Sunlight Activated Effect
Overview
Photochromic pigments are UV and sunlight-activated color changing powders that remain nearly colorless indoors and transform into vibrant colors when exposed to sunlight.
Designed for paints, inks, plastics, coatings, and creative applications, these pigments create dynamic, interactive surfaces that respond instantly to UV exposure.
The effect is fast, fully reversible, and ideal for outdoor products, smart packaging, security features, and eye-catching designs.

How Photochromic Pigment Works
Works in UV-reactive paints, inks, plastics, coatings, textiles, and outdoor applications.
Photochromic pigments contain light-sensitive molecules that react to ultraviolet (UV) light.
When exposed to sunlight or UV light:
• UV light activates the pigment at a molecular level
• The pigment changes from colorless to a visible color
• The color intensity increases with stronger UV exposure
• When UV light is removed, the pigment gradually fades back to its original state
This color-changing process is fully reversible and can be repeated thousands of times without losing performance.

Frequently Asked Questions
What is photochromic pigment?
Photochromic pigment is a UV-sensitive pigment that changes color when exposed to sunlight or ultraviolet light and returns to its original color once UV light source is removed.
What is the difference between thermochromic and photochromic pigment?
Thermochromic pigments react to temperature changes, while Photochromic pigments react to UV light and sunlight exposure.
Does photochromic pigment work indoors?
Photochromic pigments work best under direct sunlight or UV exposure. Indoor activation is usually weaker unless strong UV light is present.
Can photochromic pigment be mixed into resin or paint?
Yes. Photochromic pigments work well in clear paint, coatings, resin, varnish, plastics, and inks. Mixing ratio is 10 to 15% powder (measured by weight.
