Pigment is a substance that can make an object color. Pigments are soluble and insoluble, there is a difference between inorganic and organic. Inorganic pigments are generally mineral substances. Humans have long known the use of inorganic pigments, using colored earth and ore, to paint and smear the body on the rock wall. Organic pigments are generally taken from plants and marine animals, such as Ruby blue, Garcinia cambogia, and the purple that Romans extracted from shellfish.
Mainly used in coatings, inks, printing and dyeing, plastic products, paper making, rubber products and ceramics industries. With the rapid development of downstream industries, the demand for pigments continues to expand, and the development prospects of China's pigment industry are very broad.

China's import demand for dyes and pigments has decreased. In 2011, domestic dyeing and pigment companies actively carried out technical transformation and adjusted product structure, and high-end varieties continued to increase. With the improvement of China's dye industry's position in the international dye market, dye imports have maintained a downward trend year by year. In 2011, the import of dyestuffs and pigments declined significantly. Among them, the import of dyes was 42,000 tons, a decrease of 16.5% over the same period, and a decrease of 26.2% in June; the import value was 390 million US dollars, a decrease of 10.4% over the previous year. The import volume of organic pigments was 19,000 tons, a decrease of 17.3% from 2010; the import volume was US $ 240 million, an increase of 2.1% from 2010.
