Described is a process for the preparation of a N-[2-(2-pyridinyl)ethyl]carboxamide derivative of general formula (I) or a salt thereof. 

Process for the preparation of a 2-pyridylethylcarboxamide derivative

The present invention relates to an aqueous polyurethane dispersion obtainable by the reaction of at least: (A) one polyisocyanate with two or more isocyanate groups, (B) one polyester component comprising (B1) a polyesterpolyol with a mean molecular weight of 300 to 900 g/Mol, having structural units derived from terephthalic acid, (C) one ionic group introducing compound with at least one sulphonate and/or carboxylate group and at least one isocyanate reactive group, (D) one diol with a mean molecular weight of 62 to 400 g/Mol, (E) one polyol with a mean molecular weight of 62 to 400 g/Mol, having three or more hydroxyl groups, (F) one amino functional and/or aminohydroxyl functional compound, its use to coat a substrate and a coating obtained by using the dispersion.

Aqueous polyurethane dispersion comprising a terephthalic acid polyester

The invention relates to a cationically hydrophilized polyurethaneurea characterized in that it is synthesized from The invention further relates to an aqueous dispersion comprising the polyurethaneurea and to a coating composition comprising the polyurethaneurea or the corresponding aqueous dispersion. Further subjects of the invention are a method for coating substrates using the coating composition of the invention, and the coated substrate obtainable in such a method.

Polyurethaneureas for wood coatings

The invention is directed to a one-component (1K) coating system comprising an aqueous polyacrylate polymer dispersion and one or more compounds of elements of sub-groups 5 and/or 6 of the periodic table in which the particular element has an oxidation state of at least +4.

Aqueous acrylic coating system and method for improving the appearance of grained wood surfaces

The present invention relates to biomedical foam articles for the wound sector which are formed by spraying a polymeric dispersion onto a wound. The polymeric dispersion being sprayed onto a wound surface forms a three-dimensional body which conforms to the spatial shape of the wound and which, as well as covering the wound surface, ensures a complete and accurately fitted packing of the wound in the depth dimension as well as the other dimensions. The biomedical foam articles of the present invention are particularly useful for treating chronic wounds.
