Black pigmented UV-curable coating materials intended for application on wood veneer and fiberboard were prepared and used to compare different compositions. Reactive oligomer/monomer combinations with high acrylate functionality, a suitable and effective blend of long- and short-wave absorbing photoinitiators, and a careful selection of pigment and pigment concentration were necessary to make possible both opacity and through-cure. In this context, the combination of the black pigment with certain extenders can be helpful.
