PROBLEM TO BE SOLVED: To provide a polymer binder composition to improve the durability of inkjet images.SOLUTION: The inkjet ink binder contains polymer nanoparticles (PNP) having an average diameter in the range of 1-50 nanometers. These PNP contain a curing composition in a standard amount of 1-20 % based on the amount of the dried polymer. The reaction of the curing composition can be initiated by heating, chemically or by chemical rays. The inkjet ink composition containing a liquid medium, a coloring agent and an inkjet binding agent is provided and also the method of improving durability of inkjet ink printed on a base material is provided.
