立索尔宝红合成混合颜料的研究
Study on Synthetic Mixed Pigments of Lithol Rubine
-
摘要: 采用双重氮或双偶合组分的共偶合反应,制备了多种立索尔宝红合成混合颜料。对其颜色特性的测试表明:大多数合成混合颜料具有增效作用;指出了分散状态的改变是增效的重要原因之一。Abstract: The synthetic mixed pigments of Lithol Rubine were prepared throught cocoupling reaction of two diazo-constituent or two coupler. The measure of colour property showns that: most of synthetic mixed pigments exhibit synergistic action. It was found that change of dispersive state is one of important reasons of syneigism of pigment.
