Abstract
Provided is an aqueous ink for ink jet containing a pigment and a resin particle that disperses the pigment. The cumulative 50% particle size of the resin particle in a volume-based particle size distribution is 10 nm or less. The resin particle has a crosslinking structure. The ratio of the cumulative 50% particle size of the pigment in a volume-based particle size distribution to the cumulative 50% particle size of the resin particle in a volume-based particle size distribution is 3.0 times or more to 8.0 times or less. Also, provided are an ink cartridge and an ink jet recording method using this aqueous ink.
Claims9
An aqueous ink for ink jet comprising a pigment and a resin particle that disperses the pigment, wherein
- the resin particle is adsorbed to the pigment,
- a cumulative 50% particle size of the resin particle in a volume-based particle size distribution is less than 10 nm,
- the resin particle has a crosslinking structure, and
- a ratio of a cumulative 50% particle size of the pigment in a volume-based particle size distribution to the cumulative 50% particle size of the resin particle in a volume-based particle size distribution is 3.0 times or more to 8.0 times or less.
