摘要

Addition products, radiation-curable surface coating compositions based on the addition products and their use for woodcoating and papercoating The present invention relates to addition products of A) oligomers having at least two acrylic ester and/or methacrylic ester groups per molecule and B) diamines having a primary and a tertiary amino group, the ratio of primary amino groups of B) to the (meth)acrylic double bonds of A) being 0.01:1 to 0.2:1, preferably 0.03:1 to 0.1:1. The invention also relates to processes for the preparation of the addition products, to radiationcurable surface coating compositions based on the addition products and to the use of the surface coating compositions for woodcoating and papercoating.
