Abstract

A process for the production of paper from a suspension of cellulose containing fibres, and optional fillers, which comprises adding an aluminium compound and anionic inorganic particles to the suspension, forming and draining the suspension on a wire, wherein the aluminium compound and anionic inorganic particles are mixed immediately prior to addition to the suspension.
