<p>A method for ultraviolet curing an adhesive layer in a thermal transfer film is disclosed. The method includes the following steps: sticking the adhesive layer on a surface of printing stock through heating and pressurizing; peeling a carrier layer in the thermal transfer film to transfer an image layer in the thermal transfer film onto the surface of printing stock; and further curing the adhesive layer by subjecting to an ultraviolet radiation. The adhesive layer comprises prepolymer, reactive diluents, resin, curing agent and additives. The curing agent comprises cationic photoinitiator and free-radical photoinitiator. This method has the advantage of good curing effect, improved adhesive performance, lower curing shrinkage rate and excellent image surface smoothness.</p> |
