INORGANIC MICROPARTICLE DISPERSION, ITS PREPARATION METHOD, AND INK JET RECORDING MATERIAL USING THE INORGANIC MICROPARTICLE DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide hydrated alumina-inorganic microparticle dispersion having favorable stability; and an ink jet recording material having favorable gloss property, ink absorbability and superior ink coloring property.

SOLUTION: This preparation method of inorganic microparticle dispersion is characterized by dispersing inorganic microparticles under the presence of water-soluble poly aluminum hydroxide with basicity of 75% or more. This ink jet recording material is formed by coating an ink reception layer using the hydrated alumina-inorganic microparticle dispersion liquid, which is formed by dispersing inorganic microparticles under the presence of water-soluble poly aluminum hydroxide with the basicity of 75% or more, on at lease one face of an absorbent support medium.
