Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
101 words
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.
Claim 2
Dependent Claim
101 words
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.
Claim 3
Dependent Claim
11 words
A card according to claim 1 wherein said backing is metal.
Claim 4
Dependent Claim
12 words
A card according to claim 2 where the metal backing is etched.
Claim 5
Dependent Claim
20 words
A card according to claim 3 further comprising a uniform layer of polyvinyl chloride coated on the metal etched surface.
Claim 6
Dependent Claim
20 words
A card according to claim 4 where said backing has been coated with solvated polyvinyl chloride colored with white pigment.
Claim 7
Dependent Claim
39 words
A card according to claim 2 wherein the adhesive is provided by a sheet of polyvinyl chloride laminated to the image support in a manner where the polyvinyl chloride only partially penetrates the support thereby rendering one surface laminable.
Claim 8
Dependent Claim
16 words
A card according to claim 6 further comprising a polyvinyl chloride surface on said metal backing.
Claim 9
Dependent Claim
16 words
A card according to claim 7 wherein said indicia bearing layer is composed of polyvinyl chloride.
Claim 10
Dependent Claim
17 words
A card according to claim 6 wherein said image support is composed of a tightly woven textile.
Claim 11
Dependent Claim
16 words
A card according to claim 7 where said fabric is composed of neutral-colored cotton fiber thread.
Claim 12
Dependent Claim
15 words
A card according to claim 6 wherein said image support is composed of spun-bonded polyester.
Claim 13
Dependent Claim
49 words
A card according to claim 6 further comprising transparent thermoplastic top cover placed over said indicia and said photographic image bearing substrate and a thermoplastic back cover placed under said backing in a manner where said front and back covers encapsulate the laminated support, indicia bearing surface and backing.
Claim 14
Dependent Claim
23 words
A card in accordance with claim 12 wherein said thermoplastic back cover is sealable to said top cover for encapsulating the laminated core.
Claim 15
Dependent Claim
22 words
A card according to claim 13 further comprising a security thread laminated between said photographic image bearing substrate and said top cover.
Claim 16
Dependent Claim
109 words
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.
Claim 17
Dependent Claim
109 words
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.
Claim 18
Dependent Claim
124 words
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.

Dependent Claim
124 words
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.
Claim 20
Dependent Claim
16 words
A card according to claim 16 further comprising a transparent, plastic covering to encapsulate the card.
