Solvent dyes are colored substances that are insoluble in water and can be dissolved in organic solvents.

Chemical structure:

        azo dyes are mainly in yellow, orange, brown, and red, and there are also bright red xanthene and triphenylmethane dyes. Blue and green are mainly anthraquinone, triphenylmethane, azine, thiazine and phthalocyanine dyes. Nigrosin in the azine series is an important black solvent dye.

Divided into three series by solvent type, namely:

Solvent type:

       The solvents used are alcohols, ethers, esters, ketones, hydrocarbons and chlorinated hydrocarbons, benzene hydrocarbons, and oils, fats, waxes and the like.


(1) Insoluble in water but soluble in alcohol. Bright color, generally used for coloring alcohols, type A

(2) Special dye for oil coloring, it is U type

(3) Dyes suitable for paraffin coloring, W type.


           Solvent dyes are mainly used for the coloring of wood and plastics, but also for transparent paints, inks, fats, oils, waxes, soaps, petroleum products and aerosols: aluminum foil, leather, etc. It can also be used for the coloring of synthetic pulp.

More detail about metal complex dye:

          The molecule contains dyes that coordinate metal atoms. In addition to acid metal complex dyes, metal complex disperse dyes, metal complex neutral dyes, etc.

Note: Some dyes (direct, acidic, acidic media, reaction and other dyes) are complexed with metal ions (copper, cobalt, chromium, nickel, etc.). Soluble in water. The dyed products are more resistant to light or washing. For example, direct light-resistant turquoise blue GL and acid complex blue GGN.

         1: 2 metal complex dye is a dye that is soluble in organic solvents such as aromatics, esters, styrene, methyl propionate (almost insoluble in water).

     The main hue of 1: 2 metal complex dyes are: yellow, orange, red, blue, black, and fluorescent red (pink).

         Jiaman Qibang water-oil-soluble liquid metal complex dye is an environmentally-friendly metal complex dye modified on the basis of alcohol-soluble metal complex dye. It is the premier product in the world today. It can be infinitely miscible with water while maintaining ultra-high concentration. When dissolved in water, it is clear and transparent, without any precipitation and turbidity, and colorful.

         At present, there is a metal complex dye with a Chinese red name on the market. The color is very bright. Yufang Pigment has developed this product. Also called the flag red.
