Addition products, radiation-curable surface coating compositions based on the addition products and their use for woodcoating and papercoating

摘要

The present invention relates to addition products ofP P A) oligomers having at least two acrylic ester and/or methacrylic ester groups per molecule andPPB) diamines having a primary and a tertiary amino group,PPthe 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.PPThe invention also relates to processes for the preparation of the addition products, to radiation-curable surface coating compositions based on the addition products and to the use of the surface coating compositions for woodcoating and papercoating.
