Abstract: The present invention pertains to aqueous polyurethane-polyurea dispersions which are prepared by the acetone process using methyl acetate instead of ketones and are chain-extended using hydrazine or derivatives thereof, these dispersions having an improved stability towards thermal yellowing and a relatively low residual hydrazine/hydrazine derivative content.
Abstract: The invention relates to a coloured polymer dispersion containing, as main ingredients: (a) a coloured polymer produced by polymerisation of monomer A with monomer B, monomer A being a pigment B which is coated with a polymerisable wax D wherein the polymerisable function is an ethylenically unsaturated group, monomer B being a ethylenically unsaturated compound; (b) at least one non-ionic surface-active additive E based on polyethers and/or polyglycerines; (c) at least one anionic surface-active additive F based on sulfonates, sulfates, phosphonates, phosphates or carboxylates; and (d) water.

Abstract: The present invention provides novel azo dye material based on antipyrine azo structure and metal complexes containing such azo compounds which are suitable for optical recording media. The dyes exert high light-fastnesses properties and excellent recording characteristics. In particular the invention relates to optical layers comprising such dyes, to a method for manufacturing such optical layers and to optical recording media comprising such optical layers.
Abstract: The use is claimed of aminoacetones or salts thereof of the general formulae (I) and (II) in which R1 and R2 are each independently hydrogen, C1-C22-alkyl, C2-C22-alkenyl, phenyl or C5-C8-cycloalkyl, or R1 and R2, together with the nitrogen atom, form a 5-, 6- or 7-membered ring system, X? is anion, for example chloride, bromide, iodide, toluenesulfonate, benzenesulfonate, cumenesulfonate, mesitylsulfonate, sulfate, hydrogensulfate, acetate, fatty acid anion or anion of polycarboxylates, as a bleaching booster for inorganic peroxygen compounds in the pH range from 7 to 9.

Abstract: The invention relates to a method for producing nanoparticles of aluminium spinels. According to said method, a salt of a metal, the oxide of which can form a spinel lattice with aluminium oxide, is added to an aqueous solution of aluminium chlorohydrate, the solution is then dried, and calcinated in less than 30 minutes, and the agglomerated material thus obtained is ground.
Abstract: The present invention relates to a process for producing storage-stable concentrated aqueous dye preparations of anionic dyes, to the dye preparations as such, blends/shadings with further anionic dyes and to their use, especially for printing and dyeing fiber materials.
Abstract: The invention relates to combinations of benzylidene-bis-malonate based lightsstabilizers with specific other additives showing synergistic efficiency during long term light exposure of organic substrates.
Abstract: The present invention relates to the use of a compound of the formula (I) in mass coloration which provides dyed polymers with excellent overall fastness properties.

Abstract: The present invention relates to silicone waxes having plural tertiary or quaternary amino groups, their preparation and their use as softeners in the textile industry. These waxes can be processed into stable aqueous dispersions and lead to products having a pleasant, soft hand.
Abstract: The invention relates to novel azo dyestuffs of formula (I), the use of such compounds and/or mixtures for printing recording materials, especially paper or papery substrates, textile fiber materials, plastic films and plastic transparencies by the inkjet printing process and also to the recording materials printed thereby
Abstract: The present invention relates to a process for the trichromatic dyeing or printing of hydroxy-group-containing or nitrogen-containing organic substrates with dye mixtures and also to such dye mixtures and hydroxy-group-containing or nitrogen-containing organic substrates dyed or printed therewith.
Abstract: An aqueous solution is prepared comprising 5 to 25% by weight of an anionic surfactant, 0.5 to 20% by weight of an amphoteric surfactant, 4 to 6% by weight of a nonionic surfactant and, if necessary, an antiseptic and the aqueous solution is adjusted with an organic acid to pH in the range of 4.5 to 7.0, which is used as an undiluted solution of a hydrophilicity maintaining and promoting agent for a polysilazane-containing coating film. The undiluted solution is diluted with water to from 3 to 15 times and the resulting solution is used as a hydrophilicity promoting agent. While the undiluted solution is diluted with water to from 30 to 70 times and the resulting solution is used as a hydrophilicity maintaining agent. The hydrophilicity promoting agent is applied on an anti-fouling coating film which is formed by applying on a substrate a coating solution comprising polysilazane and, if necessary, silica conversion catalyst, and thereby the coating film is made hydrophilic in an extremely short time.
Abstract: The present invention relates to the use of mono- or polyunsaturated alpha-olefÊnsulphonates as an active substance alone or in combination with further codispersants for removing polyester oligomers from fibres, fabrics or textile-dyeing machines, for preventing deposits or for deweighting polyester fibres.
