Near-Infrared Visible Dyes - Photochromic Dye for Optical Lenses Change Color From Clear to Grey Under Sunlight – Topwell Detail:

Photochromic Dyes are reversible raw dyes in crystalline powder form.

Photochromic dyes reversibly change color upon exposure to ultraviolet light in the range of 300 to 360 nanometers.

Full color change occurs in just seconds when using a flash gun to 20-60 seconds in the sunlight.

The dyes change back to colorless when removed from the UV light source. Some colors may take longer to fade back to completely clear than others.

Photochromic dyes are compatible with one another and can be mixed together to produce a wider range of colors.

 Photochromic Dyes can be extruded, injection molded, cast, or dissolved into an ink.

Photochromic 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.
