Sunday 08. June 2008 - Ciba PERGASOL Brown O dyes have high affinity for paper and excellent color constancy, and minimize backwater coloration Ciba PERGASOL Orange FT dye for trichromatic brown shades facilitates compliance with tight specifications

Ciba has extended its offer of brown shades for packaging with a new, cost-effective range of anionic direct liquid dyes and a new orange component for trichromatic dyeing.

Ciba PERGASOL Brown O dyes have high affinity for paper fibers as well as excellent color constancy under different light sources, and minimize backwater coloration. Ciba PERGASOL Orange FT is a bright orange brown that provides the basis for highly cost-effective trichromatic dyeings.

“Customers now have the choice between ready-made brown dyes, which are simple to apply, and trichromatic components, which allow fulfillment of very tight shade specifications,” says Mikael Jighede, Head of Business Development & Applications, Coloration and Whiteners, in Ciba’s Business Line Paper.

PERGASOL Brown O dyes and PERGASOL Orange FT are designed for coloration of fresh and recycled paper fibers. Suitable applications include liners, sack paper and corrugated board.

Besides their other benefits, PERGASOL Brown O and PERGASOL Orange FT anionic direct dyes have environmental advantages over basic dyes, which contain high amounts of acid.

Ciba works continuously on developing products and processes that improve the properties of packaging, including wet strength, retention and coloration.
