Abstract
This disclosure involves a novel process for instantaneous electron-beam curing of very thin low viscosity, solventless coatings upon rough, irregular or textured surfaces of a substrate, such as paper or the like, that, through rather critical timing and energy adjustment procedures, causes the coating firmly to adhere to the surface before the coating can conform to the roughness or texture contour, and thereby providing a solidified very smooth outer surface for the substrate that is particularly useful for metalization and other finished layerings.
