Abstract: A composition having pH of 6 or less comprises composite particles dispersed in an aqueous continuous liquid phase. Each composite particle comprises a non-cationic polymer core surrounded by a silica shell consisting essentially of silica particles having a mean particle diameter of 3.2 nanometers or less. The weight ratio of the total amount of the silica in the composition to the total polymer is in a range of 0.2 to 2.2. The composition is useful for making various articles. A method for making the composition is also disclosed.
