Method for improving the holdout of printing inks, lacquers and coating compositions on sheetlike structures made of fibers and for improving the deinking of the fibers composition for implementing the method, and sheetlike structures produced therewith

摘要

The process according to the invention for improving the holdout of printing inks, lacquers and coating compositions containing organic solvents on fabrics made of fibers, in particular on paper and for improving the de-inking of the fibers, consists in that an organophilic complex of (a) a water-insoluble hydrated cation-exchangeable film-forming smectic layered silicate with an ion exchange capacity of at least 50 meq / 100 g and (b) an attached organic residue derived from an onium compound into the fiber mass or into the surface of the fiber structure, the organophilic complex by reaction with the organic solvent Barrier forms.
