ABSTRACT:
A radiation sensitive device comprising a substrate carrying a radiation sensitive layer is coated with a discontinuous covering layer which is more light sensitive than the radiation sensitive layer. The covering layer is formed by spraying and assists in improving vacuum drawdown during image-wise exposure of the device without having a deleterious affect on the exposure and development characteristics of the device.
