A method for the production of laminated films employing a two component non-solvent adhesive system comprising the steps of applying a thin film of a polyether having at least two terminal isocyanate groups to one of the films to be bonded, applying a thin film of a long chain compound having at least two terminal primary amino groups and a molecular weight of from 300 to 2000 to the other of the films to be bonded, the application of both thin films being in such amounts that the molar ratio of isocyanate groups to amino groups is from 1:1 to 2:1, the two component adhesive having a combined coating thickness of from 1 to 6 .mu., pressing the coated sides of the two coated films together, and recovering said laminated films. -A- |
