| Résumé : |
Deep black is still a fashion color in leather, and black dyes occupy an important position in the tannery dye range. Achieving deep blacks is problematical, because the tanner has to balance a number of considerations including shade, strenght, penetration, fastness properties, application method, solubility, toxicological properties, and cost. This paper provides helpful information on how to select black dyes best suited to meet current tannery requirements. It shows a method for assessing color strength, covers the influence of diluents on properties, reviews toxicological aspects, and provides application hints and fastness property information. |
