Zusammenfassung:The present invention relates to an aqueous adhesive composition, comprising a thermosetting resin based on: - at least one aromatic compound A1 comprising at least one aromatic ring bearing at least two functions, one of said functions being a hydroxymethyl function, the other being an aldehyde function or a hydroxymethyl function; - at least one aromatic polyphenol A2 comprising at least one aromatic ring bearing at least two hydroxyl functions in the meta position relative to one another, the two ortho positions of at least one of the hydroxyl functions being unsubstituted; and - at least one phenol which is substituted or unsubstituted by a single alkyl group or by a single alkenyl group and/or at least one aromatic hydrocarbon compound A3 comprising at least two aromatic rings bearing a single hydroxyl function, it being understood that at least one of the ortho or para positions of each aromatic ring is unsubstituted. Such an adhesive composition can in particular be used for assembling wooden elements.
