ABSTRACT:
A process for the production of laminated films employing a two component non-solvent adhesive system, which comprises the steps of applying a thin film of at least one polyether having at least two terminal isocyanate groups and a molecular weight between 2000 and 5000 to one of two films to be bonded together, applying a thin film of at least one long chain compound having at least two reactive terminal amino groups to the other film to be bonded, the application of both thin films being in such amounts that the molar ratio of isocyanate groups to amine groups is from 1:1 to 5:1 and the two components together being present in an amount of 0.5 to 5.0 gm/m.sup.2, pressing the coated sides of the two coated films together and recovering said laminated films.
