The present invention relates to a lamination method of a film and a laminate formed therefrom. More specifically, the present invention provides a lamination method of a film and a laminate formed therefrom which can minimize appearance defects of the base film and increase the degree of curing of the adhesive layer to increase the degree of lamination of the film.

UV curing is widely used in the field of patterning since it can harden the resin at a high speed compared to the thermal curing. However, the metal halide lamp or the high pressure mercury lamp used in the existing UV curing can reduce the degree of curing and generate a lot of heat due to the presence of the wavelength absorbed by the base film. This may cause deformation of the base film such as wrinkles on the base film. On the other hand, in the method of laminating two or more base films, there is a method of increasing the amount of UV light to increase the degree of adhesion between the films. However, this method can also lead to external deformations of the base film.
