Photoluminescent Pigment
Photoluminescent pigment stores light (sunlight or artificial light) and emits the stored light with blue-green color in the dark (at night or during blackout). Our pigment is inorganic material which is not harmful to humans and the environment. Color of Product Light Emitting Color [Characteristics]

♦ Safe
• It is composed of ceramic substance, burned in high temperature. It is safe and non-stimulating pigment, with no radiation emission and with high chemical stability.

♦ Durable
• The pigment is an inorganic substance. UV light does not cause degradation. Its durability is semi-permanent, so it continues to store and discharge light without limit.
