Abstract
The present disclosure is concerned with an improved method of reverse coating textile sheets with storage stable polyurethane top and adhesive coats which are formulated to have improved resistance to deformation under heat and pressure. At least one of the coats is formulated from a diisocyanate, a high molecular weight dihydroxy compound and a mixture of at least one low molecular weight diol with a low molecular weight monoalkanolamine. The coatings are applied in the usual reverse coating manner, i.e. the top coat is applied to a release substrate from solution; dried; the adhesive coat is applied from solution onto the dried top coat; and the textile substrate is laminated to the adhesive coat.
