Abstract

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.
