Filled paper is made by adding a cationising amount of cationic polymer to precipitated calcium carbonate or other filler either as a slurry or in a thick stock component, producing a thin stock containing the cationised filler and then treating the thin stock with a formaldehyde resin and polyethylene oxide as a retention system prior to drainage and drying.

Préparation de papier chargé, consistant à ajouter une quantité cationisée d'un polymère cationique à du carbonate de calcium précipité ou à une autre charge, soit sous forme de suspension épaisse, soit dans un constituant de pâte épaisse, pour former une pâte légère renfermant la charge cationisée, puis à traiter cette pâte avec une résine de formaldéhyde et un poly(oxyde d'éthylène), comme système de rétention, avant l'égouttage et le séchage.
