ABSTRACT OF THE DISCLOSURE The subject of the present invention refers to a pro- cess for the manufacture of so uble organic copolymers, which give non-tacky, water-resistant and elastic films on very diverse substrates or are suitable as binders for pigments, paints and non-wovens, and for the use of these copolymers as a binder component, the sheet-like structures, which can be manufactured from these polymers, having however. properties which are considerably improved in various respects. The binders exhibit a good pigment-binding capacity and also posses good resistance to weathering. These binders are employed mainly as automotive lacquers for final lacquerin or as car touch-up lacquers. The copolymers obtainable according to the invention can be employed together with polyisocyanates in the reactive lacquers in order to produce coatings or coverings on sub- strates of very diverse types, for example porous or non-porous substrates, such as textile non-wovens, leather or plastics. The production of coatings on wood or metals should be singled out in particular. In every case coatings which have a high gloss and a very hard surface and are pore-free, eleastic and resistant to solvents are obtained. Such coatings also exhibit an outstanding resistance to weathering and resistance to yellowing.
