Abstract: A novel functional photographic developement accelerator was synthesized in this paper.It has a linking group which is 2-amino-5-mercapto-1,3,4-thiociazole and an accelerator group which is 4,4-dimethyl-1-phenyl-3-pyrazolidinone.The structure of the functional photographic development accelerator was identified by IR,~1H-NMR,MS,and elemental analysis.It can be used to accelerate development without unduly increasing fog because of it’s unique structure.It can be used directly or was synthesized with Cp-X to obtain DAR couplers to accelerate development.

Key words: development accelerator, synthesis, DAR coupler
