A microcapsulated pigment contains, as reaction media one or more specific aliphatic acid alcohol esters obtained from monohydric aliphatic alcohols having odd numbers of carbon atoms and aliphatic carboxylic acids, these reaction media in a homogenious compatible state with chromatic components are occluded in microcapsules to obtain characteristics of thermochromism with a hysteresis range (segment HG) from 8°C to 30°C.
微胶囊
颜料含有一种或多种特定的脂肪族酸醇酯作为反应介质,这些反应介质是从具有奇数碳原子数的一元脂肪族醇和脂肪族
羧酸中获得的,这些反应介质在与色素成分均匀相容的状态下被包裹在微胶囊中,从而获得热致变色的特性,其滞后范围(
HG 段)为 8°C 至 30°C。
