A laminate containing an image is produced by printing the image on a layer of a high temperature glue which has been applied to a layer of a transparent medium. The image is printed on the glue layer using carbon or a carboncontaining compound that does not flow when applied to the glue surface. The combination of transparent medium high temperature glue and image is then bonded to a substrate using a thermal bonding process to produce a laminate of the transparent medium and the substrate. The image is not distorted by the thermal bonding process, but remains clearly visible through the transparent medium. Typically the transparent medium will be a polyester film or a sheet of glass beads dispersed in glue. One or more additional layers may be bonded to the substrate to increase the stiffness of the product laminate. |
