Business Network

The origin of the Toyo Ink Group, a world leader in colorants, lies in our organic pigment synthesis technology. In addition, the core nano-dispersion technology of the Colorants and Functional Materials segment has been refined over a century of ink and coating manufacturing experience. This technology has gone beyond traditional color applications and has evolved into such advanced fields as color filter pastes for LCDs, color resist inks, carbon nanotubes, among many others.

Pigments, Pigment Dispersions

Organic pigments are used in a range of applications that require color, including not only different types of printing inks, paints and plastic colorants but also cosmetics, toner for color photocopiers, and inks for IJ printers.
In addition to hue and dispersion that match applications, we offer a range of properties that support commercialization processes and product applications such as weather resistance, heart resistance and safety. By doing so, we support lifestyles in which people enjoy using products with a range of colors.

Functional Dispersions

Functional materials are materials that demonstrate a variety of functions given their physical and chemical properties such as optical elements, electrical conductivity and heat conductivity. They are used in many products that are familiar to us.
In general, functional materials fulfill their functions when coated on the surface or interface of structures, or mixed into other substances and dispersed therein. A high-level dispersion technology is indispensable to evolve products so that they can be made lighter, thinner and more functional.

Plastic Colorants

Colorants add colors and functions to a range of plastic products that are familiar to us. They make products look luxurious and dignified by means of beautiful decoration. In addition, colors designated differently according to their purpose help identify items, and are also used as effective means to protect contents by blocking ultraviolet rays.
We also leverage our original compounding and dispersion technologies to provide products that add other functions such as conductivity and heat conductivity.
