Fluorine-containing compositions for treating substrates to render them oil-, water- and soll-repellant, comprising a fluorine-containing acrylic copolymer and a fluorine-free poly(meth)acrylate.

Substrates which have been provided with an oil-, water- and

Substrates which have been provided with an oil-, water- and soil-repellant treatment from the group consisting of naturally occurring and synthetic textiles and their mixtures, leather, mineral substances, thermoplastic and thermosetting polymers and paper, comprise fluorine-containing compositions which comprise two components A and B. Component A is a fluorine-containing acrylic copolymer with the following comonomers: a) (meth)acrylates containing perfluoroalkyl groups

The invention relates to a blocked polyisocyanate having an NCO functionality of from 2.2 to 4.5 and an average molecular weight of 800 to 25,000 and containing (1) blocked isocyanate groups corresponding to an NCO content of 5 to 20 wt. % calculated as free NCO, relative to unblocked polyisocyanate, (2) 1 to 75 meq of ionic groups per 100 g of blocked polyisocyanate, and (3) 3 to 40 wt. % of polyalkylene oxide units relative to the blocked polyisocyanate prepared by the reaction of

Polyamide-containing fibre materials can be given an anti-stain finish by treating them with a sulpho-containing aromatic formaldehyde condensation product in combination with polyacrylic acid, the treatment with the two components being carried out in any desired order or simultaneously.

Anti-stain finishing of polyamide-containing fibre materials,

The invention relates to reaction products prepared from

The present invention relates to the preparation of coated textile fabrics using an aqueous binder dispersion containing

Process for coating textiles

Finishers for texthes, leather, paper and mineral substrates consisting of fluorine-containing copolymers and aqueous dispersions prepared therefrom are characterized by the following percentages by weight of the comonomers, relative to the total weight of the copolymers:

Fluorine-containing copolymers and aqueous dispersions prepared therefrom

Textiles can be finished in a wash- and cleaning-resistant manner by impregnation if aqueous dispersions are employed for this purpose which contain reactive copolymers and/or cocondensates having perfluoroalkyl groups and water-dispersible polyisocyanate mixtures whose NCO groups are not blocked.

Composition and process for the finishing of textiles

The aromatic formaldehyde condensation products, which are substantially colorless and water-soluble and contain sulphonate and/or carboxylate groups, are obtainable by adding agents which have a reducing action during and/or after the condensation reaction, and are suitable for the treatment of textiles and leather.

Aromatic condensation products

Finishing agents for textiles, leather, paper and mineral substrates of the type mentioned in the title and the aqueous dispersions prepared therefrom are characterized by the following percentages by weight of the comonomers, relative to the total weight of the copolymers:

Fluorine containing copolymers and aqueous dispersions prepared therefrom

The present invention relates to water-dispersible polyetherester-modified polyurethane ionomers containing 10 to 100 milliequivalents of ionic, preferably cationic, groups per 100 g of ionomer; 2 to 40% by weight of polyetherester groups; and 1 to 35% by weight of ethylene oxide units, in which the percentages are based on the weight of the polyetherester-modified polyurethane ionomer. The present invention also relates to a process for the preparation of these polyetherester-modified polyurethane ionomers and to aqueous compositions containing these polyetherester-modified polyurethane ionomers and polymers containing perfluoralkyl groups.
