What are Irreversible Inks or Permanent Color Change Temperature Pigments?
High Temperature Activated Irreversible, White to Color Ink
Permanent change thermochromic ink is a high temperature activated, permanent change, colorless to color water based Screen, Flexo ink or pigment. It offers a gradual color change that becomes denser as the temperature increases.
These aqueous concentrates and inks are thermochromic pigments which develop color when heated above a given activation temperature. They are a combination of Leuco Dyes, Color Developers and Melt Materials all blended together and then micronized to reduce particle size. This is then combined into a carrier forming an aqueous concentrate which changes from off white to a color permanently when heated above its rating. As temperature increases, color density increases.
