Abstract: Cationically surface-modified hydrophilic non-crosslinked homo or co-polymer nanoparticles are claimed, as is also stain-release treatment of textile or non-textile surfaces using aqueous dispersions of the particles. INDEPENDENT CLAMS are included for: (1) cationically-modified hydrophilic non-crosslinked polymer nanoparticles of size 10 nm to 2 microns which are surface-coated with cationic polymers, polyvalent metal ions or cationic surfactants, the crosslinked polymer comprising (by wt.) (a) carboxyl group-containing ethylenically-unsaturated monomers or salts (60-100%); (b) water-insoluble mono- ethylenically-unsaturated monomers (0-40%); (c) sulfonic- and/or phosphonic-acid-containing monomers (0-25%); and (d) water-soluble nonionic monomers (0-30%); (2) aqueous dispersions of such particles, the dispersions being stabilized with anionic, nonionic and/or betaine-type surfactants and/or protective colloids; and (3) stain-releasing treatment of textile or non-textile surfaces using the dispersions.

Abstract: Cationically surface-modified hydrophilic crosslinked polymer nanoparticles are claimed, as is also stain-release treatment of textile or non-textile surfaces using aqueous dispersions of the particles. Independent claims are included for: (1) cationically-modified hydrophilic crosslinked polymer nanoparticles of size 10 nm to 2 microns which are surface-coated with cationic polymers, polyvalent metal ions or cationic surfactants, the crosslinked polymer comprising (by wt.): (a) carboxyl group-containing ethylenically-unsaturated monomers or salts (60-99.9%); (b) water-insoluble mono- ethylenically-unsaturated monomers (0-40%); (c) multi-ethylenically-unsaturated monomer (0.01-30%); (d) sulfonic- and/or phosphonic-acid-containing monomers (0-25%); and (e) water-soluble nonionic monomers (0-30%); (2) aqueous dispersions of such particles, the dispersions being stabilized with anionic, nonionic and/or betaine-type surfactants and/or protective colloids; and (3) stain-releasing treatment of textile or non-textile surfaces using the dispersions.

Abstract: The invention relates to particle-shaped, line-shaped, planiform or three dimensional entities comprising, at least on the surface thereof, a hydrophilically effective amount of at least one polymer containing urethane and/or urea groups in addition to ammonium groups. The ammonium groups are obtained by quaternizing or neutralizing tertiary amino groups, preferably with carbonic acid.
