They deal with the most important chromic phenomena--photochromism, thermochromism, ionochromism, and electrochromism--by describing the physico-chemical principles underlying the color changes and discussing the molecular structure of the most important colorant classes.

Moreover, the use of PCM microcapsules can simulate the efficacy of other functionalities obtained by microencapsulation technology, such as thermochromism or photochromism, because this material can be easily measured by using a fast and simple technique (differential scanning calorimetry) before and after washing cycles.

Chromazone is the company's reversible temperature sensitive ink that changes color within the range of what LCR Hallcrest refers to as "touch sensitive temperature." The special effect of the ink changing color works on the principle of thermochromism. Scientifically, here's how it works: A solvent in a solid state, along with an organic acid and a colorant, are placed in a polymeric microcapsule.
