Abstract
Abstract A method for producing an information carrier in the form of a card, such as an identification card or pass, as well as an information carrier produced in accordance with this method. The information carrier comprises a plurality of plastic layers combined with one another into a block, at least one of which contains a photograph of the bearer and/or his fingerprint and/or other readable or machine-readable data in the form of a photographic layer. This photographic layer is produced and incorporated into the sandwich of plastic layers making up the identification card in that a specially prepared film is exposed to light, developed, fixed and dries, and then the carrier layer of this film sandwich is removed from the emulsion after the emulsion has entered into an adhesive bond with a first plastic carrier layer, this adhesion being substantially greater than the adhesion of the emulsion to the film's auxiliary carrier, which is to be removed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
141 words
An information carrier in the form of an identification card, consisting of a multiplicity of plastic layers bonded together in a block, which comprises at least a first covering plastic layer, an adhesive layer on one side of said at least first covering plastic layer, a developed photographic emulsion including multiple types of visible information data secured by a first side onto said one side of said at least first plastic layer by said adhesive, a second carrier plastic layer applied onto a second side of said developed photographic emulsion, all of said layers are bonded together to form said identification card, whereby said emulsion extends to the outer edges of said identification card between said carrier and covering layers having a continuous edge in the vicinity of the edges of the card, said continuous edges being of water repellent quality.
Claim 2
Dependent Claim
141 words
An information carrier in the form of an identification card, consisting of a multiplicity of plastic layers bonded together in a block, which comprises at least a first covering plastic layer, an adhesive layer on one side of said at least first covering plastic layer, a developed photographic emulsion including multiple types of visible information data secured by a first side onto said one side of said at least first plastic layer by said adhesive, a second carrier plastic layer applied onto a second side of said developed photographic emulsion, all of said layers are bonded together to form said identification card, whereby said emulsion extends to the outer edges of said identification card between said carrier and covering layers having a continuous edge in the vicinity of the edges of the card, said continuous edges being of water repellent quality.
Claim 3
Dependent Claim
59 words
An information carrier according to claim 1, which includes an accessory auxiliary carrier foil having approximately the same thickness as said photographic emulsion attached to one side of said photographic emulsion only between said photographic emulsion and one side of said first or second plastic layers, said accessory auxiliary carrier foil resulting from developing stages of the photographic emulsion.
Claim 4
Dependent Claim
132 words
An information carrier in the form of an identification card, consisting of a multiplicity of plastic layers bonded together in a block, which comprises at least a first covering plastic layer, an adhesive layer on one side of said first covering plastic layer, a developed photographic emulsion including multiple types of visible information data secured by a first side onto said one side of said at least first plastic layer by said adhesive, a second carrier plastic layer applied to a second side of said developed photographic emulsion, all of said layers are bonded together to form said identification card, said first and second covering carrier plastic layers are made of polyvinyl-chloride and said first and second plastic layers are directly attached to said developed photographic emulsion by intermediate adhesive layers only.
Claim 5
Dependent Claim
132 words
An information carrier in the form of an identification card, consisting of a multiplicity of plastic layers bonded together in a block, which comprises at least a first covering plastic layer, an adhesive layer on one side of said first covering plastic layer, a developed photographic emulsion including multiple types of visible information data secured by a first side onto said one side of said at least first plastic layer by said adhesive, a second carrier plastic layer applied to a second side of said developed photographic emulsion, all of said layers are bonded together to form said identification card, said first and second covering carrier plastic layers are made of polyvinyl-chloride and said first and second plastic layers are directly attached to said developed photographic emulsion by intermediate adhesive layers only.
Claim 6
Dependent Claim
59 words
An information carrier according to claim 3, which includes an accessory auxiliary carrier foil having approximately the same thickness as said photographic emulsion attached to one side of said photographic emulsion only between said photographic emulsion and one side of said first or second plastic layers, said accessory auxiliary carrier foil resulting from developing stages of the photographic emulsion.
Claim 7
Dependent Claim
149 words
An information carrier in the form of an identification card consisting of a multiplicity of plastic layers bonded together in a block, which comprises at least a first covering plastic layer, an adhesive layer on one side of said at least first covering plastic layer, a developed photographic emulsion including multiple types of visible information data secured by a first side onto said one side of said at least first plastic layer by said adhesive, a second carrier plastic layer applied to a second side of said developed photographic emulsion, all of said layers being bonded together to form said identification card, whereby said photographic emulsion is arranged within an enclosure between said at least first covering plastic layer and said second carrier plastic layer and completely surrounded by edges formed by the direct adhesion of said at least first covering plastic layer and said second carrier plastic layer.
Claim 8
Dependent Claim
