LAMINATING METHOD OF FILM AND LAMINATE FABRICATED USING THE SAME

摘要

PURPOSE: A film lamination method and a laminate formed by using the same are provided to minimize the appearance deformation of a base film in a laminating method which uses ultra violet (UV) hardening and to form a laminate by minimizing the appearance deformation of the base film in the laminating method which uses UV hardening. CONSTITUTION: A film lamination method comprises the step of coating a composition for an bonding layer on a first base film; the step of laminating a second base film on the composition for the bonding layer; and the step of hardening the composition for the bonding layer by irradiating the composition for the bonding layer with light emitted from a UV light emitting diode (LED). A laminate comprises the first base film, a UV hardened bonding layer, and the second base film. The first or the second base film is a film that has more than 50% of transmittance in UV LED emitting wavelength. The UV hardened bonding layer is formed by the hardened composition for the bonding layer which includes a UV hardening resin; a monofunction monomer or a polyfunction monomer; or the mixture of the UV hardening resin and the monofunction monomer or the polyfunction monomer; and a photopolymerization initiator. The UV LED emitting wavelength is X ± Ynms; X is 365, 385, 400 or 415; and Y is 0<=Y<=50.
