The adhesion of the ink dots on the printing materials is primary subject for the commercial printing applications of ink jet printers. This paper deals with the novel, reactive binder system for aqueous ink jet printer. The inks contain the two groups of liquid material in the different inks, which react each other and changes to solid polymer after mixed on the surface of the receiving material. The reaction is based on the Michael Addition Reaction. The reaction breaks out spontaneously under ambient temperature. The initial gelling is fast and overall reaction finishes with getting out of solvents. The both group of materials are hygroscopic, low viscous, and colorless. The polymeric materials born adheres the colorants to the surface of the receiving sheet and protects from the liquid and gaseous materials from the environments. The polymeric binder gives the various advantages on the fixing of the colorants, such as the smear resistance, water fastness, image migration, and ozone fading. The paper selectivity on printing will become smaller by adapting this system.
