Method of printing a laminate for production of dimensionally stable food and drink product containers with application of a primer having an excess of isocyanate groups

A method, comprising as method steps

• a) providing a sheetlike composite precursor comprising a carrier layer;
• b) overlaying the sheetlike composite precursor on an outer face of the sheetlike composite precursor with a liquid first polymer composition which comprises a first di- or polyisocyanate which has aromatic groups, a further di- or polyisocyanate which has aliphatic groups and at least one di- or polyol,
• wherein the liquid first polymer composition is characterized by a ratio of a proportion of aromatic groups in the liquid first polymer composition to a proportion of aliphatic groups in the liquid first polymer composition in a range from 0.35 to 0.80;
• c) hardening the liquid first polymer composition, thereby obtaining a first polymer layer,
• wherein the hardening is effected at a temperature of the liquid first polymer composition and/or the first polymer layer in a range from 18 to 35° C.;
• and
• d) overlaying the sheetlike composite precursor on the outer face of the sheetlike composite precursor with a liquid second polymer composition;
• wherein the first polymer layer in method step c) comprises an isocyanate content in a range from 0.1% to 50% by weight, based on the weight of the first polymer layer;
• wherein the liquid second polymer composition in the overlaying in method step d) comprises at least one first polyvinyl acetal in a proportion in a range from 2% to 12% by weight and a colorant in a proportion in a range from 2% to 15% by weight, in each case based on the weight of the liquid second polymer composition.
