- W2387887957 abstract "DAR couplers(Development Accelerator Releasing Coupler) are contained in the light-sensitive silver halide photographic material.They are represented by the general formula C_p-L-A in which C_p represents a coupler residue.A represents a development accelerating functional group and L represents a divalent linking group.In this paper,three DAR yellow couplers are synthesized:C_p is α-pivalyl-2-chlor-5-acetanilide;L is 2,5-dimercapto-1,3,4-thiociazol;A are 1-formyl-2-(4-aminophenyl)hydrazide,1-acetyl1-2-(4-aminophenyl)hydrazide and 1-trifluoroacety1-2-(4-aminophenyl)hydrazide.The structures of couplers are identified by IR,~1HNMR,and MS." @default.
