Provided are an aqueous ink for ink jet capable of recording an image having excellent abrasion resistance and glossiness and an ink cartridge and an ink jet recording method using the aqueous ink. Provided is an aqueous ink for ink jet including a coloring material and a plurality of resins (first resin and second resin) different from the coloring material. The first resin is a resin particle formed of a first polyester resin and the second resin is at least one of (i) a block copolymer containing an A block having no acid group and a B block having an acid group and (ii) a second polyester resin having a sulfonic acid group. Further, an ink cartridge using the aqueous ink and an ink jet recording method in which the aqueous ink is ejected from an ink jet recording head to record an image on a recording medium are provided.

Aqueous ink, ink cartridge and ink jet recording method

To provide a recording medium in which the ink absorbability and the color development properties of an image to be obtained are high and in which cracking in an ink receiving layer is sufficiently suppressed. A recording medium contains a base material and an ink receiving layer containing inorganic particles and a binder, in which the inorganic particles have an organosilicon structure having a quaternary ammonium group, an imino group or a substituted imino group, and a hydroxyl group.

Recording medium and silane coupling agent

An aqueous ink for ink jet, the aqueous ink including a pigment and a resin for dispersing the pigment. The pigment is impregnated with a compound having a structure in which at least two structures each represented by General Formula (1) are bonded by a glycoside bond.
