In this study, we designed and synthesized five water-soluble red dyes that have high color strength and color purity. We also found the suitable ink formulation recipes in order to apply the synthesized dyes for high-speed ink-jet printing process. The five red dyes were modified from perylene precursors, respectively. The perylene dyes have high tinctorial strength and superior light / heat stability. In order to improve the low water solubility of perylene dyes, sulfonic acid groups were introduced at the bay positions of perylene moiety. In addition, the different functional groups were introduced at the bay or terminal positions of the perylene moiety for improving the light fastness and the optical properties of the dyes. The molecular properties of the prepared dyes were analyzed and the ink jet printing process was conducted after the appropriate ink formulation. In addition, the washing, rubbing, and light fastness of the printed textiles were investigated. |
