Abstract
An inkjet ink contains at least a first carbon black, a second carbon black, and water. The first carbon black has a DBP oil absorption of less than 130 mL/100 g and a BET specific surface area of less than 300 m2/g. The second carbon black has a DBP oil absorption of at least 130 mL/100 g and a BET specific surface area of at least 300 m2/g.
