ABSTRACT:
A radiation-sensitive, imageable article comprises in sequence a substrate, a vapor-deposited colorant layer capable of providing a reflection optical density of at least 0.6 to a 10 nm band of the electromagnetic spectrum between 280 and 900 nm, a vapor-deposited metal or metalloid layer of uniform composition, and a photosensitive resist layer which is non-integral with said colorant layer, the ratio of the thickness of said colorant layer to said metal or metalloid layer being at least 7:1.
