摘要: The present invention refers to a process for the production of paper from suspension containing cellulosic fibers, and optionally fillers, comprising adding at least one cationic organic polymer an aqueous silica-containing composition anionic naphthalene sulphonate formaldehyde condensate silica-based particles, having weight ratio particles within range 0.2:1 99:1, in amount 0.01% by weight, based on total composition, with proviso that contains substantially no cellulose-reactive sizing agent. also encompasses method preparation compound.
