Abstract
A stable silica sol having an SiO concentration of 1 to 50% by weight and containing liquid-medium dispersed moniliform colloidal silica particles each having 3 or more as a ratio of D /D of a particle diameter (D nm) measured by a dynamic light scattering method to a mean particle diameter (a particle diameter measured by a nitrogen absorption method: D nm) where D is 50 to 500 nm, and which are comprised by spherical colloidal silica particles having a mean particle diameter of 10 to 80 nm and metal oxide-containing silica bonding these spherical-colloidal silica particles, and in which the spherical colloidal silica particles link in rows in only one plane, process for producing such and a coating composition for ink receiving layers containing such a silica sol and an ink jet recording medium.
