HIGH-SATURATION SCARLET COLOR DYE INK FOR HIGH-SPEED INKJET PROCESS

Highly saturated scarlet dye ink for a high-speed inkjet process and a method of preparing the highly saturated scarlet dye ink are disclosed. In particular, an ink composition according to the present invention includes a dye including a compound represented by Formula 1, and further includes, in addition to the dye, distilled water, a surfactant, and an additive. The ink composition develops a highly saturated scarlet color that is unable to be developed by existing inks for digital textile printing (DTP), and has high water solubility, excellent heat resistance, and light-fastness, and thus may be effectively used as dye and ink for a high-speed inkjet process.

The synthesis and characterisation of the perylene acid dye inks for digital textile printing

Five perylene acid dyes were synthesized to manufacture water-based inks for the high-speed ink jet printing process, including digital textile printing. All the synthesized perylene dyes exhibited superior stability and optical properties compared to a commercially used azo dye. Their water solubility was efficiently enhanced by introducing bulky and hydrophilic substituents to ensure excellent long-term stability when formulated as water-based inks. The water-based inks with these perylene dyes showed outstanding print clarity with the colours different from the basic colour composition of the existing digital textile printing inks. They also exhibited good ejection performance and helped conduct well-controlled pattern printing when used in a commercial ink jet printing machine.

A "green" route to perylene dyes: Direct coupling reactions of 1,8-naphthalimide and related compounds under mild conditions using a "new" base complex reagent, t-BuOK/DBN

The direct coupling reactions of 1,8-naphthalimide compounds efficiently occurred at 130 or 170 °C without the intervention of the leuco form dyes in the presence of base complex reagent, t-BuOK/1,5-diazabicyclo[4.3.0]non-5-ene (DBN), to give the corresponding perylene dyes in good yields with >95% purities. A possible mechanistic speculation for these oxidative coupling reactions is briefly discussed.
