Patent ID: 7604338

Claim:
An ink jet recording method for recording on an ink jet recording medium comprising a support and a colorant receiving layer provided on the support, wherein the colorant receiving layer has a porous structure containing at least organic polymer fine particles, the method comprising utilizing an ink composition comprising a colored fine particle dispersion containing at least one kind of hydrophobic dye, at least one kind of hydrophobic polymer and at least one kind of organic solvent having a high boiling point, wherein a void volume per unit thickness (A/B) of the colorant receiving layer calculated by dividing a void volume A (×10 −5 ml/cm 2 ) of the colorant receiving layer at a void diameter equal to a particle size of the polymer fine particles obtained from a pore distribution curve by a nitrogen gas adsorption method, by a dry layer thickness B (μm) of the colorant receiving layer is 3.0 to 5.0 (×10 −5 ml/cm 2 /μm), wherein the colorant receiving layer is formed by: adding a cross-linking agent to at least one of a) the coating solution containing polymer fine particles and a water-soluble resin, and b) the following basic solution; applying a basic solution having a pH value of 8 or more to a coated layer, (1) simultaneously with formation of the coated layer by applying the coating solution, or (2) during drying of the coated layer formed by applying the coating solution and before falling drying rate of the coated layer; and hardening the coating layer by a cross-linking reaction.
