  • the resin support sheet whereon the hydrophilic colloid layer(s) containing the information to be protected is (are) coated has preferably a thickness in the range of 0.050 to 0.75 mm for allowing its manipulation in a mechanical printing process, e.g. offset or intaglio printing.
  • the transparent resin support Before or after being coated with the necessary hydrophilic colloid layer(s) for imaging purposes the transparent resin support can receive itself or on said layer(s) security or verification marks in the form of e.g. a finger print, printed patterns known from bank notes, e.g. guilloches, coded information, e.g. binary code information, liquid crystals as described e.g. in published European patent application 0 400 220, signature or other printed personal data or marks that may be applied with fluorescent pigments, nacreous pigments giving special light-reflection effects as described e.g. in US-P 4,151,666, and/or visibly legible or ultraviolet-legible printing inks as described e.g. in GB-P 1,518,946 and US-P 4,105,333.
  • the printing inks may contain dyes that diffuse partly (e.g. by heat applied applied in the lamination step) into the paper sheet and become physically or chemically fixed therein.
  • the paper sheet whereto the transparent image-bearing resin sheet is laminated may contain itself printed matter and a large variety of verification features that will be altered or destroyed when parts of the laminate are mechanically or chemically separated.
  • holographic patterns may be obtained in silver halide emulsion layers, normally Lippmann emulsions, especially designed for that purpose and can either or not be combined with a photograph.
  • the silver halide emulsion layer for producing the hologram is applied to the side of the transparent resin that is laminated in contact with a paper sheet or cover side of the passport booklet.
  • the lamination in the passport booklet of the transparent resin sheet containing an image when proceeding through the intermediary of a thermoplastic resin sheet having a softening point below 60 °C is carried out advantageously between flat plates of a pressure laminator of which one or both of the plates are heated.
  • a roll-laminator known in the art is used.
  • the lamination may proceed by putting the whole booklet containing the elements to be laminated between the pressure-exerting elements of the laminator, but in another embodiment the paper foil, for bonding thereto the transparent resin sheet containing a portrait and printed mattter, before being folded and assembled by binding is introduced in contact with said sheet into the laminator for effecting the desired bonding to the selected paper page of the lateron to be assembled passport booklet.
  • the laminated transparent image-containing resin sheet may be laminated with a topcoat to improve or reduce its permeability to water, so that the process of laminating may be carried out at one or both sides of the information carrier.
  • a transparent sheet of cellulose triacetate having a thickness of 100 ⁇ m was coated at one side with the following subbing coating
  • the subbing layer was coated with a mordant layer composition
  • the aqueous coating composition of the subbing layer contained a common spreading agent and siloxane compound No. 6 in an amount of 6.25 % with respect to ingredient A and was introduced as a 5 % solution in ethanol.
  • the above image receiving sheet was dye diffusion image transfer processed with a portrait photo-exposed photographic dye diffusion transfer material having a composition as described in the Example of US-P 4,496,645.
  • the exposure proceeded optically in such a way that a reverse reading image (mirror image of the portrait) was obtained in the image-receiving layer when seen in the direction of the image-receiving layer but right reading when seen through the rear side of the transparent cellulosetriacetate support.
  • each sheet After being wetted each sheet was contacted with a different side of the dye image receiving sheet material and kept in contact therewith for 1 minute, whereupon the sheets were separated.
  • the thus coated sheet was arrranged in a laminate assemblage containing a passport booklet paper sheet and intermediate polyethylene sheet having a thickness of 100 ⁇ m making at one side contact with the paper sheet and at the opposite side with the imaged side of the image-receiving sheet which contains a reverse reading image when seen from the side of the polyethylene sheet.
  • the lamination was carried out in a pass-through roller pair laminator pressing successive areas of the elements to be laminated
  • the obtained laminate has a sealing thus strong that even in wet state peeling apart of the cellulose triacetate sheet is no longer possible without tearing apart parts of the paper whereto the lamination took place.

Abstract

Un livret (10) pouvant être utilisé comme un passeport comprend une couverture (10F, 10R) dont la partie interne est fixée et un ensemble de feuilles de papier réunies sous la forme d'un livret et rassemblées au niveau de leur pliure par des éléments de reliure de livret se caractérise en ce qu'au moins une feuille de papier ou un côté de couverture est réuni de manière feuilletée à une feuille résineuse transparente comportant une image et/ou des caractères imprimés orientés vers la feuille de papier et pouvant être lus à l'endroit lorsqu'ils sont examinés à travers le côté de la feuille transparente éloigné du matériau auquel elle est collée. Un mode de réalisation est illustré dans la figure annexe.
