An ink for ink jet recording is provided which can form a record having a high color density, free from the occurrence of bleeding or feathering even on recycled paper, and possessing water resistance. An ink composition comprising a pigment dispersible and/or soluble in water without the aid of any dispersant and a glycol ether selected from the group consisting of diethylene glycol mono-n-butyl ether, triethylene glycol mono-n-buityl ether, propylene glycol mono-n-butyl ether, and dipropylene glycol mono-n-butyl ether can realize a print having no significant bleeding or feathering. Further, a high-quality image having much less bleeding or feathering can be realized by an ink jet recording method wherein a reaction solution, containing a reactant, capable of breaking the state of dispersion and/or dissolution of a pigment in the ink composition is brought into contact with the ink composition.
