摘要: 本文以α-新戊酰基-2-氯-5-[3-(2,4-二特戊基苯氧基)丁酰胺基]乙酰苯胺为母体,以2,5-二巯基-1,3,4-噻二唑为吸附基团,分别以1-甲酰基-2-(4-氨基)苯肼,1-乙酰基-2-(4-氨基)苯肼和1-三氟乙酰基-2-(4氨基)苯肼为增强基团合成了3种DAR黄成色剂.并通过IR,1HNMR,MS确证了它们的结构.

Abstract: DAR couplers(Development Accelerator Releasing Coupler) are contained in the light-sensitive silver halide photographic material.They are represented by the general formula Cp-L-A in which “Cp” 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:“Cp” 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.

Key words: DAR coupler, DAR yellow coupler, synthesis
