The latest market quotation of solvent dye

Solvent dye is most suitable for various plastic materials coloring, with greater color strength, better fastness to heat, light, acid and alkali. This range of Solvent dye is generally used in coloring domestic plastic materials, cop tube materials, fat dyeing, lacquers, inks and master batches dyeing. Some of Solvent dye is suitable for dyeing chemicals fiber, such as dacron, nylon and cellulose acetate fiber. Solvent dye has good solubility and miscibility in organic solvents.
In ancient, people usually extracted the coating from plants and animals. China is one of the first use of natural dyes country in the world. About 4000 years ago, would sericulture silk reeling, dyed various colors. Indigo, alizarin, Chinese gall and carmine and so on are the earliest application of natural dyes in ancient China. Modern industrial production of organic dyes has only 100 years of history. Fist aniline purple dye was synthetized in 1856 by English chemist Perkin, and it was used for wool and silk dyeing. And in 1901, German chemist invented the VAT blue, it was the fastness dyes of cotton. And in 1956, appeared reactive dyes. Since 1960s, with the large number appearance of synthetic fibers, it has promote the development of various types of dyes, dyes has reached the practical application of more than 1000 kinds, and almost instead all kinds of natural dyes.

  1. Solvent yellow 124: it can be easily hydrolyzed with acids, splitting off the acetal group responsible for its solubility in nonpolar solvents, and yielding a water-soluble form which is easy to extract to water. Like a similar methyl orange dye, it changes color to red in acidic pH. Solvent yellow 124 can be easily detected in the fuel at levels as low as 0.3 ppm by extraction to a diluted hydrochloric acid, allowing detection of the red diesel added into motor diesel in amounts as low as 2-3%.
  2. Solvent red 24: it is a kind of fat-soluble dye, it is also a diazo dye which can be used for the staining of lipids, triglycerides and lipoproteins on frozen paraffin sections. Solvent red 24 has the appearance of reddish brown crystals with melting point 199 °C and maximum absorption at 520(357) nm.
  3. Solvent green 3: it is also called Quinizarine Green SS, it is a kind of green dye, it is an anthraquinone derivative. Solvent green has the appearance of a black powder with melting point of 220-221 °C. It is insoluble in water. Solvent Green 3 is used for adding greenish coloring to materials. It is used in cosmetics and medications. It is used in some colored smoke formulations, in both old and new ones; when inhaled, Solvent Green 3clears very slowly from the lung, with half time of 280 days.

Market Dynamics:
The EU REACH have been formally implemented in June 1, 2008. It is a new trade barrier including technical barriers, environmental barriers and social barriers. In accordance with the regulatory requirements, dyes and organic pigments need to increase the nature of the basic characteristics of information including the physical and chemical properties, toxicological and ecotoxicological properties. In addition, it also set a number of data indicators. Dye and organic pigment in China are lack of the above data, it gives the dyestuff industry in our country to deal with the EU REACH regulation has brought many uncertain factors and difficult. However, with the development of technology at home and abroad, Chinese solvent dye market will soon be out of this predicament.
