Pigment classified according to chemical composition

fluorescent pigments free now no generally accepted method, the reason is a wide variety of pigments, chemical composition very different purpose is multifaceted, and therefore classified according to which method is not ideal.
More common classification is based on the chemical composition of the pigment will be divided into inorganic and organic pigments. From a performance perspective, inorganic pigments Light, heat resistance, hiding power, but not quite complete chromatography, low tinting strength, bright shade of difference, the larger part of the metal and oxide toxicity. Organic fluorescent pigments manufacturer diverse structure, complete chromatography, bright shade of pure, strong coloring, but the light resistance, weather resistance and poor chemical stability, more expensive.
