1. A method for producing matt surfaces comprising:
(1) applying a radiation-curable coating agent to a substrate; (2) irradiating the radiation-curable coating from step (1) with UV light having a wavelength from ≧200 nm to ≦420 nm in a radiation dose from 25 to 120 mJ/cm2, (3) irradiating the coating obtained from step (2) with UV light having a wavelength from ≧120 nm to ≦230 nm, (4) finish-curing the coating obtainable from step (3) by actinic radiation. |
