摘要： A process for preparing an aqueous dispersion coating material containing a resin component having a softening temperature of from 10 to 250°C, which comprises:
(1) a step of mixing various starting materials which will be coating film-constituting components, to obtain a blend material,
(2) a step of melting and kneading the blend material at a temperature of at least the softening temperature of said resin component, to obtain a homogenized material,
(3) a step of cooling and solidifying the homogenized material, followed by crushing, to obtain coarse particles, and
(4) a step of wet-pulverizing the coarse particles in an aqueous dispersant, to obtain an aqueous dispersion coating material containing fine particles having an average particle size of at most 10 µm.摘要翻译： 构成成分，得到 - （1）将各种起始原料的工序whichwill被涂布膜：一种用于在wässrige分散体涂层材料制备含有具有10至250℃，该方法包括的软化温度的树脂组分的方法 眩光材料，（2）熔化的步骤，和在至少所述树脂组分的软化温度的温度下捏和掺合物的材料，以获得均质的材料，（3）冷却的步骤，和固化该均质材料，其次是 粉碎，以获得粗颗粒，和（4）的步骤湿式粉碎中的粗颗粒在wässrige分散剂，以获得在含有上的至多10微米平均粒径的微粒分散wässrige涂层材料。
