TCN was created in 1963 and I am the third leader after Claude Rousseau, the founder, and François Rousseau, his son.

For over 60 years, we have made the world more colorful!

Our clients use the products we manufacture in post-processing, to dye any polymer and polish acetate.

They particularly appreciate the ease and speed of implementation of our coloring and polishing processes, whose impact is significant and cost-controlled.

We work with major players and SMEs around the world.

Valérie Weil, CEO of TCN

A History of Colors

TCN was born in 1963 from the meeting of a passionate chemist and a craftsman from Oyonnax in the Auvergne-Rhône-Alpes region.
This close collaboration made it possible to develop a New Chemical Technique for coloring glasses.
This process quickly gained popularity among cellulose acetate users in the region.
Hair ornaments, costume jewelry, and buttons are some examples of objects colored by this method.
Many fields of activity such as art, advertising, and even 3D printing have adopted this coloring technique.
