Mica is a naturally occurring mineral that is prized for its sheet-like structure and ability to reflect light. When ground, it forms a fine powder that can be used as a pigment. In addition to pure mica, many pearlescent pigments incorporate other materials, including titanium dioxide, iron oxide, and various plasticizers, which enhance their color and brilliance. The combination of these elements can create a wide array of colors and finishes, making them appealing for a multitude of applications.

Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.
