    • The present invention relates to an aqueous silica-containing composition comprising an anionic organic polymer having at least one aromatic group and anionic silica-based particles. The aqueous silica-containing composition contains the anionic organic polymer having at least one aromatic group and the anionic silica-based particles in an amount of at least 0.01% by weight of the total weight of the aqueous silica-containing composition. The aqueous silica-containing composition contains substantially no cellulose-reactive sizing agent and the anionic organic polymer having at least one aromatic group is not an anionic naphthalene sulphonate formaldehyde condensate. The invention further relates to methods for the preparation of the aqueous silica-containing composition and the use of the aqueous silica-composition as a drainage and retention aid in a process for the production of paper. The invention also relates to a process for the production of paper from an aqueous suspension containing cellulosic fibres, and optionally filler, in which the aqueous silica-containing composition and at least one charged organic polymer are added to the cellulosic suspension.

    • Compositions for enhancing the strength and humidity resistance of lignocellulosic fibrous materials such as paper. The compositions are comprised of at least one lignin derivative and a solvent system whereby the solvent system is comprised of water and at least one organic solvent. Suitable lignin derivatives include but are not limited to lignosulfonate, lignosulfonate/kraft lignin, lignosulfonate/organosolv, and mixtures thereof. Sugar may be optionally added to further enhance the strength and humidity resistance of lignocellulosic fibrous materials. Suitable sugars include but are not limited to sucrose, fructose, glucose, ribose, mannose maltose, glucose amine, and mixtures thereof. Other optional strength enhancing materials including but not limited to starch, carboxymethyl cellulose, and mixtures thereof may also be added if desired to provide additional strength and humidity resistance. The strength and humidity resistance of lignocellulosic fibrous materials treated with the compositions of this invention may be further enhanced by the optional application of thermal energy, radiant energy or combinations thereof. The invention also relates to a method of enhancing the strength and humidity resistance of lignocellulosic fibrous materials.
