The ink composition of the present invention comprises water, colorant and fine particles of a resin containing fluoroolefin units. The fine particles of resin may be preferably fine particles of fluorine-containing vinyl ether resin composed of fluoroolefin units and vinyl ether units represented by the following general formula: <IMAGE> wherein X is selected from the group consisting of F, CF3 and Cl; Y is selected from the group consisting of R2, R3OH and R4COOH; R1 is a hydrogen atom or an alkyl group having from 1 to 18 carbon atoms; R2 is an alkyl group having from 1 to 18 carbon atoms; R3 and R4 are alkylene groups having from 1 to 18 carbon atoms respectively, n and m are integers, and the ratio of m to n, m/n, is in the range of 1/99 to 99/1. The ink composition of the present invention is able to record an image of high density and superior water resistance with only a small amount of ink.
