The present invention relates to an aqueous composition comprising anionic organic polymeric particles and colloidal anionic silica-based particles. The anionic organic polymeric particles are obtainable by polymerising one or more ethylenically unsaturated monomers together with one or more polyfunctional branching agents and/or polyfunctional crosslinking agents. The anionic organic polymeric particles and the colloidal anionic silica-based particles in the aqueous composition are present in an amount of at least 0.01% by weight based on the total weight of the aqueous composition. The present invention further relates to a method for the preparation of the aqueous composition, uses of the aqueous composition and a process for the production or paper, in which the aqueous composition is added to a cellulosic suspension.

L'invention concerne une composition aqueuse composée de particules polymériques organiques anioniques et de particules à base de silice anioniques organiques colloïdales. On peut obtenir les particules polymériques organiques anioniques en polymérisant un ou plusieurs monomère(s) éthyléniquement insaturé(s) par un ou plusieurs agent(s) de ramification polyfonctionnels et/ou des agents de réticulation polyfonctionnels. Les particules polymériques organiques et les particules à base de silice anioniques organiques colloïdales de la composition aqueuse sont présentes en quantité au moins égale à 0,01 % par poids par rapport au poids total de la composition aqueuse. La présente invention concerne également un procédé de préparation de la composition aqueuse, des utilisations de ladite composition aqueuse et un procédé de production de papier, selon lequel la composition aqueuse est ajoutée à la suspension cellulosique.
