Abstract
Disclosed is a thermally sensitive imagable article and compositions therefor. The imagable article comprises a coating on a substrate, the coating comprising an amino acid or amide, and a compound capable of generating an acid upon heating. The coating optionally comprises a radiation absorbing compound. When imagewise exposed the coating has the property that exposed regions become relatively insoluble in a developer liquid whereas regions that have not been exposed remain relatively soluble in the developer and dissolve in the developer, leaving the exposed substrate in those regions.
