Abstract:
A method of producing an ink jet recording material having one or more ink receiving layers formed on a substrate, wherein at least one of the ink receiving layers is formed by the steps of:mixing a cationic-resin into an aqueous dispersion of pigment particles to cause the pigment particles to agglomerate with each other and the dispersion to exhibit an increased viscosity, and to prepare an agglomerated pigment dispersion;pulverizing and dispersing the agglomerated pigment dispersion to adjust the average particle size of the pulverize-dispersed agglomerated pigment particles to 1 .mu.m or less, to provide a coating dispersion;coating or impregnating a substrate with the coating dispersion; anddrying the coated or impregnated coating dispersion on or in the substrate to form the ink receiving layer.
