ABSTRACT:
A process for adhesively bonding a substrate, using an adhesive comprising a polymer binder and a crosslinker compound I comprising carbodiimide groups, wherein the compound comprising carbodiimide groups is obtainable by reactinga) carbodiimides of 1,3-bis(1-methyl-1-isocyanatoethyl)benzene, 1,4-bis(1-methyl-1-isocyanatoethyl)benzene or a mixture thereof withb) polyalkylene oxides having at least two isocyanate-reactive groups, preferably at least two hydroxyl groups, andc) if appropriate, further compounds reactive with a) or b).
