  • Patent number: 4768811
    Abstract: A card with a photograph is of at least four-layer structure. The card includes: a display sheet made by printing a composite image of a portrait image and a character image such as a name on a photographic paper; a plastic frame sheet in which the display sheet is fitted; at least one plastic core sheet attached to the back surface of the frame sheet; a transparent plastic first cover sheet attached to the front surface of the frame sheet; a second cover sheet attached to the back surface of the core sheet; and an adhesive layer bonding the display sheet and the first cover sheet. The frame sheet, at least one core sheet, and the two cover sheets are made of a heat and pressure-weldable plastic such as a polyvinyl chloride resin. These four sheets are stacked one upon another, sandwiched between two ferro-type plates, and pressure-welded with heat, so that the four plastic sheets are pressure-welded with heat and the display sheet and the first cover sheet are heat-sealed.
