The present invention relates to a process for manufacturing an aqueous adhesive composition in which the following is prepared: - a first phase by mixing at least one elastomer latex and at least one phosphate salt S1; - a second phase comprising a resin based on: - at least one compound A1, chosen from: - a compound A11 comprising at least one aromatic ring bearing at least two functions, one of these functions being a hydroxymethyl function, the other being an aldehyde function or a hydroxymethyl function, or - a compound A12 comprising at least one aromatic ring bearing at least one aldehyde function, or - a mixture of a compound A11 and of a compound A12; and - at least one phenol A2. The first phase and the second phase are mixed so that the ammonia solution has a solids content of less than or equal to 0.55% of the aqueous adhesive composition.
