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: Core shell particles have a film forming shell layer and monodispersed core particle core contain a coloring agent. Core shell particles (I) whose core and shell materials can form a two phase system are characterized by a film forming shell material; a core that is essentially resistant to the conditions to induce film formation of the shell and does not swell to any great extent. The cores have a monodispersed particle size distribution and the core and shell materials have different refractive indices. The surface of the particle has deposits and/or the shell has inserts of a coloring agent. Independent claims are included for (i) a liquid or paste dispersion (II) comprising a continuous liquid phase containing dispersed particles (I), (ii) a process for the production of (II) by polymerization of core polymer particles with shell polymer monomers or prepolymers and optionally processing aids and additives in an inert liquid reaction medium such that the shell polymer is deposited onto the core particles and the liquid reaction medium contains coloring agent, (iii) a process for the production of decorative and/or protective coatings by application of the dispersion (I), optionally removing the liquid dispersant and/or diluent followed by filming the shell material and crosslinking to orient the core particles and (iv) a process for the production of an effect pigment by application of the dispersion (II) or solid composition onto a poorly adhesive substrate, removal of solvent or diluent, conversion of the shell material of (I) to form a liquid, soft or viscoelastic matrix phase; orientation of the core particles to form domains of a regular structure; hardening of the shell material to fix the structure followed by removal of the hardened film and communition to the desired particle size.

Abstract: The invention relates to a method for producing filled papers and filled paper products by adding an aqueous suspension of at least one finely particulate polymer-pigment hybrid to a paper-making stock and dewatering the paper-making stock while forming sheets. The polymer-pigment hybrid is obtained by grinding an aqueous suspension of at least inorganic pigment in the presence of at least one binder and optionally by drying the aqueous suspension so obtained and redispersing the dried polymer-pigment hybrid in water. The invention also relates to the polymer-pigment hybrids so obtained as fillers for producing filled paper or filled paper products.

Abstract: A coating slip composition which can be applied by the curtain coating method to substrates to be coated, for example base paper or cardboard, is described. The substrate, which may be base paper or cardboard, is coated with one or more free-falling liquid curtains, a binder being added to the coating liquid. The binder is selected from the group comprising styrene/butadiene latex binders, styrene/acrylate latex binders, styrene/butadiene/acrylonitrile latex binders, styrene/maleic anhydride binders and styrene/acrylate/maleic anhydride binders, the binder having a particle size of
