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.
