摘要
合成了以2 氨基 5 巯基 1,3,4 噻二唑为吸附基团,4,4 二甲基 1 苯基 3 吡唑啉酮为增强基团的新型功能性显影促进剂,其结构经IR、1H NMR、MS和元素分析等得到确证.由于其结构的独特性,可望在促进显影的同时而不导致灰雾增大.可将其直接用来促进显影,或者将其与卤代成色剂母体反应得到DAR成色剂后再用于促进显影.
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.
