Abstract
The present invention relates to coating compositions based on polyurethane polymers and melamine- and/or urea-formaldehyde resins as cross-linking agents. At least a portion of the chain lengthening agent used to prepare the polyurethane polymers is based on 2,2-bis(hydroxymethyl)propionic acid amide. By using this particular chain lengthening agent, the coating composition can be applied to textile substrates by the direct or reverse coating process and curved at lower temperatures. The present invention additionally relates to the preparation of these coating compositions and to their use as the adhesive coat in preparing coated textile substrates by the direct or reverse coating process.
