Dye and Pigment Intermediates
Dye intermediates are organic compounds or mixtures and downstream products of petroleum. After further synthesis, they can be used in textiles, paints, plastics, paper, printing inks, and leather. Dyes have been divided into different categories according to standards such as color, source, chemical structure and application method. Some popular dye intermediates are acid orange, yellow and acid black dyes, malachite green crystals, basic magenta lumps and anthraquinone type intermediates. They are also important raw materials for acid dyes, direct dyes and reactive dyes. It is very important to protect these chemicals.
The increasing demand for dye intermediates in textiles and the widespread use of dye intermediates in printing inks are some of the factors driving the development of the dye intermediates market. This has prompted companies to increase the production of dye intermediates. In addition, the easy availability of raw materials is expected to drive the demand for dye intermediates in the near future.
In addition, dye intermediates are also important raw materials for acid dyes, reactive dyes and direct dyes. The main application of dye intermediates is in hair dyes. Two dye intermediates widely used in hair dyes are p-phenylenediamine and p-toluenediamine.
What is the difference between dyes and pigments?
The colorant is a dye or pigment. Technically speaking, the difference is that the dye is a soluble matrix material, usually water, while the pigment is not. Another difference is that the dye does not scatter light and appears transparent. On the other hand, pigments do scatter light, so they are opaque.
