Abstract

A radiation sensitive device is provided with a discontinuous covering layer to improve vacuum draw down. The covering layer is produced by forming a solution or dispersion of the layer-forming material in a liquid hydrocarbon. Drops of the solution or dispersion are then sprayed onto the radiation sensitive device to form the discontinuous covering layer.
