Abstract C.I.Pigment Yellow 155 (Y 155) is an important bisacetoacetarylide disazo yellow pigment with a unique structure, which has the potential to be an alternative for benzidine yellow pigments due to its superior solvent resistance and light fastness. It is essential to investigate the crystal structure of Y 155 to understand the relationship between the structure and technical performance. Y
摘要 CIPigment Yellow 155 (Y 155) 是一种重要的双乙酰乙酰基双偶氮黄颜料,具有独特的结构,由于其优异的耐溶剂性和耐光性,有可能成为联苯胺黄颜料的替代品。必须研究 Y 155 的晶体结构,以了解结构与技术性能之间的关系。Y 155 在三斜 P 1 ( — ) 空间群中结晶。该分子以双酮腙形式存在,这与双偶氮乙酰乙酰苯胺颜料(二芳基黄)一致。与未取代的类似物 (BADA) 不同,Y 155 分子由于更强的分子内氢键而近似为平面。在 Y 155 晶体中,每个分子在上下两个相邻层中交错排列。
