When exposed to light, a chemical reaction darkens the film to produce an image. No. Color pigments are sensitive to light. Silver halide 2. dry silver process. Carbon copies are usually made on crisp, semi-translucent paper. The light-sensitive elements of conventional photographic materials are crystallites principally of the bromide or chloride salts of silver. The silver halide recording element can contain any of the silver halide emulsion layers known to those skilled in the art, particularly those useful with X-rays. The process differs significantly from the other color transparency processes in use today in terms of both complexity and processing steps. The light sensitivity of the silver halides is key to the photographic process. The process of the invention can be used for photographic silver halide recording materials, particularly in medical diagnostics with x-rays and in reprography. Such developers are preferred for use in roll development machines, because of their stability, activity, and efficiency (see, for example, L. F. A. Mason, "Processing Chemistry", Focal Press, London and New York 1966, page 151, Table). Silver nitrate — Silver nitrate …   Wikipedia, Silver bromide — chembox new OtherNames = bromargyrite bromyrite silver(I) bromide Section1 = Chembox Identifiers CASNo = 7785 23 1 Section2 = Chembox Properties Formula = AgBr MolarMass = 187.772 g/mol Appearance = Pale yellow solid photosensitive Density =… …   Wikipedia, Silver — This article is about the chemical element. If color photocopies are displayed, they should be exposed to no more than 5,000 ft-c hours (50,000 lux hours) per year with a 3-year rest between displays. When carbon copies are found along with their corresponding top copy sheet, this usually indicates that it was an outgoing document. C 41, also known as CN 16 by Fuji, CNK 4 by Konica, and AP 70 by AGFA, is the most popular film process in use, with most photofinishing labs devoting at least one machine to this… …   Wikipedia, E-6 process — The E 6 process (often abbreviated to just E 6) is a Photographic processing system for developing Ektachrome, Fujichrome, and other color reversal (slide) photographic film.Unlike some other color reversal processes (such as Kodachrome K 14)… …   Wikipedia, Alternative process — The term alternative process refers to any non silver based photographic printing process. New Castle, DE: Oak Knoll Press. 2009. Copying, in this arena, refers to the production of a small batch of copies from an original. & Streeter, W.W. (1999). Pure silver has the highest electrical and thermal conductivity of all metals and has the lowest contact resistance (Nordberg and Gerhardsson, 1988).Because of these properties, silver has been used in a wide variety of applications. It has been found that the above problem can be overcome by developing photographic silver halide recording elements containing nonionic, fluorinated surfactants using a developer containing at least 15 g/L of a dihydroxy benzene compound and at least 0.15 mole/L of an alkali metal sulfate and a wetting agent as described below. English-German reprography dictionary. Diazo Film. ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNOR:STERLING DIAGNOSTIC IMAGING, INC.;REEL/FRAME:010628/0082, Free format text: (a) a commentary on a particular subject. Silver-halide print films are of two types: Polarity reversing and direct-duplicating. Process for developing photographic silver halide recording elements containing nonionic fluorinated surfactants using a developer containing at least 15 g/L of dihydroxy benzene compound, 0.15 mole/L of alkali metal sulfate and a wetting agent as described in a concentration of at least 0.1 g/L at a pH of no greater than 11.5. These spots appear in various shapes and sizes, irregularly spaced. Experience has shown that the binder resins in xerographic copies are vulnerable to blocking to adjacent surfaces with heat or pressure. Fluorinated, nonionic surfactants within the scope of the invention useful in the photographic silver halide recording elements have molecules that are composed preferably of a polyalkylene oxide portion and a partially or wholly fluorinated alkyl or aryl portion, connected by a bridge, for example, an ether or sulfone carbamide bridge. The process has been used since the 1920's. Diazo prints are highly sensitive to light. 3 (a) and (c) are correct. Silber Halogen Verfahren n.; Halogensilber Verfahren n. English-German reprography dictionary. The following example illustrates but does not limit the invention. Sheets, 35×43 cm, of the various test films were exposed so that their optical density after processing was between 1 and 2. These are generally more easily soluble in weakly alkaline developer solution than cationic or nonionic wetting agents. (c) Organizations are public rather than private. Because the resin binders are thermoplastic polymers with low softening temperatures, avoid storage under conditions of heat and/or pressure. Silver-halide film should not be stored with other kinds of film. Black text is generally carbon pigment in a wax or oil base, and it will appear unfaded. EXAMPLE "Smith, John". Carbon copy text will lack the embossed quality of the directly typewritten top copy. The success of the system depends upon the particular physical properties of the silver halides, such as their bonding and electron structure, the dielectric properties, the point defect structure, and the electronic transport characteristics. The silver coating weight on each side was 2.6 g/m2. Hectographs were made using aniline dyes that are highly sensitive to light. Assigned to STERLING DIAGNOSTIC IMAGING, INC. In cases of black-and-white text copy, the paper is often plain uncoated copy paper. (a) h-index (b) benchmark ... (3) (a) and (c) are correct. The process, introduced in about 1880, superseded the wet collodion …   Universalium, reversal process — noun : a photographic process in which the reverse of the image formed by direct development is obtained (as by destroying the primary developed negative image with a bleach and developing the residual silver halide to form the reversed image) *… …   Useful english dictionary, Collodion process — An old deteriorated wet plate featuring Theodore Roosevelt The collodion process is an early photographic process.
