Document Type and Number:
WIPO Patent Application WO2004046255
Kind Code:
A3
Abstract:
The invention provides an aqueous dispersion comprising fumed silica particles, colloidal silica particles, and water. The fumed silica particles have a BET surface area of about 70 to about 140 m<2>/g, and the colloidal silica particles have a BET surface area of about 110 to about 150 m<2>/g. Also, the total amount of silica in the dispersion is about 35% to about 60% by weight, and the fumed silica particles comprise about 25% to about 80% by weight of the total amount of silica in the dispersion. The invention also provides a coating composition and a recording medium incorporating the inventive dispersion.
