Abstract

The present invention relates to multicolor composite ink used for ink jet printers. Each color of the composite ink contains a coloring agent, a molecule-inducing phase separating agent, a levelling dispersing agent, a chelating agent, a pH regulating agent and additives for foaming, sterilizing, catalyzing, etc. The composite ink in different colors uses different separating agents so that ink in different colors induces phase separation during touching printing paper so as to accelerate sedimentation to reduce or prevent bleeding among different colors, and consequently, color patterns or images with high quality can be obtained. The molecule-inducing phase separating agents are water-soluble macromolecular polymers with the molecular weight of 300 to 40000, wherein the chemical and physical properties of different polymers are greatly different so as to ensure the induced phase separation action among the polymers. The present invention substantially improves the flexibility of the selection of ink pigment, and former coloring agents which are hardly used can be used by the present invention. Moreover, the composite ink has the advantages of low cost, good water resistance, no corrosion, no toxicity or damage and no environment pollution.
