| Résumé : |
This paper describes the modification of three commercially available 2,4-difluoro-5-chloropyrimidine dyes (Drimarene Brilliant Red K-4BL, Drimarene Brilliant Blue K-BL and Drimarene Golden Yellow K-2R) by the reaction of the parent dye with 4-hydroxybenzensulphonic acid sodium salt. Capillary electrophoresis was used to monitor both the course of the above reaction and to ascertain the dye stability of the dyes in an ink formulation. Inks prepared from the modified dyes showed much higher storage stability compared with the parent dye-containing inks; this was confirmed by capillary electrophoresis analysis. Inks containing the modified dyes were printed on wool fabrics and diffusion/fixation achieved by 'batching' the prints at 25 °C; high fixation values were obtained for all three modified dyes. These prints exhibited excellent colour fastness to washing, rubbing and light, the former test confirming a high degree of dye–fibre covalent bonding. |
