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。
A series of benzidine yellow double azo pigments were synthesized. X-ray powder diffraction techniques were used to investigate their crystalline behavior and to correlate their color properties. C.I. Pigment Yellow 14 and 63 were found to be heterogeneous and inhomogeneous and C.I. Pigment Yellow 17 had a polymorphism. The colorimetric results show that the crystal behavior of the pigment has a significant effect on the color properties of the pigment.
