    摘要： A deformable film has a decorative surface featuring a completely matt appearance. For this purpose, the deformable film has a decorative surface provided with at least one coating comprising the following constituents: (a) an aqueous dispersion of a hydroxy-functional prepolymer, obtainable by conversion of at least one of the following components: (i) a component having hydroxyl groups, (ii) a polyester polyol having hydroxyl groups, (iii) a polyisocyanate having isocyanate groups, (iv) a compound having at least two groups reactive toward isocyanate groups and at least one group capable of anion formation, (v) water, where components (i) to (iii) and the ratio of components (i) to (iii) are selected such that an excess of hydroxyl groups is present relative to the isocyanate groups, and (b) nanoparticles having a number-average particle size of 1 to 1000 nm and (c) a crosslinker having at least two groups reactive toward hydroxyl groups.

    摘要： The present invention relates to a method for treating a substance mixture comprising an aromatic amine, wherein the aromatic amine is aniline or 2,4-diaminotoluene, preferably aniline. The substance mixture comprises an aromatic amine and compounds having a higher boiling point than the aromatic amine. The method for treating the substance mixture requires I) separating the first substance mixture by means of distillation in a first distillation unit (110, 1130), to at least partially remove some of the aromatic amine in the process, and to obtain a first bottom product which is removed from the first distillation unit (110, 1130). After removal from the first distillation unit (110, 1130), the bottom product is diluted with a condensed top product from a distillation unit that is different from the first distillation unit and/or with a composition that comprises methanol.

    摘要： A catalytic process for hydrogenating aromatic di- and polyamines with the aid of a selected catalyst system is provided, which comprises a mixture of a first heterogeneous catalyst and a second heterogeneous catalyst and a nitro compound (nitrate and/or nitrite salt). The first and second heterogeneous catalyst each independently comprise a metal selected from the group consisting of Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and/or Pt and the metal selected for the second heterogeneous catalyst is different from the metal selected for the first heterogeneous catalyst. Hydrogenation of aromatic rings having two or more amino groups bound to the aromatic ring produces cycloaliphatic di- and polyamines, which are useful chemical intermediates, e.g., for further reaction with epoxides or isocyanates. The amino groups may also be converted to isocyanates via reaction with phosgene. The resulting cycloaliphatic di- and polyisocyanates may also be used as monomers for making polymers.
