摘要:
The ink composition for ink jet recording according to the invention includes a coloring material, a cyclic ester, a first organic solvent having a flash point of 70° C. or less and represented by Formula (I): R1—O—(R2—O)2—R3 (I) (wherein, R1 represents an alkyl group having 1 to 4 carbon atoms; R2 represents an ethylene group or a propylene group; and R3 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms), and a second organic solvent having a flash point of 90° C. or more. The cyclic ester has a content “a” (% by mass) of 6% by mass or more and 30% by mass or less. The content “a” (% by mass) of the cyclic ester, the content “b” (% by mass) of the first organic solvent, and the content “c” (% by mass) of the second organic solvent satisfy a relationship represented by Expressions (1) and (2): a
