Abstract: Crosslinkable coating agents based on an organic dispersion (I) of a crosslinkable copolymer (A) which dispersion is stable without an emulsifier and a diisocyanate or polyisocyanate (II). The organic dispersion (I) of the copolymer (A) is prepared by the copolymerization of: A. POLYMERIZABLE COMPOUNDS CONTAINING HYDROXYL GROUPS, WITH B. OTHER COMONOMERS IN C. AN ORGANIC LIQUID IN WHICH THE COPOLYMER (A) formed is not soluble, and in the presence of (B) a copolymer of comonomers from groups (a) and (b) and which is soluble in the organic liquid (c).
