The object of the present invention is to provide an ink for ink jet printers which is improved in dispersion stability. The ink is one containing a pigment and an organic solvent where a silicone graft polymer is contained in the ink and is dispersed in the organic solvent in the form of particles having a particle diameter of 0.01-0.3 μm in such a state as the silicone graft polymer being adsorbed to at least a part of the outer surface of the pigment. The pigment is an organic pigment and/or carbon black.
