Thermochromic inks:


It´s called photochromism the phenomenon that certain substances exhibit to change color to changes in ultraviolet radiation, either sunlight or black light, reversibly.

 

PRINCIPLE OF COLOR CHANGE IN SUNLIGHT OR ULTRAVIOLET RADIATION

 

The object with photochromic ink remains colorless in dark environments or floodlit (not UV). When the sun or ultraviolet radiation focus on the object, the molecular structure of the dye and pigment changes color displays, and when the light in question is deleted or removed, it returns to its original color, ie, color disappears and becomes almost or completely colorless.
