PURPOSE: Provided is a method for production of semi-cured transfer film having no damage in printing layer without forming a primer layer between ultraviolet ray cured resin layer and printing layer. CONSTITUTION: The method comprises forming releasing agent layer(2) on one side of synthetic resin film layer(1), forming ultraviolet ray cured resin layer(3) containing short wavelength photoinitiator and long wavelength photoinitiator on the releasing agent layer, semi-curing the ultraviolet ray cured resin layer by lightening ultraviolet ray having short wavelength of less than 250 nm, forming printing layer(4) on the ultraviolet ray cured resin layer, and forming thermal melting adhesive layer(5) on the printing layer. The synthetic resin film layer is comprised of polyester resin, nylon resin, polycarbonate resin, and the releasing agent layer comprised of paraffine wax or silicone releasing agent. The short wavelength photoinitiator is selected diphenylketone benzyl dimethyl ketal, 2-hydroxy-2-methyl-1-phenyl-1-on, or 4-hydroxy cyclo phenylketone.
