Abstract
An imagable article comprises a thermally imagable coating on a substrate, the coating comprising a radiation absorbing compound and a metal compound which is thermally decomposable, to form a metal. The imagable article is imagewise exposed to electromagnetic radiation, which is converted to heat by the radiation absorbing compound. The imaged article is then subjected to a developer, and in regions that have been exposed the thermally decomposable metal compound is decomposed to elemental metal, and regions that have not been exposed dissolve in the developer leaving behind the regions of elemental metal.
