    有机颜料晶体行为和颜色性能的关系——Ⅰ.联苯胺系黄色颜料

    • 摘要: 合成了系列联苯胺系黄色双偶氮颜料。采用X-射线粉末衍射枝术考察了它们的晶体行为,并关联了其颜色性能。发现C.I.颜料黄14和63为异质同晶体,C.I.颜料黄17存在同质多晶现象。测色结果表明:颜料的晶体行为对颜料的颜色性能具有重大影响。

       

      Abstract: A series of dichlorobenzidine Yellow pigments were synthesized. The crystal behaviours of the pigments were examined via X-ray power diffraction technique and then correlated with their colour properties. It was found that G. I, Pigment Yellow 14 and C. I. Pigment Yellow 63 are isomorphs and G. I. Pigment Yellow 17 is existed in polymorphs. The colour measurments demostrate that the change of the crystal type of pigment will signifcantly influence the colour property of pigment.
