Definitions

  • the invention relates to an identification document, which is quite proof against forgery, and more particular such a document comprising a base card with a photographic layer fastened thereto and comprising photographic reproductions, on the one hand, of a person and, on the other hand, of particulars about the person.
  • the identification document of the invention comprises in combination a base card, a photographic layer inseparably attached to the upper side of said card and containing a photographic 3,533,176 Patented Oct. 13, 1970 reproduction comprising a picture section showing the picture of a person and a text section accounting for particulars or data about said person, at least the portion of said photographic layer critical for the identification and the area of said base card supporting said portion of the photographic layer being each continuous, i.e. without any joints, said base card containing a specific inherent marking extending over both of the picture and text sections, and a transparent coating on top of and inseparably adhering to at least said photographic layer, and preferably also to the rear side of the card.
  • the said particulars or data usually comprise the signature of the person illustrated, preferably applied to a hatched area on the photographic layer.
  • a composite base card composed of one rear and one intermediate layer to which latter said photographic layer is inseparably attached, at least one of said rear and intermediate layers containing said specific marking.
  • the possibilities of forgery are minimized by providing an intermediate layer between the base card and the photographic layer, in particular if it is inseparably fastened to at least the latter one.
  • the intermediate layer may be such a barytes-containing layer as commonly used in photographic materials, but, as a principle, it may be of arbitrary kind. It should preferably be capable of receiving a signal substance which shall be more closely described hereinbelow. It may be a layer of fibre material felted together with the proper card material.
  • the base card shall be made of sheet material capable of inseparably carrying a photographic layer, obtained from a photographic emulsion, and. it may advantageously be made of fibrous material, such as paper or fine textile fabric, or of transparent or opaque plastic material, preferably of polyester type or of regenerated cellulose, such as nitrocellulose and acetate cellulose.
  • the specific marking is important for making the card itself attractive or indispensable to the counterfeiter and it should therefore preferably, but not necessarily, comprise a water-marking, preferably of the kind where some parts are light and other parts dark (hell-dunkel).
  • the specific marking may consist of impregnation, impression or inclusion of radioactive and/ or fluorescent signal substances, which may be applied in a given pattern.
  • the base card or the intermediate layer or both separately contains a signal substance which inherently or only after a certain irradiation emits a characteristic radiation which is easily detectable, preferably visible to the naked eye, without injury to the document, for instance a substance shining with a given colour at ultra-violet irradiation.
  • the controller of the authenticity of the document may have a detecting apparatus at hand and if proper signal substance is chosen this apparatus may be relatively simple and in any case easy to handle.
  • the substance may be fluorescent and thus be activated by daylight so that the fluorescence can be observed without a special apparatus in a dark or shady place.
  • the controller has an ultra-violet radiator, particularly if the substance reacts solely to the radiation from the radiator but not for other radiations, e.g. the sunlight.
  • the substance may be radioactive, in which case the detector is chosen so as to react to the specific radiation from the substance.
  • the two layers may have different signal substances.
  • the rear and intermediate layers may contain different fluorescent substances which emit, as by irradiation, light of different colours, which can easily be detected by inspection of the card from either side.
  • the base card as well as the photographic layer is unitary, i.e. they shall each be continuous and have no joints.
  • an identification document may be made such that the card itself and/or one or more of its coating layers may be jointed, provided that the joint does not pass between the portions of the person and the particulars about him in the photograph but crosses one or both thereof so that an unjointed continuous portion is available which is sufficient for the identification and is per se consistent with the purport of the invention.
  • the photographic layer must be secured against forgery by a transparent security coating or protective layer which inseparably adheres to the photographic layer, e.g. has partly penetrated into the latter.
  • the protective layer suitably consists of a lacquer, resin, or plastic deposited from a solution by evaporation.
  • the transparent coating consists of a hardenable resin or plastic in its hardened state, such as epoxi-resin. Moreover, such a coating cannot be removed without destroying the photographic layer, which can then not be restored.
  • the forgery proofness of the identification document will be considerably improved by making the transparent coating thin, preferably not substantially thicker than the photographic layer.
  • a further increased fool-proofness is obtained if in the document at least its photographic layer side is provided with at least one additional print of characteristic pattern covered by said transparent layer and extending over boh of said picture and text sections of the photographic layer, said print consisting, if desired, of fine lines as in bank notes.
  • the document may also be proof against photographic reproduction by executing one or more of the additional prints in colours different from that of the text of particulars, preferably by using combinations, of different colours to eliminate by optical filters when the document is photographed.
  • Such a combination may be, for instance, dark brown, light gray and another colour, e.g. red or green.
  • the photographic layer and/ or the rear side of the base card may have some text or marks printed thereto so as partly to penetrate into the support, which marking may be water soluble, or soluble in a solvent for the lacquer, resin, or plastic. Said print shall penetrate into the support in order that it shall not be removable without injuring of the support. If it is soluble in said solvent it will be damaged, removed or fled out, if one tries to remove the protective layer, and such a document could not very well be restored to a shape which would be taken as the original.
  • FIG. 1 shows an identification card seen from above
  • FIG. 2 shows the card according to FIG. 1 with the successive layers partly removed so as to illustrate each layer in an overlapping manner.
  • the basic card comprises a sheet of paper 1, which may be of a thickness corresponding to about g. per sqm.
  • This paper includes a light-dark water marking 2 and an additional marking 3 which may be radioactive or fluorescent.
  • On top of and intimately secured to paper 1 is a barytes layer 6 containing markings 7 which may be radioactive or fluorescent.
  • Inseparably attached to this layer is the photographic emulsion layer 10 carrying the photographic reproduction of a person and the data about him.
  • the uppermost layer 12' is the transparent coating which effectively seals the identification card. It is preferably made of a hardenable plastic material so that it can not be removed by moderate heating or solvent without destroying the underlying photographic layer.
  • the photographic layer 10 comprises a picture 15 of a person and a section containing particulars 16 and a hatched area 17 with a signature.
  • An impression stamp 21 is placed so as to cover parts of the sections of picture and text as well as of the signature.
  • the photographic layer has also an additional print 23 in the form of thin wave lines which may be carried out in different colours and possibly be more or less soluble in water or organic solvents.
  • the water marking is preferably in the form of a plurality of individual water marks about 2 cm. broad and distributed with an interspace of about 0.5-1 cm. Additional prints 23 may also be applied to the rear side of the card and a coating corresponding to coating 12 may also be applied to the rear side, which may, if desired, be provided with a thicker plastic coating as for producing a stiffer card.
  • An identification document comprising in combination a base card, a photographic layer inseparably attached to the upper side of said card and containing a photographic reproduction comprising a picture section showing a picture of a person and a text section accounting for particulars or data about said person, at least the portion of said photographic layer critical for the identification and the area of said base card supporting said portion of the photographic layer being each continuous, said base card containing a specific inherent marking extending over both the picture and the text sections, and an uppermost coating of a transparent material overlying said photographic layer and penetrating into and inseparably adhering to at least said photographic layer.
  • said base card consists of one rear layer and one intermediate layer to which latter said photographic layer is inseparably attached, at least one of said rear and intermediate layers containing said specific marking.
  • said base card is made of a sheet material of the class consisting of fibrous material, transparent plastic material, and opaque material.
  • marking is at least one of group consisting of water-marking, such as light and dark (hell-dunkel) marking, radioactive marking and fluorescent marking.
  • said transparent coating consists of material selected from the class consisting of lacquers, natural and artificial resins, and plastic materials.
  • a document as claimed in claim 1 in which at least its photographic layer side is provided with at least one additional print of characteristic pattern covered by said transparent layer and extending over both of said picture and text sections of the photographic layer, said print consisting, if desired, of fine lines as in bank notes.
  • a document as claimed in claim 1 provided with an impression stamp extending over both of said picture and text sections and penetrating into said base card, photographic layer and coating.
  • Photographic paper suitable for the identification document of claim 1 comprising a continuous base card, and a continuous photographic emulsion layer inseparably attached to the upper side thereof, said base card comprising a paper with a specific inherent marking extending over the major portion thereof and comprising at least water marking, preferably of the: light-dark type substantially evenly distributed over the card.
  • Paper as claimed in claim 12 in which said specific marking comprises a substance emitting radiation inherently, as radioactive substances, or by irradiation, as fluorescent substances.
  • said base card consists of a rear sheet of paper and an intermediate layer of barytes, said sheet and said layer containing different, specific inherent markings.
