Irreversible Thermochromic Material
A. Principle
By using microencapsulation technology, the leuco-dyes, color developers, and temperature controllers are encapsulated and made into pigments.
As heating up to customized temperature, the color appears irreversibly even cooling down.

D. Notice：
1. Avoid adding solvents and contacting acidic substance. If it’s necessary to increase the viscosity of inks, please dilute with pure water.
2. Avoid printing on varnished(oil-coated) paper.
3. Dry at low temperature(air-drying) and avoid heat drying to prevent irreversible coloration.
4. The inks and printed products should be sealed and kept in dark and cool dry place, or refrigerated storage to prevent UV aging or ink spoilage that will affect color-changing function.
