Aqueous fluorescent ink, ink cartridge and ink jet recording method

Abstract

Provided are an aqueous fluorescent ink with which a fluorescent color image having an excellent color developability and lightfastness can be recorded, and an ink cartridge and an ink jet recording method using this aqueous fluorescent ink. The aqueous fluorescent ink contains a resin particle dyed with a fluorescent dye, and a quinacridone pigment. The fluorescent dye includes a basic dye having a xanthene skeleton. The resin particle has a cyano group-containing unit. A mass ratio of a content (% by mass) of the quinacridone pigment to a content (% by mass) of the fluorescent dye is 1.0 times or less. The ink cartridge includes an ink storage portion storing this aqueous fluorescent ink. An image is recorded onto a recording medium by the ink jet recording method comprising ejecting the aqueous fluorescent ink from an ink jet recording head.
