Abstract: α-type copper phthalocyanine pigment containing some substituted copper phthalocyanine was synthesized. Its crystalline phase stability was studied using IR spectra, XRD and ESM. Its tinctorial power, specific surface and anti-flocculation were measured. The results show that α-type copper phthalocya-nine pigment containing some RRNO2S-and Br-substituted and some polymerized copper phthalocyanine in aromatic hydrocarbons can inhibit the change in crystalline phase and is resistant to floeculation.

摘要： 本文研究了带有部分基团取代的α型铜酞菁颜料的合成方法,采用红外光谱、X衍射、电镜扫描对其晶相稳定性进行了研究,并测试了其着色力、比表面积和抗絮凝性能.结果表明:掺入部分—SO_3NR′R、—Br取代及部分聚合铜酞菁,均能使α型铜酞菁在芳香烃溶剂中具有抗晶型转变和抗絮凝的优点.
