    摘要: The present invention relates to urethane (meth)acrylates comprising residual isocyanate groups which are obtained from the reaction of:
    a) at least one di- or poly-isocyanate, and
    b) at least one hydroxyl-functional (meth)acrylic acid ester of at least one polymer chain which comprises: at least one (meth)acryloyl group, at least one free hydroxyl group and at least one polymer chain,

    wherein the equivalent ratio of OH groups to NCO groups is 0.05:1 to 0.66:1, a process for preparing thereof and their use in radiation-curable coating composition.
