Substrate treatment process uses aqueous formulation(s) (I) containing (A) binder(s) obtained by copolymerization of ethylene, (meth)acrylic acid and optionally other comonomer(s) together with (i) (C) carbodiimide(s) and (D) diol(s), triol(s) and/or polyol(s) or (ii) (B) reaction product(s) of (C) with (D). Independent claims are included for (1) (I) per se; (2) preparation of (I); (3) substrates printed by this process. Verfahren zum Behandeln von Substraten, dadurch gekennzeichnet, dass man mindestens eine wässrige Formulierung einsetzt, die enthält (A) mindestens ein Bindemittel, das erhältlich ist durch Copolymerisation von Ethylen und (Meth)acrylsäure und gegebenenfalls einem oder mehreren weiteren Comonomeren, (B) mindestens einem Umsetzungsprodukt von mindestens einem Carbodiimid (C) mit mindestens einem Diol, Triol oder Polyol (D) oder (C) mindestens ein Carbodiimid und gegebenenfalls mindestens ein Diol, Triol oder Polyol.
