Abstract
The aqueous adhesive composition comprises a resin based on at least one aromatic aldehyde bearing at least one aldehyde functional group, comprising at least one aromatic ring, and on at least one compound of formula (I): in which each group R1, R2 and R3 represents, independently of one another, an alkyl, aryl, arylalkyl, alkylaryl, cycloalkyl or hydrogen group, X represents S, O or N—R4, and R4 represents an alkyl, aryl, arylalkyl, alkylaryl or cycloalkyl group.

-15. (canceled)
An aqueous adhesive composition comprising a resin based on:
- at least one aromatic aldehyde bearing at least one aldehyde functional group, comprising at least one aromatic ring, and
- at least one compound of formula (I):
- wherein each group R1, R2 and R3 represents, independently of one another, an alkyl, aryl, arylalkyl, alkylaryl, cycloalkyl or hydrogen group,
- wherein X represents S, O or N—R4, and
- wherein R4 represents an alkyl, aryl, arylalkyl, alkylaryl or cycloalkyl group.
A process of manufacturing the aqueous adhesive composition according to claim 1, the process comprising the step of:
- mixing the compound of formula (I) and the at least one aromatic aldehyde in an aqueous solution.
The process for the adhesive bonding of two elements, the process comprising the steps of:
- applying a layer of the aqueous adhesive composition according to claim 1 to at least one of the two elements, and
- joining the two elements to one another via the layer of the aqueous adhesive composition.
An adhesively bonded assemblage of two elements comprising a layer of the aqueous adhesive composition according to claim 1 joining the two elements to one another.
