Ink-jet recording sheet, ink-jet recording method and preparing method of ink-jet sheet

An ink-jet recording sheet comprising an ink-absorbing layer having a first porous layer at the outermost position of the ink-absorbing layer,

• wherein the ink-absorbing layer comprises water-insoluble organic fine particles which is capable of being dissolved in or swelled by a water-soluble alcohol-type organic solvent having an SP value in a range of from 18.414 to 30.69 (MPa)½ and a boiling point of not less than 120° C.

An ink-jet recording method comprising steps of jetting an ink having a water-soluble dye, water and water soluble organic solvent onto an ink-jet recording sheet comprising a first porous layer at the outermost position of the ink-jet recording sheet in an amount of 10 to 35 μm, and drying the at room temperature until reaching a constant state, wherein the ink and the ink-jet recording sheet satisfy the following Formula (3),

• Va/Vb≦4 Formula (3)
• wherein Va represents a water transition amount of a first area of the ink-jet recording sheet, where the ink is provided in said amount, during a contact time of 0.8 seconds when the first area is subjected to Bristow's Measurement, and Vb represents a water transition amount of a second area of the ink-jet recording sheet, where the ink is not provided, during a contact time of 0.8 seconds when the second area is subjected to Bristow's Measurement.

An ink-jet recording method of jetting an ink comprising a water-soluble dye, water and a water-soluble alcohol-type organic solvent having an SP value in a range of from 18.414 to 30.69(MPa)½ and a boiling point of not less than 120° C. onto an ink-jet recording sheet comprising a first porous layer at the outermost position of the ink-jet recording sheet, wherein the first porous layer contains a water-insoluble organic fine particles, which is capable of being dissolved in or swelled by the water-soluble alcohol-type organic solvent, as a primary component.
