A process for printing on substrates, wherein the substrates are pretreated with a composition which comprises a polymer obtainable by free radical polymerization of ethylenically unsaturated compounds (monomers) (referred to below as polymer for short), and at least 1% by weight of the monomers are monomers having two carboxyl groups (dicarboxylic acid) or a dicarboxylic anhydride group (summarized below as anhydride monomer for short).
