Abstract: Two novel DAR couplers were synthesized in this paper,the structures were confirmed by elemental analysis,IR,MS,and 1H-NMR.It was found that D1 could increase sensitivity by 20%,but D2 could not increase sensitivity by the research of it’s photographic properties.

Key words: DAR coupler, synthesis, photographic properties
