    • Sulfonyl hydrazides are used as developers in phothothermographic and thermographic elements. The sulfonyl hydrazides have the formula:R.sup.1 --CO--NHNH--SO.sub.2 --R.sup.2wherein R.sup.1 and R.sup.2 may be each independently selected from the group consisting of alkyl and alkenyl groups of up to 20 carbon atoms, preferably alkyl and alkenyl of up to 10 carbon atoms, more preferably alkyl and alkenyl groups of up to 5 carbon atoms; alkoxy groups of up to 20 carbon atoms, preferably of up to 10 carbon atoms, and more preferably of up to 5 carbon atoms; aryl, alkaryl, and aralkyl groups of up to 20 carbon atoms, preferably of up to 10 carbon atoms, and more preferably up to 6 carbon atoms; aryloxy groups of up to 20 carbon atoms, preferably of up to 10 carbon atoms, and more preferably of up to 6 carbon atoms; non-aromatic and aromatic heterocyclic ring groups containing up to 6 ring atoms; alicyclic ring groups containing up to 6 ring carbon atoms; and fused ring and bridging groups comprising up to 14 ring atoms.The photothermographic and thermographic elements the present invention may be used as a photomaks in a process where there is a subsequent exposure of an ultraviolet radiation sensitive imageable medium.
