新型萘酚类二当量青成色剂的全合成及照相性能研究

Total Synthesis of Novel 2-Equivalent Naphthol Type Cyan Coupler and Studies on Photographic Properties

本文报导了一种新型萘酚类二当量青成色剂１－羟基－４－（２－甲磺酰基乙氧基）－Ｎ－正十六烷基－２－萘甲酰胺的合成路线及合成方法．从１，４－二羟基－２－萘甲酸经过五步反应合成了该青成色剂及有关中间产物．通过ＩＲ、ＵＶ、１ＨＮＭＲ、１３ＣＮＭＲ、ＭＳ、元素分析等方法测定了该青成色剂的结构．并且还对该青成色剂的基本照相性能（如感光度、灰雾、反差、涂布银量等）及其与彩色显影剂的偶合反应机理进行了比较研究．

The synthetic route and method of a novel 2-equivalent naphthol type cyan coupler is described. 1- Hydroxy - 4 - (2- methylsulfonylethoxy) - N - hexadecyl - 2- naphthamide and some of its corresponding intermediate products were prepared from 1, 4-dihydroxy-2-naphthoic acid via five steps. The structure of the cyan coupler was determined by methods of IR ; UV; HNMR; C NMR ; MS and elemental analysis. And some basic photographic properties (such as S; Do; γand Ag°) of the cyan coupler and the mechanism of the coupling reaction with color developer were compared and studied.
