Paper Coloring Agent
Paper coloring agents provide vivid, uniform, and lasting shades for paper and paperboard. Our range includes basic, direct, and acid dyes for diverse papermaking needs.
The problem
What Goes Wrong Without It
Shade drift between batches is the complaint that reaches the mill's customer, not the mill. Mechanical pulp and chemical pulp take dye differently, and a dye chosen for the wrong furnish bleeds into white water instead of fixing on fibre.
What we supply
How The Range Answers It
Eleven dyes across two chemistries: cationic basic dyes with strong affinity for lignin-containing mechanical and semi-chemical pulp, and anionic direct dyes matched to cellulose furnish - both compatible with standard retention and fixing systems.

Orange is a shade where levelness problems are immediately visible on the reel.
