摘要：
The present invention relates to polyurethanes (A) being obtainable by reaction of (a) 15% to 70% by weight of di- or polyisocyanate comprising on average from 1 to 10 allophanate groups and on average from 1 to 10 C—C double bonds per molecule, and optionally (b) 0% to 60% by weight of further di- or polyisocyanate, with (c) 5% to 50% by weight of compounds having at least two isocyanate-reactive groups, comprising at least one polycarbonate diol with a molecular weight from 500 to 3000 g/mol weight % ages being based on total polyurethane (A), with the proviso that the total is 100%.
