A Brief History Of The Development Of Organic Pigments

  A brief history of the development of organic pigments

  Human use of pigments, has a long history. Archaeologists have found that humans have begun to use colored inorganic matter three thousand years ago, such as the use of Hequhe, hematite as a "color material" for painting purposes, which can be made by ancient frescoes , Rock paintings are proven. This as a "color material" used in He Shi, hematite, in fact, is the most primitive inorganic pigments.

  When the use of organic pigments from when, it is difficult to determine the exact age, because the ancient organic pigments are easy to fade, it is difficult to retain so far. In ancient times, as a supplement to inorganic colors, humans used botanical colorings (such as madder, indigo) or animal color (such as Tyler, from a conch). Since the colorants were extracted from the flora and fauna, the biologists called them Pigment, the words of today's pigments. The word Pigment comes from the Latin Pigmentum, which is the pigment extracted from the roots of a plant called Pingere. Modern scientific research shows that the colored components of madder are mainly alizarin (1,2-dihydroxyanthraquinone), and the colored component of indigo is mainly indigo (Indigo). These two substances or their derivatives are still used as pigments. Of course, from today's point of view, these organic materials are soluble, they should be classified as dyes rather than organic pigments, but at least they are the origin of modern organic pigments.

  By the middle of the nineteenth century, the large-scale rise of synthetic dyes, which also laid the foundation for the synthesis of organic pigments. Organic pigments are accompanied by the development of the dye industry and gradually developed.

  In 1856, the British chemist Perkin prepared the first synthetic dye, that is, aniline violet (Mauveine); 1858, the German chemist Griess found aniline diazotization reaction, in 1861 Mene found an aniline diazonium salt and aromatic amine Or aromatic phenolic coupling reaction, began to synthetic dyes and organic pigments.
