An identification article comprises a core (6); at least one image bearing sheet (3) secured to the core; and an adhesively secured envelope (1) surrounding the core and the or each sheet. The image (5) on the sheet is formed by at least one diffusible dye. No adhesive (2) contacts the image (5) so as to prevent diffusion of the dye into the adhesive. In an alternative construction (Fig. 3) the adhesive layer (24) is devoid of adhesive in the area of the image (22). In a further alternative (Fig. 5) a transparent barrier layer (28) overlies the image (22). <IMAGE> |
