Methylolated and optionally etherified urethanes containing fluoroalkyl ligans with formaldehyde, with or witout subsequent etherification, and are in the form of their solutions or aqueous dispersions suitable for the treatment of textiles and leather.

Methylolated and optionally etherified urethanes containing fluoroalkyl

An agent effective for oleophobizing and hydrophobizing textiles is an aqueous anionic dispersion which comprises water and

Aqueous anionic dispersion

Water-soluble polycoesters, process for their preparation, and their use

The novel urethanes correspond to the formula I below ##STR1## in which a denotes a number from 5 to 17 and b denotes a number from 1 to 7. These urethanes are prepared by reacting the corresponding perfluoroalkylethanol/epichlorohydrin adducts with toluelene diisocyanates. The novel aqueous dispersions are essentially composed of the novel urethanes, cationic or betaine emulsifiers and non-ionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic acid esters and alkanediols or polyalkanediols which can be etherified on one or both sides, in water. The novel urethanes and the novel aqueous dispersions are used to impart an oleophobic and hydrophobic finish to textiles, leather and furs. They are also suitable for the treatment of unpainted timber, for example unpainted furniture.

Modified aminoplast, its preparation and its use

Hydrophobic textile materials exhibit reduced tendency to static charge buildup, significantly improved absorbency and reduced soiling tendency when treated with a water-dispersible polyester having structural units of the formula ##STR1## wherein A is, on statistical average, 80 to 100 mol percent of p-phenylene and 0 to 20 mol percent of divalent moieties of the formula ##STR2## and wherein G is, on statistical average, 30 to 90 mol percent of linear or branched divalent alkane moieties having 3 to 6 carbon atoms which may be interrupted by 1 or 2 oxygen atoms, 10 to 30 mol percent of divalent polyether moieties having an average molecular weight of 1,000 to 3,000, and up to 50 mol percent of ethylene moieties, and R is a straight-chain or branched alkyl or alkenyl having 6 to 8 carbon atoms.

Water-dispersible polyester, its preparation, and its use as a

Improved polyesters soluble or dispersible in water having an apparent average molecular weight of 800 to 5,000 and containing phosphonic ester moieties are useful as levelling auxiliaries for uniform dyeing and are produced by esterifying dibasic acids and dihydric alcohols, either or both of which contain phosphonic acid moieties, phosphonic acid ester moieties or both.

Formulation for brightening synthetic fibers and its preparation and use

Process for dyeing evenly synthetic fiber materials and mixtures thereof with natural fibers, with water-insoluble disperse dyestuffs according to the exhaust method, which comprises adding water-soluble or dispersible linear polyesters that have been obtained by polycondensation of dicarboxylic acids with diols, including sulfo-groups-containing chain links, with an average molecular weight of 800 to 5,000, combined with surface-active oxethylation products, at a blend ratio of 1:0.25 to 1:1.5, as dispersing system with levelling action to the aqueous dyeliquors, besides said dyestuffs and pH-controlling substances.

Water-insoluble monoazo dyes of the formula ##STR1## produced by reacting a diazotized amine of the benzene, naphthalene, diphenyl, diphenylmethane or heterocyclic series which is free from water solubilizing groups with the appropriate 6-hydroxy-2-pyridone and the utility thereof for the dyeing and printing of synthetic fabric materials to yellow to red shades having excellent fastness to light and sublimation.

Water-insoluble monoazo pyridone dye

Dyeing with disperse dyes is made more uniform when there is used as a levelling agent a branched polyester which has an apparent average molecular weight of from about 600 to about 5,000, disperses itself in water, and is essentially an ester-linked combination of hydrocarbyloxy groups and carboxyl-derived acyl groups, the groups being linked together as a branched chain by the ester linkages and relative to the carboxy-derived acyl groups the polyester contains from about 5 to about 50 mol.% of COOH or COOM groups and less than 5 mol.% of SO.sub.3 M groups, wherein M denotes the cation of an alkali metal, the ammonium ion or the cationic radical of an organic amine, the number of branches on an interesterified group being not over three and at least 50 mol.% of the hydrocarbyloxy groups are in diethylene glycol or triethylene glycol groups.
