| Abstract: | DARCoupler (Development Accelerator Releasing Coupler) which is contained in the lightsensitive silver halide photographic material is represented by the formula CoupLA. wherein Coup represents a coupler residue, L represents the linking group, A represents the accelerator group. In this paper, a colorless DARcompounds is synthesized, Coup group is acetophenonyl, L represents 2,5dimercapto1,3,4thiociazole, A represents 1benzoyl2(4aminophienyl)hydrazine. The results of experiment indicate the silver halide blackwhite CT (Computer Tomography) lightsensitive material containing colorless DARCompound has a light contrast and sensitivity. |
