<p>The subject of the present invention refers to a process 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 substrates 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.</p> |
