    Abstract: The invention relates to new radiation-curable composition comprising an aqueous dispersion containing an unsaturated polyurethane with repeating uni ts of tetramethylxylylene diisocyanate as the essential diisocyanate compound. The invention also relates to a process for making these dispersions in the absence of solvents. The product and process can meat severe environmental requirements in terms of absence of solvents, absence of amines and absence of irritating materials. The coatings obtained from the dispersions of the invention have all together a good resistance combined with a good cold flexibility. In particular, the coatings are glossy and exhibit a high adhesion, a good chemical resistance to stain, water and solvent and a good mechanical resistance to scratch and abrasion.
