Production of synthetic indigo dye began approximately 100 years ago in 1932 at Mitsui Mining’s chemical business, which led to the current Mitsui Chemicals Group. This is a synthetic dye for resin coloring that is manufactured using dye synthesis technology that has been passed down since then.
There are resin coloring materials that are both dye-based and pigment-based, and we have dye-based materials.
Due to their bulky chemical structure, the dyes have an anthraquinone skeleton that is highly durable against light and washing, and they also have coloring power.
Application example 1: Dyeing of various plastics
By dyeing various plastics in various forms, such as pellets, films, and sheets, you can create products with both color fastness and color development.
