ABSTRACT:
Color-filled debossed indicia are provided on metal substrates. Colored tape comprising a layer of resinous film and a layer of thermoset adhesive wherein the film may be colored, the adhesive may be colored, or an additional layer of acrylic paint may be provided between the film and the adhesive, is interposed between indicia dies and the metal substrate during debossing. A portion of tape corresponding to the indicia is sheared away and deposited on the surface of the indicia. The conversion of kinetic energy to heat during the debossing operation is sufficient in some applications to permanently bond the tape to the metal substrate by means of the thermoset adhesive. If necessary, the tape may be heat treated and cooled to permanently bond the tape to the metal substrate.
