Clariant - Colourants and Optical Brightening Agents
Clariant has some of the most technologically advanced dye and pigment products available to the papermaker today. With state of the art production processes, Clariant is able to offer colourants with excellent environmental profiles. The goal is to have stable formulations based on active content and water only with a "zero contribution to effluent" policy.
COLOURANTS AND DYES

Cartasol® F & K dyes: highly substantive direct dyes, specially developed for the paper industry. They are particularly suitable for dyeing woodfree paper and board in the stock and at the size press.
Cartasol® HP Range: a range of highly substantive anionic direct dyes with extremely good environmental profiles.
Cartasol® M Dyes: cationic dyes which are suitable for dyeing mechanical and waste-based furnishes.
Carta®: specially selected, conventional, anionic, substantive direct dyes for dyeing sized and unsized woodfree papers.
Cartazine: traditional, basic dyestuffs which are suitable for dyeing mechanical and waste-based furnishes.
Diresul® P: liquid sulphur dyes of the Diresul P product range are distinctly different from conventional sulphur dyes, primarily due to their improved toxicological profile.
