A method of fabricating a plastic card including the steps of printing on the rear surface thereof, laminating a sheet of clear plastic to the rear surface while simultaneously polishing the front surface, laminating a metal layer to the front surface of the sheet of plastic, and applying a protective coating of a mixture of aminocoumarin dye and clear liquid polyvinyl chloride to the surface by a silk screen process to thereby protect the metal layer against wear and abrasion. A plastic card including a central layer having a front surface and a rear surface, a layer of clear plastic sheeting on the rear surface, a metalized layer on the front surface, and a coating of cured silk-screen-applied clear liquid resin consisting of a mixture of aminocoumarin dye and clear liquid polyvinyl chloride on the metal layer for protecting it against wear and abrasion.
A method of fabricating a plastic card comprising the steps of providing a sheet of plastic having a front surface and a rear surface, applying printing to said rear surface of said sheet of plastic, laminating a sheet of clear plastic to said rear surface of said sheet of plastic, polishing said front surface of said sheet of plastic, laminating a metal layer to said front surface of said sheet of plastic to provide a shiny front surface to said sheet of plastic, printing the shiny surface of said metal layer, and applying a protective coating in liquid form to said surface of said metal layer, said protective coating comprising a mixture of aminocoumarin dye and liquid polyvinyl chloride.
A method of fabricating a laminate comprising the steps of providing a sheet of plastic having a front surface and a rear surface, laminating a metal layer to one of said surfaces of said sheet of plastic to provide a shiny surface to said sheet of plastic, applying a protective coating of a mixture liquid polyvinyl chloride and aminocoumarin dye to said surface of said metal layer, and curing said protective coating.
A method of applying a mirrored surface to a plastic sheet comprising the steps of polishing the surface of said plastic sheet, adhering a metal layer to said surface, and applying a coating of a mixture of clear polyvinyl chloride ink and aminocoumarin dye to said metal layer, and curing said coating.
A method of fabricating a plastic card comprising the steps of providing a sheet of plastic having a front surface and a rear surface, applying printing to said rear surface of said sheet of plastic, laminating a sheet of clear plastic to said rear surface of said sheet of plastic, polishing said front surface of said sheet of plastic, laminating a metal layer to said front surface of said sheet of plastic to provide a shiny front surface to said sheet of plastic, printing the shiny surface of said metal layer, applying a protective coating in liquid form to said surface of said metal layer, said metal layer comprising sheet vacuum metalized aluminum in roll form, and said step of laminating said metal layer to said front surface of said card comprising superimposing said sheet vacuum metalized aluminum relative to said front surface of said sheet of plastic, and applying heat and pressure to said superimposed sheet of vacuum metalized aluminum and said sheet of plastic.
