FINE COMPOSITE PARTICLE DISPERSION OF CATIONIC COMPOUND-FINE SILICA PARTICLE, ITS MANUFACTURING METHOD AND INKJET RECORDING BODY

摘要

PROBLEM TO BE SOLVED: To provide the manufacturing method of a fine composite particle dispersion comprising a highly transparent cationic compound-fine silica particles and an inkjet recording body manufactured by utilizing the dispersion.

SOLUTION: This dispersion of fine composite particles comprising a cationic compound-fine silica particles is obtained by grinding fine agglomerated composite particles formed by blending the cationic compound with colloidal silica by mechanical means under the condition that at least 70% of the resultant ground agglomerated particles exists as the primary particles of the fine composite particles comprising the cationic compound-fine silica particles and less than 30% of the resultant ground agglomerated particles exists as the secondary particles of the fine composite particles formed by joining the primary particles through the cationic compound. Further, the inkjet recording body is formed by employing a coating liquid containing the dispersion of the fine composite particles under the condition that the fine composite particles are arranged in an ink accepting layer of the gloss developing layer at its topmost layer.
