Photochromic pigments, inks and paints

Photochromic pigments
Our expertise

To create smart photosensitive inks, paints and coatings, that change color with light, OliKrom relies on 2 smart pigment technologies:

photochromes peinture photochromique

Reversibles photochromic pigments

Color change at a defined light intensity, and color recovery when optical excitation decreases.

Color change can be induced by UV, visible and infrared light

Applications : camouflage, interactive materials that change color with light intensity.


Irreversibles photochromic pigments

Permanent color change above a given light intensity.

Color change can be induced by ultraviolet (UV), visible and infra-red (IR) light. 

Applications : optical marking of industrial pieces, creation of customizable coatings.
