Nanoscale Aqueous Carbon Black Dispersion is a black water-based pigment with nanoscale particle size.  PHOTOCHROMIC MATERIAL Change color with UVA radiation.  THERMOCHROMIC MATERIAL Change color with temperature.  FRAGRANCE MICROCAPSULE MATERIAL Long lasting microcapsules release fragrance longer than six months.  LONG LASTING GLOW IN THE DARK MATERIAL Store light and heat from conventional sources, and glow in the dark.  INVISIBLE FLUORESCENT MATERIAL It is white or invisible under conventional visible light and appears colorful fluorescence under UV/IR light.

Interval thermochromic materials are pigments that are colored within set temperature range, and becomes colorless when temperature is higher or lower than this set temperature range.

1. Introduction

As known that leuco-dyes are colored or colorless when it is with or without color developer. By using a special formula of temperature controllers, we let leuco dyes are with color developer and becomes colored within specific temperature range. But the dyes will separate from the color developer and become colorless when temperature is lower or higher than set temperature range. This color changing reaction is reversible.
