Abstract
An ink composition contains (a) a compound which is represented by the following Formula (1) and has a specific molecular weight, (b) a colorant, (c) a polymer having an SP value of equal to or greater than 17 and equal to or less than 24, and (d) water, in which there is a specific relationship between a log P value of the component (a) and an SP value of the component (c). An ink set contains the ink composition, and an ink jet recording method uses the ink composition:R represents a specific alkyl group; Z1 represents a single bond, —NR1—, or —O—; Z2 represents —NR1— or —O—; at least one of Z1 or Z2 is —NR1—; R1 represents a hydrogen atom or a specific alkyl group; and L represents a specific alkylene group or —C2H4—O—C2H4—.
