Abstract:
An ink set for ink-jet printing on textiles, wherein each of four-color CMYK disperse dye presscakes is separately ground by a grinder with sodium polynaphthalene formaldehyde sulfonate as a dispersing agent to particles having an average diameter approximating 800 mn, subsequent to screening the particles of each dye for size, each dye is formed into a micro-emulsion ink, each micro-emulsion ink of the ink set comprising:a. a dye selected from the group consisting of C.I. Disperse Blue 60: 1.5 g., C.I. Disperse Red 92: 1.5 g., C.I. Disperse Yellow 114: 2 g., and Disperse Black, the Disperse Black being composed of:(i) C.I. Disperse Yellow 163: 1.0 g., having a formula: ##STR1##(ii) C.I. Disperse Blue 183: 1.0 g., having a formula: ##STR2##andii) C.I. Disperse Blue 183: 1.0 g., having a formula: ##STR3##b. a dispersing agent, sodium polynaphthalene formaldehyde sulfonate: 3 g.;c. a surfactant, polyoxyethylene nonyl phenol ether;d. a co-surface reactive agent, nonyl phenol polyethylene glycol ether: 2 g.;e. a polymer, di-ether carboxymethyl cellulose: 1.5 g.;f. a defoaming agent: 0.04 g.;g. a bactericidal fungicidal agent: 80 ppm; and,h. deionized water: 80 g.
