| Résumé : |
The demands made on the heat resistance, lightfastness and moisture resistance of dyes at the high-quality end of the market are continually increasing. In addition, leather dyes also have to fulfil a variety of ecological and toxicological requirements as shown in Fig. 1.
In order to satisfy demands from the high quality sector, innovative dye manufacturers have to address three key matters :
1. the links that exist between the chemical composition and fastness of each dye have to be investigated,
2. production processes need to be optimised and implemented to ensure that dyes are free of by-products that have a detrimental effect on their fastness,
3. new dyes have to be developed in order to establish a completely new benchmark for performance if the desired standards of fastness cannot be met on the basis of existing dye chemistry. |
