摘要

The present invention relates to an aqueous composition for the treatment of a fibrous material in sheet comprising: - at least one alkali metal silicate, and preferably a silicate of na, k and li or a mixture of these alkali metals, - at least one mineral filler, characterized in that the mass ratio between the mineral filler and the alkaline silicate in the dry extract of the composition is to 0,25 to 4, and preferably of 0,3 to 3, and preferably from 0,5 to 1,5; the uses and associated processes, as well as the fibrous materials and manufactured articles obtained.
