One of the advantages of digital printing is cost effectiveness of short runs, which allow customized and personalized goods will be produced at an acceptable price. Digital printing can save water and energy consumption, therefore the production cost and waste water will be reduced. This technology usually use four basic colourants (cyan, magenta, yellow and black) to print the patterns and shades we designed. At moment, the aqueous ink is the popular type. The ink normally includes colourants, co-solvents, humectants, surfactants, biocides, defoamers, viscosity modifiers and deionized water. The ink should have suitable viscosity and surface tension , enough storage stability, and good compatibility with printers. The main purpose of this study is to synthesis reactive magenta dyes have good hue and fastness. A series of reactive monoazo dyes derived from γacid were synthesized, the physical properties and the printing properties of the inks made from the dyes were discussed and compared with those of the commercial inks.
