大同化成工業 Company Overview

We are a manufacturer that contributes to society through color chemistry.

Our company was founded in 1922 with the aim of manufacturing and selling dyes, and for many years, we have been focused on the production and sale of color materials for printing inks. In particular, our red pigments have received high praise within the industry. In 1996, we established a trading division and began importing and selling raw materials necessary for pigment manufacturing, high-grade pigments, dyes, and related materials for UV inks from overseas. Furthermore, in 1998, we created a new division for processed pigments and started developing, manufacturing, and selling color materials for stationery, processed pigments, treated carbon, and resist inks for liquid crystal displays. Please feel free to contact us if you have any inquiries.

Business Activities

■Manufacturing and sales of organic pigments ■Import and sales of UV sensitizers and chemicals ■Manufacturing and sales of pigment processed products
