DAINICHISEIKA COLOR & CHEMICALS MFG. CO., LTD.

DAINICHISEIKA COLOR & CHEMICALS MFG. CO., LTD. demonstrates a strong focus on materials, with Coating Compositions (Paints, Inks) representing over half (53.3%) of its portfolio, experiencing an 83.3% growth in 2025 before a sharp decline so far in 2026. While several polymer-related categories saw significant growth in 2025, such as Polymer Additives (+150.0%) and Polymer Synthesis (Polycondensation) (+200.0%), the company shows a surprising emerging interest in Printers & Typewriters with one patent so far in 2026, a category previously unaddressed in the last three years.
