摘要: 本文研究了苯酚类(A),双酚类(B),对苯二酚类(C),色满类(D)和双螺色满类(E)抗氧化剂的性能。通过循环伏安法测定了它们的氧化电位;用类似Stern-Volmer关系图求得各抗氧化剂和单重态氧的反应速率常数。抗氧化剂的氧化电位越小,和单重态氧的反应速率常数越大,对品红甲亚胺染料影像的防褪色效果越好,进一步证实了染料褪色的光氧化反应机理。在这些抗氧化剂中,它们的防褪色效果依次为D>E>C>B>A。

Abstract: In this paper the properties of five types of antioxidants such as phenol (A),biphenol (B),hydroquinone (C),chroman (D) and spirochroman (E) have been studied. Their polarographic oxidation half-wave potential was measured by cyclic vo-Itammetry method,and the reaction rate constant of antioxidants with singlet oxygen was obtained by analogous Stern-Volmer plot. The antifading ability of magenta azo-methine dye image was demonstrated to be more efficient both with decreasing oxidation potential of antioxidants antioxidants with singlet oxygen.of dye image.fading of dyeAmong these and with increasing reaction rate constant of It was further verified the photo-oxidation mecha-antioxidants the order of the effect preventing image is D>E>C>B>A.

Key words: magenta azomethine dye, antioxidants, stability of colour image, fluorescence spectrum, colour photography
