ABSTRACT:
A topcoat is applied over a coating which has been gelled by actinic light and which is curable by ionizing irradiation. The gelled coating and the topcoat are exposed to ionizing irradiation to cure the gelled coating. It is preferred that the topcoat as applied be curable by ionizing irradiation so that it will also be cured during exposure to ionizing irradiation.
