Photochromatic Pigments react to changes in light levels and are activated by Sunlight. Photochromatic pigments will not fade in UV light, as they are dependent on UV for activation. You will not see a color change with indoor lighting only UV (Sunlight). They have several industrial applications such as graphic art, plastics, invisible inks and paints. 

Photochromatic Dyes can be extruded, injection molded, cast or dissolved into an ink. Photochromatic dyes can be used in various paints, inks and plastics (PVC, PVB, PP, CAB, EVA, urethanes and acrylics). The dyes are soluble in most organic solvents. 

Due to the wide variations in substrates, product development is solely the responsibility of the customer.
