摘要： A process for preparing a green pigment composition which comprises subjecting a mixture of a halogen-free blue pigment material and a halogen-free yellow pigment material to size reduction. The size reduction desirably comprises (1) kneading the pigment mixture in the presence of a grinding medium or (2) dissolving the blue pigment material and yellow pigment material in a strong acid to obtain a solution and injecting the solution into water to recover the pigment materials as a precipitate. This process provides a high-quality pigment composition which has a green hue completely free from the problem of shading into white and combines sufficient light resistance with sufficient heat resistance. The pigment composition obtained is highly suitable for use in the coloring of plastics required to be processed at a high temperature. It is highly safe and hygienic and does not pose an environmental problem.

摘要： A method for preparing a green pigment composition in which a halogen-free blue pigment material and a halogen-free yellow pigment material are subjected to an atomizing process in mixture, is disclosed. The atomizing process is desirably (1) a co-kneading process conducted in the presence of a grinding material, or (2) a process that comprises dissolving the above-mentioned blue pigment material and yellow pigment material in a strong acid to obtain a solution, and injecting this solution into water to obtain a re-deposited substance. The method of the present invention does not cause the "fogging" problem at all, and provides high quality green shade having sufficient light resistance and heat resistance simultaneously. The resulting pigment composition is excellent also in plastics coloring use requiring a heating process at higher temperature, and has high safety/sanitation property, and causes no environmental problem.
摘要翻译：公开了一种制备绿色颜料组合物的方法，其中无卤蓝颜料和无卤素黄颜料经过混合雾化处理。雾化方法优选为（1）在研磨材料的存在下进行的共捏合工序，或者（2）将上述蓝色颜料和黄色颜料在上述溶液中溶解，得到溶液，并将该溶液注入水中以获得再沉积物质。本发明的方法根本不引起“雾化”问题，同时提供具有足够的耐光性和耐热性的高品质绿色阴影。所得到的颜料组合物在用于需要在较高温度下进行加热处理的塑料着色用途也是优异的，并且具有高的安全/卫生性能，并且不会引起环境问题。
