Abstract

The invention relates to a process for the heat-sealing of a plastic substrate against a metal substrate by means of a heat-sealable coating composition which comprises a film-forming dispersion built up from at least two different polymer types A and X, each having different adhesive properties, in an organic solvent system L, with the proviso that polymer type A is free from acid groups and polymer type X has a maximum acid number of 120 mg of KOH per gram of polymer, that the dispersion, in addition to the two polymer types A and X, contains a polymer built up from components which correspond to the two polymer types, and that additional primers for the substrates to be coated are not used during the heat-sealing.
