    摘要： This invention relates to PU-coating compositions containing solvent and combinations of crosslinking agents and to a process for producing polyurethane coatings on the principle of heat-activated, one-coat reverse coating by knife-coating the polyurethane coating composition onto a temporary support, drying the layer and laminating the textile substrates using preferably heated pressure rollers, followed by heating at elevated temperatures, the coating compositions used being solvent-containing, 20 to 60% compositions of a polyurethane mixture I containing(A) relatively soft polyurethanes and(B) relatively hard one-component polyurethanes and a crosslinker combination II containing(C) formaldehyde-urea and/or formaldehyde-melamine resins and crosslinking catalysts and(D) aliphatic and/or aromatic polyisocyanates, particularly blocked polyisocyanates,and, optionally, additions of soluble cellulose esters, handle-improving agents, optionally polysiloxanes containing oxyalkylene groups and other standard additives, such as pigments.The heat-active one-coat reverse coatings obtained in this way show surprisingly high dry and wet adhesion values on textile substrates through the mixed crosslinking of the selected polyurethane mixtures and, hence, high article fastness values.

Also provided is a process for preparing these polyisocyanates which comprises reacting about 10 to 30 mol % of the isocyanate groups of an organic polyisocyanate with reaction products which have (i) alcoholic hydroxyl groups and (ii) structural units of the formula, --O--CO--NH--NH--CO--O--, and/or of the formula H.sub.2 N--NH--CO--O--, with the formation of urethane groups and optionally groups corresponding to the formula, --NH--NH--CO--O--, and reacting about 50 to 90 mol % of the isocyanate groups of the organic polyisocyanate with a blocking agent. The reaction products containing alcoholic hydroxyl groups are obtained by reacting 1 mol of hydrazine or of hydrazine hydrate with about 1 to 2 mols of a cyclic carbonate. A final object of the present invention is the use of the new lacquer polyisocyanates as the isocyanate component in thermosetting, two-component polyurethane lacquers.

    摘要： This invention relates to compositions which are crosslinkable by heating to form polyurethane plastics for coating substrates, preferably textile sheet-form materials, in particular by the reverse coating process. For ecological and economic reasons, the coating compositions are free from organic solvent or contain at most 10% by weight of organic solvent and consist essentially of linear and/or branched urethane prepolymers having blocked terminal NCO-groups, aqueous dispersions of urethane polymers, vinyl polymers and/or diene polymers and/or aqueous polymer solutions and aliphatic and/or cycloaliphatic and/or aromatic amines containing at least two primary and/or secondary amino groups as latent crosslinkers. The chain extending or crosslinking reaction takes place at an elevated temperature in a coating tunnel after the coating has been applied to a substrate.
