1. In a method of making a thermochromic pigment, the improvement comprising:
using a sufficient amount of anionic surfactant dispersed in water to emulsify an internal phase to dimensions such that upon completing a subsequent step of microencapsulating the internal phase with a cured resin the resulting slurry contains microcapsules that have a mean by volume particle size diameter of less than 1 micron. |
