PROBLEM TO BE SOLVED: To provide an ink composition for inkjet for forming a developer layer of carbonless copy paper by an inkjet recording system.SOLUTION: The ink composition for inkjet contains a salicylic acid-based developer, a water-soluble organic solvent, and water, wherein the salicylic acid-based developer has a volume average particle diameter of 0.5 μm or less and a content of at least 1 mass%, and the salicylic acid-based developer is dispersed. The salicylic acid-based developer is one or two or more selected from the group consisting of zinc 3,5-di(α-dimethylbenzyl)salicylate, zinc salicylate trihydrate, zinc 3-(α-methylbenzyl)-5-(α,α-dimethylbenzyl)salicylate, and zinc 3,5-di-(α,α-dimethylbenzyl)salicylate. A recorded matter is recorded using any of the ink compositions for inkjet by an inkjet recording system.
