All products contain very low sulphide-content (less than 0.3%). This very low amount of sulphide prevents the danger of undesirable release of hydrogen sulphide during acidification. No additional safety precautions are necessary while using Diresul P dyes. Diresul P dyes give high coverage and good light fastness whilst waste waters remain practically clear. This enables their use in a multitude of applications across the whole range from decor papers up to graphic papers, packaging papers and industrial papers, combining an ecological profile with economics and industrial safety.
