Temperature-sensitive color-memorizing microencapsulated pigment

摘要

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 homogeneous compatible state with chromatic components are occluded in microcapsules to obtain characteristics of thermochromism with a hysteresis range (segment HG) from 8 DEG C. to 30 DEG C.
