1. A construction comprising a curable epoxy adhesive composition comprising
vi. a curable epoxy resin vii. an amine curing agent, viii a polymeric toughening agent, ix. a filler material and x. a phosphoric acid ester according to the formulawherein R represents an aliphatic or aromatic residue that contains one or more carboxylic acid ester units and/or one or more urethane units and that further contains at least one ether group and n represents an integer of 1 or 2; and
first and second substrates, wherein the first and second substrates are selected independently from each other from aluminium, steel and a resin-based composite material; wherein the curable epoxy adhesive composition is between and in contact with both the first and second substrate.
