摘要： Process for the formation of 1-H-pyrazolo[3,2-C]-1,2-4-triazoles useful in photographic chemistry as magenta couplers. The products have chlorine or bromine available at the coupling site, and the following formula: ##STR1## wherein X is chlorine or bromine, n is 0 to 6, and each R is an organic group as defined herein. The compounds are made from a hydrazone by reacting it ##STR2## with chlorine or bromine and a base. When the base is a substance such as sodium acetate, the reaction is conducted in one step. When the base is an amine such as a tertiary amine, reaction of (I) is conducted sequentially. Thus, in this second embodiment, (I) is first reacted with chlorine or bromine, and the reaction product thereby produced is treated with the tertiary amine.

摘要： Photographic reagents can be released, under alkaline conditions, from certain photographic reagent releasing compounds by means of oxidized 3-pyrazolidone developing agents. Particularly useful are acyclic and cyclic compounds in which the photographic reagent is linked, through a hetero atom, to a carbon atom which is adjacent to or in conjugation with a carbonyl group or an imino group. Upon reaction, under alkaline conditions, with an oxidized 3-pyrazolidone developing agent, the bond between the hetero atom and the carbon atom is cleaved. Photographic assemblages containing photographic reagent releasing compounds and processes of releasing photographic reagents in photographic elements and assemblages are described.
