Abstract: Plastisols useful for automobile undercoatings, anti-noise compositions, adhesives, sealing compositions and coatings for untreated, pretreated, phosphated, primed and prelacquered metal bases are improved by the addition of coke dust and coal dust fillers. The carbon dust fillers have a particle size of about 0.5 to 1000 microns and they are used in a concentration of about 9 to 90% by weight based on the total weight of plastisol and carbon dust. The carbon dust filled plastisols have a specific gravity of about 1.1 to 1.3.

Abstract: A weather-resisting extruded rubbery article based on carbon black-incorporated EPDM rubber substrate having on the surface thereof a thin layer of a colored rubbery material of a smooth or suede-like appearance integrally formed on the substrate by extrusion molding, characterized in that the colored rubbery material has been derived from 75-0% by weight of EPDM and 25-100% by weight of a graft copolymer of EPDM and vinyl chloride together with one or more coloring fillers.

Abstract: The invention comprises an oriented multi-layer film having a different orientation distribution between at least two layers and a novel process for forming oriented multi-layer films having a different orientation distribution between the layers. An important feature is the formation of a first tubular layer which is folded and fed into the interior of a second tubular layer of smaller diameter. Upon inflation of the inner tubular layer of larger diameter to its maximum unstretched diameter the smaller diameter outer tubular layer will be stretched and will also be oriented if the stretching occurs while the temperature of the smaller diameter outer tubular layer is maintained within the orientation temperature range of that material.

Abstract: The invention relates to a flexible two-dimensional material, as well as to a method and an apparatus for the production thereof.

Abstract: Security paper with narrow band luminescing authenticity characteristics which can only be excited in substantially the same wavelength region in which it also emits. With these authenticity characteristics therefore the authenticity signal is overlapped or covered by the test signal of several orders of magnitude stronger. The authenticity of the security papers cannot accordingly be tested with the normal processes or devices for determining of luminescence. The test devices used take advantage of the decay behavior of the luminescence emission for detection. The authenticity characteristics can be added to the paper material, the printing ink used, further mottling fibres or security threads.

Abstract: Polyvinyl alcohol based release coating compositions for strippable substrates which are in contact with pressure sensitive adhesives are disclosed. Substrates coated with the release compositions are easily peeled from pressure sensitive adhesive coated substrates without substantially adversely affecting the adhesive character of the adhesive coated substrate. The release coating composition comprises polyvinyl alcohol, a migratable release promoting agent, a water soluble salt of a coordinating metal and a water soluble boron compound in an aqueous solution. In addition to composites comprising release coated substrates affixed to adhesive coated substrates, the release compositions can be applied to the backing of a pressure sensitive adhesive tape to permit facile uncoiling of the rolled tape product.

Abstract: A multilayer thermoplastic sheet suitable for thermoforming into containers, the sheet being simply and expeditiously prepared and provided with consistent and reliable bonds between layers in a single process step by coextruding a polyolefin having moisture barrier properties with a high impact polystyrene layer, to provide heat sealability, a printable surface, and quick and inexpensive thermoforming for the multilayer sheet.

Abstract: A water-proof photographic support comprising a paper sheet coated with a polyolefin on both surfaces thereof, in which the paper sheet contains an alkylketene dimer, a cationic polyacrylamide and an anionic polyacrylamide.

Abstract: A container for X-ray films is of the type wherein at least one side of the film is contacted by a stratum of fluorescent material. The fluorescent material is biased against the respective side or sides of the film by two layers which consist of ferromagnetic and/or magnetic material, flank the film and attract each other. Such layers can be applied to the inner or outer sides of sheet-like carriers consisting of synthetic plastic material. The aforedescribed film, stratum or strata, layers and carriers may but need not be inserted into the space between the rigid or flexible walls of an envelope. The envelope can be dispensed with if the carriers consist of opaque material. Since each of the two carriers can support the respective layer and the respective stratum of fluorescent material, the thickness of the entire package is minimal and the film can be placed into close proximity of one or more objects to be imaged so as to obtain sharp images of such object or objects.

Abstract: A composition adapted for processing into stretch wrap film. The composition comprises between about 40 and about 90% by weight of a high molecular weight copolymer of ethylene and vinyl acetate containing between about 4 and about 25% by weight of repeating units derived from vinyl acetate and having a melt index of between about 0.1 and about 4.0. The composition further comprises between about 8 and about 55% by weight of a linear copolymer of ethylene and a higher alkene. Such linear copolymer has a specific gravity of between about 0.917 and about 0.945. The invention further includes stretch wrap film, a method of producing stretch wrap film of differential cling properties, and a composite film constituted of a layer of the aforesaid ethylene vinyl acetate copolymer and a layer of the liner copolymer of ethylene and a higher alkene.

Abstract: An improved X-ray lithography mask has been fabricated by forming an X-ray absorbing lithography pattern on a supporting foil of hydrogenated amorphous carbon. The substrate foil is formed by depositing a carbon film in the presence of hydrogen onto a surface having a temperature below 375.degree. C. The hydrogen concentration is maintained sufficiently high that the resulting film has at least one atom percent of hydrogen. A film having about 20 atom percent of hydrogen is preferred. While impurities are permitted, impurities must be maintained at a level such that the optical bandgap of the resulting film is at least one electron volt. A film with an optical bandgap of about 2 electron volts is preferred.

Abstract: A polymeric article, at least part of which is dimensionally-recoverable, preferably heat-recoverable, has, bonded to the surface of a dimensionally-recoverable portion thereof, a pliant, adhesive-receptive polymeric film which is soft at the temperature at which the dimensionally-recoverable portion is recovered, and which is substantially non-curable at ambient temperatures. The polymeric film is preferably based on a film-forming chlorinated resin or a film forming silane.The articles may be recovered over objects such as electrical equipment to provide electrical insulation and may be bonded to the object or other article with an adhesive without the necessity of any special surface treatment immediately before bonding.
