PURPOSE: Provided is a pigment type ink composition for an ink-jet printer, which includes an aqueous polymer resin and can prevent a nozzle from clogging and the surface of an output object from separating. CONSTITUTION: The ink composition comprises: 2-5wt% of a pigment, which is dispersed by using 0.06-3pts.wt. (based on the pigment of 100pts.wt.) of a dispersing agent such as salts of aliphatic acid, high alkyl sulfate, polyvinyl alcohol, polyvinyl pyrrolidone, and etc.; 5-30wt% of a hydrating agent such as propylene glycol, glycerin, 1,4-butanediol, and etc.; 0.1-5wt% of the aqueous polymer resin such as acryl resin, vinyl acetate resin, styrene-butadiene resin, acryl-styrene resin and etc.; 60-92.9wt% of high pure water. |
