1000 g of basic filler may bind, with floc formation, not more than 0.1 mmol of cationic carbohydrate and 1000 g of anionic flocculating active pigment binds, with floc formation, at least 0.1 mmol of cationic carbohydrate.
