Abstract
Provided is an identification card having a photographic image support, the lower layer of which is impregnated with a hot-melt type thermoplastic adhesive, and a laminable indicia bearing layer and a durable resilient backing to which the support and bearing layer are laminated.
Claims17
An identification card, comprising
- (a) a laminable, photographic image support selected from the group consisting of a spun-bonded polyester and a tightly-woven fabric including an upper layer impregnated with a light-sensitive photographic emulsion for reproduction of a photographic image thereon, and a lower layer impregnated with a hot melt thermoplastic adhesive having bonding characteristics of polyvinyl chloride,
- (b) a laminable, identification indicia bearing layer,
- (c) a durable resilient backing adapted to have said support and said indicia bearing layer laminated thereto where upon application of sufficient energy irreversible bonding of said support and indicia bearing layer to said backing is effected.
An identification card, comprising
- (a) a photographic image support having intersticies and voids and an upper and lower surface, said support selected from the group consisting of spun bonded polyester and a tightly woven fabric, said support enabling migration of a photographic emulsion into said intersticies and voids proximate to said upper surface, said support further incorporating a hot-melt thermoplastic adhesive impregnating said lower surface,
- (b) a laminable, identification indicia bearing layer,
- (c) a durable resilient backing adapted to have said support and said indicia bearing layer laminated thereto where upon application of sufficient energy irreversible bonding of said support and indicia bearing layer to said backing is effected.
An indentification card, comprising
- (a) a laminable photographic support, said support being selected from the group consisting of spun bonded polyester and tightly woven fabric, said support permitting migration of a photographic emulsion therein,
- (b) a durable resilient backing,
- (c) a layer of hot melt adhesive disposed between said support and said backing, said adhesive being capable of impregnating at least a portion of said support and uniting said backing and support at lamination conditions,
- (d) a laminable, identification indicia bearing layer adapted to laminate to said backing at lamination conditions,
- (e) whereupon positioning said support and layer on said backing and establishing lamination conditions renders said adhesive flowable to irreversibly bond said support to said backing and said layer laminates to said backing.
