    摘要： Inks are disclosed wherein the ordinary mixed light color of the ink is a color substantially different than the fluorescent color of the ink. Methods of use include detection of at least the fluorescent wavelength of the ink or detection of both the ink colors when irradiated for fluorescence and by exposure to mixed light.

    摘要： Alkyd-compatible second binder resins for use in traffic paint formulations are prepared from an alkylstyrene, an alkyl acrylate and butadiene by graft polymerization of alkylstyrene and alkyl acrylate onto a preformed alkyl styrene-butadiene substrate. The product resins, comprising 50% to 90% by weight of an alkyl styrene, 0.5 to 5% by weight of a conjugated diene and 29.5 to 10% by weight of an alkyl acrylate, are employed in reflectorized alkyd traffic paint formulations to provide enhanced compatibility with aliphatic solvents, rapid drying, good wear properties, and improved retention and reflectivity.

    摘要： NEW DAYLIGHT FLUORESCENT PIGMENTS WHICH CONTAIN AN ORGANIC FLUORESCENT DYESTUFF AND AS RESIN A CONDENSATION RESIN, CONSISTING OF COPOLYMERIZATES OF OLEFINICALLY UNSATURATED COMPOUNDS CONTAINING EPOXY GROUPS AND HENCE COPOLYMERIZABLE VINYL COMPOUNDS WHICH ARE CROSS-LINKED WITH DI- OR POLYCARBOXYLIC ACIDS OR THE ANYDRIDES THEREOF AND A PROCESS FOR THEIR PREPARATION WHICH COMPRISES INCORPORATING THE ORGANIC FLURRESCENT DYESTUFF INTO THE CONDENSATION RESIN. THESE DAYLIGHT FLURESCENT PIGMENTS MAY BE EMPLOYED FOR PREPARING FLURESCENT PAINTS, FOR EXAMPLE AIR-AIR-DRYING LACQUERS ON THE BASIS OF AKYL RESIN OR PHYSICALLY DRYING LACQUERS ON THE BASIS OF ACRYLIC RESINS, AS WELL AS FOR PREPARING FLURESCENT PRINTING INKS SUCH AS INKS FOR SCREEN PRINTING INTAGLIO PRINTING, BOOK PRINTING AND OFFSET-LITHO PRINTING. DE TO THEIR HIGH RESISTANCE TO HEAT, THEY ARE PARTICULARLY SUITABLE FOR FLUORESCENT DYEING OF PLASTICS AND ENAMELS.

    摘要： Readout process and apparatus for reading coded symbols in a code in which the components are narrow band photoluminescent compositions. The symbols, on suitable substrates such as paper tape, labels on cans, bottles and the like, are illuminated by flashes from a xenon tube with an ultraviolet transmitting filter. The flashing tube is aimable so that it can be directed either on a window in front of which tape containing the symbols is passed or through another window onto containers with labels and the like. Suitable optics are moved into position so that the different locations of the substrate do not change the image path length. When the symbols are illuminated with successive ultraviolet flashes, they luminesce in the visible in the different narrow band colors corresponding to the different components and this is imaged on a filter wheel having the same number of filters as there are components: four for numerical work or six for alphanumeric work. After passing through the filter wheel, the visible beam is imaged on the cathode of a photomultiplier tube. The filter wheel also is provided with magnets which open switches connecting the photomultiplier tube to different circuits for each filter and also generate a trigger pulse which triggers the flashes of the xenon tube in synchronism with the positioning of each filter by the rotation of the wheel. The signal from the photomultiplier tube passes through amplifiers, one for each filter, and into logic circuits which provide for gates to select the particular signal from a particular filtered beam and also start readout at the beginning of a symbol and reset after the filter wheel has made a second full revolution during which no signals are received. Response of each amplifier is delayed about 20 Mu sec. so that the extremely short-persistence fluorescence from such compounds as optical brighteners and the like has died out and response is only from the slower decaying photoluminescence of the narrow band code components. The logic circuits send out coded signals corresponding to the code to display mechanisms, such as Nixie tubes, or a permanent recording, such as a solenoid driven typewriter of the computer readout type, or both, or to a solenoid driven diverter for deflection from a conveyor system.
