Abstract

Disclosed are a method for making an ink-jet recording material which comprises adding silica fine particles having an average primary particle diameter of 50 nm or less to a dispersion medium mainly comprising water containing a cationic polymer having a weight average molecular weight of 100,000 or less and mixing to prepare a slurry of silica fine particles; dispersing the slurry of silica fine particles by a dispersing machine to prepare a dispersion of silica fine particles; mixing the dispersion of silica fine particles with at least a hydrophilic binder to prepare a coating solution for forming an ink-receptive layer; and coating the coating solution for forming an ink-receptive layer on a support and drying, a method for preparing a dispersion of silica fine particles and the silica dispersion.
