Abstract:
1. A dispersion, obtained by a method comprising reacting a) in 50 to 75 parts by weight of water b) 25 to 50 parts by weight of silica particles having a BET surface area of 30 to 500 m c) an amount based on 100 to 300 μg/m wherein the amount of component c) is determined based on the amount of component b) as follows: the amount of component b) in terms of grams is multiplied by its BET surface area to obtain a total BET surface area in terms of m the total BET surface area is multiplied by 100 to 300 μg/m wherein the haloalkylfunctional alkoxysilane (A): (i) is of formula (I) wherein the groups R the groups R the groups R n is 0 or 1, Hal represents chlorine or bromine, and x is 0, 1, or 2, y is 0, 1, or 2, and (x+y) is 0, 1, or 2; or (ii) is a hydrolysis product or condensate of at least one alkoxysilane of formula (I); or (iii) is a mixture of at least one alkoxysilane of formula (I) and at least one selected from the group consisting of a hydrolysis product and a condensate of at least one alkoxysilane of formula (I), and wherein the tertiary amine (B) has a formula wherein the groups R
