Pigmented adhesive composition for laminating tissue paper products and methods for producing such compositions

摘要

An adhesive composition for laminating multi-ply absorbent paper products is disclosed. The adhesive composition includes a dry strength binder material, a cationic wet strength resin, and an anionically stabilized titanium dioxide slurry. The cationic wet strength resin is made compatible with the anionically stabilized titanium dioxide slurry by adjusting the pH of the wet strength resin such that it is greater than the isoelectric point of the slurry before the wet strength resin is added to the adhesive composition. Methods of producing the adhesive composition and of laminating absorbent paper products using the adhesive composition are also disclosed.
