A process for the production of polyurethane (meth)acrylates, in which a trimer of a (cyclo)aliphatic diisocyanate, 1,6-hexanediisocyanate, a diol component and hydroxy-C2-C4 alkyl (meth)acrylate in the molar ratio 1 : x : x : 3 are reacted without solvent and without subsequent purification operations, wherein x means any desired value from 1 to 6, wherein the diol component is selected from the group consisting of an individual linear aliphatic alpha,omega C2-C12 diol and a combination of two to four (cyclo)aliphatic diols, wherein in the case of diol combination each of the diols makes up at least 10 mol % of the diols of the diol combination and the diol combination consists to at least 80 mol% of at least one linear aliphatic alpha,omega C2-C12 diol. |
