Abstract

The present invention relates to linear, film-forming diisocyanate polyaddition products soluble in lacquer solvents which contain 10 to 69 wt. % of structural units of the formula: ##STR1## and processes for producing such diisocyanate polyaddition products. The polymer produced may be polyureas, polyhydrazocarbonamide, a polyurethane polyurea, polyurethane polyhydrazocarbonamides, polyurea polyhydrazocarbonamides or polyurethane polyurea polyhydrazocarbonamides. These diisocyanate polyaddition products are useful for the production of surface coatings, lacquer coatings and impregnations.
