<p>PURPOSE: An adhesion-resistant, radiation-curable coating system based on high molecular mass is provided to obtain coating with sufficient water resistance and good adhesion resistance after physical dry and radiation hardening. CONSTITUTION: An adhesion-resistant, radiation-curable coating system based on high molecular mass comprises (I) polyurethanes and (II) oligo(meth)acrylate 0-40 weight% which is polymerized by an ethylene-based unsaturated compound in exposure to high energy radiation. The (I) polyurethanes comprises (A) hydroxyl-containing component 40-80 weight%, (B) at least one compound 0.1-20 weight% which is reactive to isocyanate and contains a nonionic group, ionic group or group forming ionic group, (C) hydroxyl- and/or amine-containing component 0.1-30 weight%, (D) hydroxyl-functional compound 0-30 weight%, (E) monoamine, diamine and/or bifunctional amino alcohol 0.1-10 weight%, and (F) at least one polyisocyanate 10-50 weight%.</p> |
