Coating compositions for glass substrates

A new process for the production of high purity (cyclo)aliphatic diurethanes from (cyclo)aliphatic diamines, alcohols and urea in a multistep reaction in which (1) urea is reacted with alcohol with elimination of ammonia, (2) diamine is then introduced into the reaction mixture, optionally in the form of a solution in alcohol, and reacted with continuous release of ammonia and (3) the reaction mixture is freed from volatile components by distillation. The diurethanes produced by this process are useful as starting materials for the production of the corresponding diisocyanates by thermal urethane cleavage.

Process for the production of diurethanes and their use for the

The invention relates to a method for coating textiles and/or leather with an aqueous dispersion comprising (A) a mixture of (i) a urethane-containing blocked NCO prepolymer having a number average molecular weight of 2000 to 10,000, a content of blocked isocyanate groups (calculated as NCO) of 0.5 to 5 wt. %, an ethoxy group content of 2 to 50 wt. %, an ionic group content of 5 to 30 meq per 100 g of the prepolymer, and
