Abstract: This invention relates to a light-sensitive laminate comprising a light-sensitive layer of photoresist, a support therefor, and an intermediate protective layer preferably of a light-transmitting material disposed between said photoresist layer and said support. In use, the photoresist layer of the laminate is adhered to a base material and the support stripped therefrom, thereby leaving a composite comprising the base material, photoresist layer and intermediate protective layer disposed over said photoresist layer. The intermediate layer serves to protect the photoresist layer from damage such as by abrasion or otherwise during processing, thereby permitting storage of the so-formed composite prior to use. Since the intermediate layer may be of a light-transmitting material, photo-imaging may take place through the intermediate layer with the intermediate layer subsequently removed by contact with a solvent that is a non-solvent for those areas of photoresist left after development.

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.

Abstract: A method of manufacturing a water-release transfer is disclosed in which a design in a photopolymerizable ink is applied to a substrate having a water-soluble release coating and the design is subjected to photopolymerizing radiation, e.g. ultra-violet light, to cause the ink to polymerize to a solid state. Preferably the ink comprises a mixture of a liquid unsaturated monomer and a viscous or solid prepolymer, and one or both of the monomer and prepolymer contain acryloyl or methacryloyl groups. The invention includes water-release transfers manufactured using photopolymerizable inks.

Abstract: A dry release transfer is disclosed in which a releasable layer is adhered to a carrier sheet and a stress-resisting transferable design layer is printed on the releasable layer. The releasable layer is normally pre-stressed so that when an external force is applied to the carrier sheet , e.g. by rubbing with a stylus, this force is transmitted to the releasable layer. Since the releasable layer cannot yield to the applied force by stretching, because it is held by the stress-resisting layer, the adhesive bond between the releasable layer and the carrier sheet is weakened or is ruptured or partial or complete cohesive failure occurs within the releasable layer, thereby facilitating transfer of the design layer. A method of producing such transfers is also disclosed.

Incorporation of a photopolymerizable, ethylenically unsaturated compound provides photosensitive dispersions useful for making relief and planographic printing plates, photoresists, and the like.

Abstract: A photographic processing sleeve is provided for receiving and processing a dye donating instant film sheet to produce a photographic print. The sleeve comprises a film retaining sheet that is folded over along its lateral edges to form channels which slidably receive the film sheet, and edge strips, sometimes called side rails, which space the film sheet from the image-receiving sheet. After processing, at least a major portion of the image-receiving sheet, including the finished picture, is adapted to be peeled apart from the rest of the sleeve which can then be discarded.

Abstract: A photographic processing sleeve is provided for receiving and processing a dye donating instant film sheet to produce borderless photographic prints. The sleeve is constructed of first and second sheets coupled together to form a pocket therebetween for receiving the film sheet. One of the sheets includes a central section which carries materials for immobilizing the dyes donated by the film sheet to form a visible picture in the central section. A stripping sheet forms an outermost surface of one face of the sleeve and releasably couples the central section of the first sheet to the remainder of the sleeve so the stripping sheet and the picture in the central section can be stripped away from the remainder of the sleeve.

Abstract: A dry release transfer is disclosed in which the design layer is formed by printing one or more inks onto a carrier sheet, at least one of the inks being a photopolymerizable composition, and subjecting the design layer to ultra-violet radiation or an electron beam discharge in order to polymerize the photopolymerizable ink. By suitable selection of polymerizable components of the ink so that the photopolymerized ink has a high Young's modulus, a stress-resisting design layer is produced which will release readily from the carrier on mechanically stressing the carrier, e.g. by rubbing lightly with a ball-point pen.

Abstract: A method of making signs is disclosed in which a photographically sensitive material is imagewise exposed and developed. The developed image is so constituted that, under the action of heat and pressure, it may be made to adhere to a surface of a transparent or translucent sheet, e.g. of plastics or glass, to form a sign in which the legend is visible through and protected by the sheet. In order to render the legend more visible, a coating or layer may be applied over the legend which accordingly forms a background to the legend as viewed through the sheet.Production of the legend photographically gives very great flexibility in terms of letter size, spacing and the like and allows the production of "one off" signs on a rapid and economic basis. A simple hot press may be used to adhere the legend to the sign sheet.

Abstract: Cloth, such as cotton, burlap, or canvas, has a photographic emulsion laminated thereto, along with an outer protective film. The composite laminate formed is permanent, and sufficiently firmly affixed to the cloth that the cloth is machine washable without substantial damage or alteration of the laminated image. The method of making the cloth laminated with photographic emulsion comprises applying the photographic emulsion facedown on a protective film, coating with adhesive and applying the cloth, drying the emulsion and cloth and pressing between plates, at least one of which is heated. By dipping the emulsion in a stripping solution prior to applying to the protective film, adherence and permanence of the laminate formed is substantially increased.
