Acrylic adhesive composition of the type comprising a monomeric acrylic phase and, intimately mixed with the latter, a free-radical generator and an adjuvant improving the impact strength of the cured adhesive composition and optionally other additives. The said adjuvant consists of a crosslinked polyurethane network formed in situ within the monomeric acrylic phase from a polyurethane precursor system dissolved in the said phase. This adhesive composition which after curing exhibits an improved shear strength, can be employed inter alia for the production of structural adhesive bonding.
