What's the Optically variable Pigment ?

Product description: The flake powder pigment is a layer of transparent metal oxide ultra-thin films with different refractive indices. Through a precise physical vapor deposition process, an optical interference multilayer film with specific color change characteristics is formed, which is formed after crushing Effect pigments with very small particle size. Based on film multi-beam interference and floppy color effect, it forms dynamic and dreamlike color gloss.

Application: ink, paint, plastic, automotive OEM and refinish paint, cosmetic color additive etc
