    Abstract: A marking comprises a layer, preferably of film-forming material, which contains a photochromic compound. The photochromic compound is capable of changing color when exposed to uv light, but can be converted to a permanently non-photochromic compound, preferably by overexposure to uv light. An image is formed in the layer by converting the photochromic compound to a permanently non-photochromic compound in one or more selected areas. When the layer is subsequently viewed under uv light a colorless image of non-photochromic compound can be seen on a background of colored photochromic compound.

  • Patent number: 4980262
    Abstract: A photographic contact printing process is disclosed having application in the mass production of replicate video discs from a master disc, and other applications wherein it is desired to replicate micro-detail over a relatively large area. A problem with conventional contact printing from a mask to a photographic medium is one of maintaining intimate contact over a relatively large area since dust, dirt, etc., are almost impossible to completely eliminate in any practical manner. In accordance with the present invention, a contact printing process is provided wherein intimate contact is not necessary for making high quality contact prints. The present invention recognizes that in contact printing information from a master disc to a replicate disc, the contact printing process is significantly less sensitive to imperfect contact between the master disc and the replicate disc if one employs a replicate disc comprising a photosensitive material having a certain optical properties.

  • Patent number: 4904576
    Abstract: Photosensitive cuprous halide-type materials, particularly cuprous chloride and cuprous bromide materials, can be prepared from an anode product material produced from electrolysis of copper in an aqueous acid halide bath. Preferably, the copper electrolysis is carried out in a dilute hydrochloric acid solution. The resulting anode product materials are particularly sensitive in the presence of a polar molecule catalyst such as water or ammonia. In one highly preferred embodiment of this invention the anode product material is treated with the aqueous solution of ammonium salt of a water soluble organic acid (e.g. aqueous solution of ammonium ascorbate); one of the chief advantages of these materials is that they are highly photosensitive when dry and can be developed from a latent image prepared thereon.

  • Patent number: 4871630
    Abstract: Disclosed is a process for reducing lithographic image size for integrated circuit manufacture. A mask of photosensitive material having an opening of a minimum size dictated by the limits of lithography is formed on a substrate. Reduction in the image size is achieved by establishing sidewalls to the interior vertical surfaces of the opening by depositing a conformal layer, followed by anisotropic etching. The dimension of the opening is reduced by the combined thickness of the two opposite insulator sidewalls.In a specific direct application of the disclosed process, a photomask/stencil having a pattern of openings of a minimum size smaller than possible by lighography, per se, is formed.

    Abstract: The lithographic printing plate of the invention comprises a substrate having a hydrophilic surface, a coating on said surface of a light sensitive material (e.g., a water soluble diazo) and a top coating of discrete, oleophilic resin particles (e.g., an emulsion polymer), the resin particle coating being:(a) transparent to actinic light;(b) sufficiently permeable to allow a developer for the light sensitive material to penetrate through to the underlying light sensitive coating;(c) insoluble in said developer;(d) capable of being coalesced in situ after the plate is imaged and developed.

  • Patent number: 4500628
    Abstract: Solid state devices are produced by dry etching of a resist film to produce a negative resist pattern. The film comprises a polymer typically containing a halogen, and at least one type of silicon-containing or nonsilicon-containing organometallic monomer. The radiation, typically X-ray radiation, locks the monomer or monomers into the polymer, with a subsequent fixing step removing the unlocked monomer or monomers in the unirradiated portion of the resist. The film is then exposed to a plasma comprising oxygen, which removes the unirradiated portion at a faster rate than the radiated portion, producing a negative resist pattern. The plasma development is typically accomplished by reactive ion etching. Sensitizers can be used to extend the wavelength response of the films, typically into the ultraviolet or visible regions.

  • Patent number: 4486518
    Abstract: A non-silver, positive-working, essentially alkali-insoluble, radiation-sensitive composition, which becomes alkali-soluble on exposure to radiation, comprising a non-silver, positive-acting, essentially alkali-insoluble radiation-sensitive component a radiation absorbing component and an essentially alkali-soluble polymeric binder. A radiation-sensitive element comprising a transparent substrate overcoated with said radiation-sensitive composition. A duplicating film comprising the said element prepared by exposing said composition through the substrate and then image-wise exposing said composition through a mask in front of the composition followed by treatment with an alkaline developer to remove those areas of the composition subjected to both exposures.

  • Patent number: 4481268
    Abstract: A method of forming a photographic azo or azamethine dye image in an exposed photographic silver halide element, the method of comprising the steps of (a) developing the imagewise exposed material to form an imagewise pattern of oxidized color developing agent, (b) reacting the oxidized color developing agent with a color coupler to produce an image dye, characterized in that at least one of the color developing agent and the color coupler possesses a metal chelating site such that the image dye is capable of forming a bi-, tri- or higher-dentate metallized dye, and (c) contacting the image dye with polyvalent metal ions to form a metallized dye image. Specified color developing agents include heterocyclic substituted hydrazides and specified couplers include benziso-oxazolones and 2H-pyrazolo-[3,4-b]pyridines in addition to more conventional compounds.

  • Patent number: 4467022
    Abstract: A photosensitive element is provided by an actinic radiation-transmissive film-forming polymeric material which contains photolabile blocked surfactant capable upon exposure to actinic radiation of releasing a detectable quantity of surfactant in actinic radiation exposed areas in areas not exposed to actinic radiation and unblocked surfactant in an image-wise pattern in the actinic radiation exposed areas. An imaging process is also provided comprising providing the actinic radiation-sensitive element and exposing the actinic radiation-sensitive element to actinic radiation in an image-wise pattern at an intensity and for a time sufficient to release an image-wise pattern of released surfactant in the exposed area.

  • Patent number: 4465757
    Abstract: Compounds of the formula I ##STR1## in which A, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are as defined in claim 1, are effective optical stabilizers for photographic dyes and their precursors. They are added to the colorphotographic recording materials as the latter are being prepared, and, as a result, the developed images have a longer optical stability.

  • Patent number: 4464448
    Abstract: A black and white microfilm reproduction is made of a person or their photograph and accompanying text data. A sheet of multicolor photographic paper then is exposed to the black and white image carried on the microfilm and to another color film carrying a multicolor security pattern, mark or the like. The paper then is developed to produce the document having a black and white image of the person to be identified and accompanying text data together with overlying multicolor security pattern. The security pattern has lines that vary in color along their lengths independently of one another.
