一种高着色强度的红色偶氮缩合混合颜料及其制备方法
摘要：
本发明涉及一种红色的偶氮缩合混合颜料，其由以下式3所示酰氯和式4所示酰氯的酰氯混合物，式（3） 式（4）与以下式6所示二胺、式7所示二胺和式8所示二胺的二胺混合物缩合形成，式（6）式（7）式（8）其中，摩尔比（酰氯混合物：二胺混合物）=2∶1，摩尔比（式3所示酰氯：式4所示酰氯）=15-85：85-15，摩尔比（式6所示二胺：式7所示二胺∶式8所示二胺）=0-30∶5-60∶40-95。该混合颜料着色强度高，鲜艳度良好，分散性高，耐热性良好，透明度高，着色力较单一偶氮组分制备的颜料强度提高10％以上，可以用于塑料、油墨和涂料中。
摘要（英）：

The invention relates to a red azo condensation mixed pigment, which is formed by condensation of an acyl chloride mixture composed of the acyl chloride shown in the following formula (3) and the acyl chloride shown in formula (4) and a diamine mixture composed of the diamine shown in the following formula (6), the diamine shown in formula (7), as well as the diamine shown in formula (8). Specifically, the acyl chloride mixture and the diamine mixture are in a mole ratio of 2:1, the acyl chloride shown in formula (3) and the acyl chloride shown in formula (4) are in a mole ratio of 15-85:85-15, and the diamine shown in formula (6), the diamine shown in formula (7) as well as the diamine shown in formula (8) are in a mole ratio of 0-30:5-60:40-95. The mixed pigment has high coloring strength, good vividness, high dispersibility, good heat resistance, high transparency, and has tinting strength enhanced by over 10% compared with that of pigments prepared from a single azo component, so that it can be used in plastics, printing ink and paints.
