Organic color pigments are materials which alter the color of transmitted or reflected light due to wavelength absorption. The process differs from phosphorescence, fluorescence and other types of luminescence, in which a material emits light. These pigments are used for the production of printing inks and are derived from the derivatives of coal tars, hence generally referred to as "Coal Tar Colors", as compared to inorganic color pigments which are produced from mineral sources. Unlike inorganic color pigments, organic color pigments are described chemically by their complex ring structures. On the basis of their class, organic color pigments are segmented into azo pigments, high performance pigments, and phthalocyanines among others, where azo pigments dominate the industry. However, azo pigments along with phthalocyanines are also known by their limited profit margins due to strong competition from lower priced imports, while other pigments such as high performance pigments are known for having higher profit margins. On the basis of applications, organic color pigments are widely used in plastics, textiles, coatings and printing inks among others, where printing ink leads the industry. In addition to these, organic color pigments are also used in the automotive industry. After the global economic slowdown in 2009, the global market for automotives started to rise again, which has also been a prominent factors for the growing demand for organic color pigments.
