    摘要: A process for producing a polyphenol diester comprises esterifying a polyphenol compound and a naphthoquinone-1,2-diazidesulfonyl halide in the presence of for example monomethyldicyclohexylamine, and a positive photosensitive composition contains the resultant ester. According to this process, a diester of any polyphenol compound can be obtained with ease in a good yield, and a composition using the diester can achieve a high definition and a satisfactory exposure margin.
