      Analysis of development trend and future trend of organic pigment industry

      The substances that show the color of a substance are collectively referred to as coloring agents, and coloring agents are mainly divided into two types: dyes and pigments. Dyes are colorants that are soluble in water or other solvents; pigments are colorants that are insoluble in water or other solvents and are mainly colored by fine particles dispersed in the medium of use. In addition to its light resistance, climate resistance, acid and alkali resistance, solvent resistance, migration resistance and other characteristics similar to dyes, pigments also have other specific properties, such as color, dyeing power, dispersion, covering power, heat resistance, water permeability resistance, warpage resistance, etc. The categories of colorants included are as follows:

      China's organic pigments industry appealed for tax rebate

      Huicong Chemical Network News: At the 2018 annual meeting of the international organic pigments industry on both sides of the Taiwan Strait, held in Shanghai from October 23 to 24, delegates said that the increase of tariffs imposed by the United States had a greater impact on the export of organic dyes in China, and they hoped that the country would resume the export tax rebate.

      Organic dyes have advantages

      Organic pigments are also divided into two main categories, natural and synthetic. Synthetic organic pigments are now commonly used and can be divided into several categories such as mono-azo, di-azo, colour precipitates, phthalocyanines and thick ring pigments. The advantages of organic pigments are their high colouring power, bright colour, complete colour spectrum and low toxicity. The disadvantages are that they are not as resistant to light, heat, weathering, solvents and covering power as inorganic pigments.

      Organic dyestuff uses and ranges

      Organic pigments are mainly used for colouring leather paints, high-grade plastic resins, paint printing, soft plastic products and synthetic fibres. Heat resistant 300-450, light resistant grade 8, migration resistant grade 5, pure and full colour, strong colouring power, good colour fastness, excellent solvent resistance, excellent thermal stability, high temperature resistance to 300 degrees, excellent weather resistance, high sun fastness, good dispersion, easy to modulate, easy to use, as a colouring pigment can modulate a variety of shades, safe and environmental protection.

      Chromoprecipitated organic pigments

      Acetic acid-derived chromoprecipitated organic pigments, including acetylacetoarylamines and pyrazolones, both of which have a yellow chromatographic colour.
