Abstract: 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.

Abstract: Supersensitization of silver halide emulsions is effected by the addition of a metal chelating agent after chemical sensitization or a combination of phenylmercaptotetrazoles and a metal chelating agent to a spectrally sensitized emulsion. The contrast of the emulsion may also be increased by the addition of this combination of materials after chemical and spectral sensitization.

Abstract translation: 卤化银乳剂的超敏化通过在化学增感之后加入金属螯合剂或将苯基巯基四唑和金属螯合剂与光谱增感乳液组合来实现。 在化学和光谱增感之后，通过添加这种材料组合也可以增加乳液的对比度。
