Abstract
A laminate sheet for protecting a thermally transferred image formed on one of surfaces of a material to be protected including a base material, a first bonding layer having one surface contacting one of surfaces of the base material and a second bonding layer having one surface contacting another surface of the first bonding layer and another surface contacting one surface of the material to be protected on which a thermally transferred image is formed. The base material including a base film having transparency to an extent through which the thermally transferred image can be observed. The first bonding layer is formed of polyethylene resin, ionomer resin, polyamide resin or polypropylene resin, and the second bonding layer is formed of polyamide resin or vinyl chloride/vinyl acetate copolymer. The laminate sheet of the structure described above is utilized for the formation of a pouch-card, a flash-card or the like.
