Abstract

The present invention relates to a process for producing paper which comprises: (i) providing an aqueous suspension comprising cellulosic fibres, (ii) adding to the suspension after all points of high shear: a first polymer being a cationic polymer having a charge density above 2.5 meq/g; a second polymer; and a third polymer being an organic or inorganic anionic polymer;
and (iii) dewatering the obtained suspension to form paper.
