Organic pigment is a cyclic organic compound which consists of hydrocarbon. Organic pigmenthas clear shade and high color-strength. There are lots of slight differences from every manufacturerin Shade, Transparency, Color-strength and Clearness depending on its micronization technology,i.e. chemical structures and crystalline structures.
Comparing with Inorganic pigment, the hiding power, light-fastness, solvent-resistance and heat-resistance of organic pigments are poorer but color-strength is more higher, shade is brighter and more colors are available.
