Synthesis
We do not buy dyes in — we build them from the molecule. That is why we can move a colour exactly where it needs to go.
Micro-encapsulation
An encapsulation platform built under a national R&D project. Both our photochromic pigments and WATER HENNA came out of it.
Application
Paper, display, optics, cosmetics, environment. The same chemistry, re-engineered for each industry’s constraints.
Results, proven in the lab
Almost nothing escapes into the effluent unfixed — and it still holds 95% at pH 6.6.
Complete dissolution means uniform colour and fewer defects — and no airborne powder for the operator.
Two decades, in numbers
Started with Korea-made liquid paper dyes
Continuous supply to major paper mills

Colour made by chemists. Proven by data.
The harder the requirement, the more we keep to four steps. Skip one and the line will find it for you.
Define the requirement
Substrate, process temperature, pH and regulatory limits come first.
Design and synthesise
Rather than picking an existing dye, we build the molecule to fit.
Test and control colour
Reproducibility verified through CIELab coordinates and fastness testing.

- 01 Paper Dyes Liquid direct dyes for liner board, kraft and colored paper — dosed straight in, with no powder to dissolve.
- 02 Optical Lens Dyes Dip-dyeing colourants for ophthalmic lenses, where reproducible depth and colour stability decide the result.
- 03 Alignment Layer The functional coating that sets the direction liquid crystal molecules follow — engineered to work on plastic film substrates.
- 04 LC-MN Reactive Liquid Crystal A reactive mesogen that UV-cures its aligned structure in place, controlling phase retardation from a very thin film.
- 05 Heavy Metal Chelating Agents Chemically immobilises heavy metal ions in fly ash and process water — turning hazardous waste into non-hazardous waste.
- 06 Eco-friendly Deicer A Korean deicer built to melt hard and tread lightly — strong performance with minimised environmental risk.
- 07 Photochromic Dyes & Pigments Colour appears within a second in sunlight and clears fast in shade. Synthesised and micro-encapsulated entirely in-house.
- 08 Other Chemicals Intermediates and process chemicals used in dye synthesis — DASDA, PNTOSA, 70% sulfuric acid and tributylamine (TBA).
Korea’s major paper mills use Ons dyes.
Since developing Korea’s own liquid dye for corrugated paper in 2002, we have supplied liner board and kraft lines without interruption for over two decades.
A number of mills adopted the X-rite closed-loop colour control system through us — to cut dye consumption without giving up quality.
