CA 2245507

A dispersed rosin sizing composition comprising rosin stabilized by a cationic colloidal coacervate dispersing agent, the coacervate dispersing agent comprising an anionic component and a cationic component, the anionic and cationic components being present in a proportion such that the sizing composition has a zeta potential of at least about 20 millivolts. Methods of making and using the stable rosin sizing composition are also disclosed, as is sized paper made using the sizing composition.

Composition d'encollage dispersée à base de colophane comprenant de la colophane stabilisée par un agent de dispersion coacervé, colloïdal, cationique, qui renferme un composant anionique et un composant cationique, ces composants étant présents en une proportion telle que la composition d'encollage possède un potentiel zêta d'au moins environ 20 millivolts. L'invention se rapporte également à des procédés de fabrication et d'utilisation de la composition d'encollage stable à base de colophane et au papier collé obtenu à partir de cette composition.
