Abstract
The radiation curable compositions (I) that comprise from 10 to 80 by weight of at least one silicone-modified urethane (meth) acrylate (A), from 0.5 to 60 by weight of at least one (meth) acrylated compound (B) bearing at least 5 (meth) acryloyl groups per molecule, and optionally, from 10 to 60% by weight of at least one compound (C) different from (A) or (B), wherein the weight percentages are on the total weight of the composition (I). These materials can be used for producing coatings, inks and overprint varnishes with excellent anti-stain properties, to their use and preparation. Materials of the invention are compatible with standard radiation curable materials. They allow to obtain excellent anti-stain properties for high gloss coatings as well as for matte coatings (II) with a gloss level at 60° of at most 15, even at most 10.
