摘要:
Photographic glass plates are advantageously prepared by a process in which the functional layers are applied to the glass plate support by lamination. In a first form of this process, a multilayer-composite comprising antihalation, silver halide emulsion and protective overcoat layers is transferred from a flexible polymeric film support to the glass support. In carrying out this first form of the process, a release layer, protective overcoat layer, silver halide emulsion layer and antihalation layer are coated, in order, on a flexible polymeric film and laminated via an adhesive layer to a glass plate having suitable thickness and flatness for use as a photographic support. The release layer is designed to have greater adhesion to the flexible polymeric film than to the protective overcoat layer, whereby the film and release layer can be stripped off prior to the plate being put into use. In a second form of the process, an antihalation layer, silver halide emulsion layer and protective overcoat layer are coated, in order, on a support material comprised of a release sheet, a very thin polymeric film and an adhesive layer interposed between the release sheet and the film, the release sheet is then stripped away and the remainder of the coated support material is laminated via the adhesive layer to the glass plate support. The process of lamination eliminates the difficult task of directly coating photographic layers on glass plates and greatly facilitates the preparation of high quality photographic glass plates in a wide variety of different sizes.

Disclosed is a photographic element having a support, at least one layer for carrying an image on the support and a protective coated layer cured by an active energy ray thereon, wherein the protective coated layer is one obtained by curing, by irradiation of an active energy ray, an active energy ray curable composition containing a prepolymer containing at least 2 epoxy groups in the molecule and a polymerization initiator which can be activated by the active energy ray; and the active energy ray curable composition is coated on the layer carrying the image; and the layer carrying the image has a water content of 20.0% by weight or less. Disclosed is also a process for preparing the photographic element constituted as the above.
摘要:
A coater applies ultraviolet curable coating material to the opposite sides of roll film by a double-sided coater which employs offset coating rolls and smoothing bars. A splice detector responds to the occurrence of a splice upstream of the coater and causes the splice region to move through the coater without applying coating material to the splice region, by lifting the emulsion side of the film off of the coating roll as the splice passes and by temporarily and sequentially interrupting the operation of the smoothing bars and the offset applicator roller on the non-emulsion or base side, concurrently with the passage of the splice therepast. In a second embodiment, the film is lifted by lifting bars off of both coating rolls and tension on the film is concurrently decreased in the coater to prevent marking of the surface of the coated film by the final smoothing bars.

摘要:
Radiation-curable compositions useful for restorative and/or protective treatment of photographic elements are comprised of a polymerizable epoxy compound, a cationic initiator for initiating polymerization of the epoxy compound, a polymerizable acrylic compound, a haloalkylated aromatic ketone which serves as a free-radical initiator for initiating polymerization of the acrylic compound, and a polymerizable organofunctional silane. Photographic elements, such as still films, motion picture films, paper prints, microfiche, and the like, are provided with a protective overcoat layer which is permanently bonded to the element, and serves to protect it from abrasion and scratches, by coating the element with the radiation-curable composition and irradiating the coating to bond it to the element and cure it to form a transparent, flexible, scratch-resistant, cross-linked polymeric layer. The protective overcoat layer can be applied to the image-bearing side of the element or to the support side of the element or to both sides. The radiation-curable composition can also be used as a restorative composition in the treatment of photographic elements which have scratches, abrasion marks, and the like, which impair the appearance or projection capabilities of the element. In use as a restorative composition, the radiation-curable composition can be applied locally in the region of the defects only, to effectively eliminate them and restore the element to a substantially defect-free condition, or it can be applied over the entire surface of the element to both eliminate the defects and form a protective overcoat layer that is capable of providing protection against subsequent scratching or abrasion.

Various objects may be maintained in their original condition or protected from further damage by physical, chemical, and biological forces by applying thereto thin, continuous, impervious coatings of vapor-deposited poly(p-xylylene) polymer or derivatives thereof. By the invention, it is possible to protect paintings, photographs, documents, articles of sculpture, silver objects, coins, fishing hooks and lures, marine fittings and hardware, batteries, fuel cells, automotive parts, water pollution control devices, logic circuits, electrical components, electric motors and parts, light bulbs, ammunitions, fireworks, glass items, decorative items, timepieces, and decorative wrought iron grillwork.
摘要:
A releasing layer is formed on a heat resistant backing sheet and a transparent thermal bonding layer is formed on top of the releasing layer to provide a coating material. The sheet of material such as photograph is mated with the coating material. When the sheet material is a photograph its emulsion side contacts the bonding layer and is passed through a heated roller assembly to bond the bonding layer to the photograph. The backing sheet and the releasing layer are then separated from the sheet material or photograph and bonding layer.
摘要:
Compositions to be applied to professional studio photographs on color paper or black and white emulsions for protective and finishing purposes comprising a vinyl resin in particulate form dispersed in methyl isobutyl ketone to which is added a blend of aromatic hydrocarbons such as naphtha and xylene, with or without a thinning or flattening agent, and a plasticizer. The compositions are also useful for preventing color changes and for making color corrections. They overcome the yellowing and other disadvantages of conventional lacquers such drying hard and cracking the photographic print.

It has been discovered that certain blends of polymers can be applied from an aqueous system to glossy surfaces and dried to yield coated surfaces that have a pleasing degree of roughness or ''''matte'''' and that are waterproof, abrasion resistant, antiblocking, and essentially completely transparent to visible light. The coatings are applied to the glossy surface in the form of an aqueous lacquer composition comprising A. WATER; B. DISSOLVED IN THE WATER, AN EFFECTIVE AMOUNT OF AMMONIUM COPOLYMER SALT OF A OF ETHYL METHACRYLATE AND METHACRYLIC ACID; AND C. DISPERSED IN THE FORM OF A LATEX THROUGH THE SOLUTION OF (B) IN (A), AN EFFECTIVE AMOUNT OF A HIGHER MOLECULAR WEIGHT POLY(VINYL ACETATE).
摘要:
A method of making a picture in which a print, preferably a photographic print produced from a transparency made from infrared color film is given a texture, if desired, by being rolled under pressure, then coated with a clear lacquer, then touched up, if desired, by application of acrylic colors, then coated again with lacquer if said colors are used, then coated by a transparent gel medium which is given a desired texture and then finally coated with a lacquer.
