Abstract: The present invention provides a method for producing dry organic pigment, comprising the successive steps of, in this order: a first step wherein a wet organic pigment is obtained by drying an organic pigment presscake at 70 to 150° C. to a moisture content of 5 to 30%, and a second step wherein a dry organic pigment is obtained by pulverizing and drying the wet organic pigment at a temperature that is higher than the temperature employed in the first step but lower than the decomposition temperature of the organic pigment. The method for producing dry organic pigment enables the dry organic pigment to be obtained with superior productivity while consuming less energy than conventional methods.
Abstract translation: 本发明提供一种生产干有机颜料的方法，其包括以下顺序的顺序：第一步，其中通过将有机颜料滤饼在70至150℃下干燥获得湿有机颜料，其湿度含量为 5〜30％，第二步，其中通过在比第一步骤中使用的温度高但低于有机颜料的分解温度的温度下对湿有机颜料进行粉碎和干燥获得干燥的有机颜料。 干燥有机颜料的制造方法能够以比现有技术更少的能量消耗更少的生产率获得干燥的有机颜料。
