Abstract: Disclosed is a method of duplicating and imaged master comprised of a marking material distributed in an imagewise manner upon a substrate. The method involves contacting the master with a highly viscoelastic inking composition comprising:A. a silicon containing block copolymer having polymeric silicone segments and polymeric segments of a material which is adhesive to the material comprising the image;B. a coloring agent; andC. a solvent in which the copolymer is soluble but which is a non-solvent for the marking material. The inked master is then contacted under pressure with a transfer member to thereby transfer the ink to the transfer member in imagewise configuration.

Abstract: A novel method of preparing a waterless lithographic master and a method of printing therefrom are provided. To prepare the printing master, a suitable ink accepting substrate such as aluminum, paper or plastic, is coated with a silicone gum curing catalyst, preferably suspended in a hydrophilic binder. A barrier fusable particulate hydrophobic image pattern is then deposited on said coated substrate and fused to mask said curing catalyst in the image areas. The substrate is then coated with an uncured silicone gum, preferably as an aqueous emulsion so that the gum does not adhere to the hydrophobic image pattern. The silicone gum is then cured in the nonimage areas to selectively provide ink receptive image areas and ink releasing nonimage areas. The method of printing comprises the additional steps of applying ink to the imaged master and contacting the inked master with an image receiving surface to thereby transfer the inked image.

Abstract: The production and use of indicia-bearing anodized layers from which the backing metal has been removed as transparent or translucent elements in articles in which the layer may be laminated to a clear or translucent layer so that the information contained in the anodized layer can be read by direct illumination rather than by reflected light.The information in the pores of this anodized article is preferably in the form of a metal image and of a metal selected from the group consisting of silver, gold, platinum and palladium which is preferably silver and which may be intensified by the electroless deposition of other metals thereon, such metals being selected from the group consisting of nickel, cobalt, iron, copper, chromium, gold, silver, platinum, palladium and mixtures thereof.Products of special interest include edge lighted panels, microfilm, microfiche, photomasks, and printed circuits.

Abstract: A web of indeterminate length carrying thermally transferable material, usually referred to as hot stamp tape, is structured to provide an improved simulated wood grain pattern on a substrate after transfer to the substrate of transferable portions of the tape. The web or tape may be provided in sheet form. The structure comprises "ticks" or discrete linearly oriented spots of material having low specular reflectivity coated on a matte carrier sheet, as by printing, and a layer coated thereon to provide the top layer of the transferred material, which replicates the surface of the carrier sheet and the coated "ticks" or spots.

Abstract: The invention provides a high-solids, low-viscosity, aqueous vehicle particularly adapted for use in coating cellulosic substrates under ambient conditions. The vehicle comprises a water-soluble oil with minute styrene polymer particles uniformly dispersed therein. The water-soluble oil portion comprises the reaction product of a dibasic acid or dibasic anhydride and a drying oil which is neutralized with a nitrogen base. The aqueous vehicle is especially useful in high solids, ink formulations having a high pigment to binder ratio.

The vehicle comprises a water-soluble oil with minute styrene polymer particles uniformly dispersed therein. The water-soluble oil portion comprises the reaction product of a dibasic acid or a dibasic anhydride and a drying oil which is then reacted to provide the water-soluble salt thereof with a nitrogen base. The aqueous vehicle is especially useful in high solids inks and overprint varnishes.

Abstract: The invention provides a fluid plaster composition having desirable flow properties and being capable of setting to a hard material, said composition comprising a calcium sulphate alpha-hemihydrate plaster and an aqueous resin emulsion capable of forming a hard material on removal of water, the relative proportions of the plaster and the resin being such that the plaster takes up the major part of the water in the emulsion when it sets. The resins are preferably homopolymers and copolymers of lower alkyl acrylates and methacrylates, styrene and vinyl acetate. The composition is particularly useful for providing a self-levelling, quick-setting, tough flooring composition which is stable at usual ambient temperatures. Other uses include the casting of art objects such as statuettes.

Abstract: A process for identifying manufactured articles in which a marking agent such as a homo- or copolymer of polymerizable ethylenically unsatured monomers is applied to the articles. Said homo- or copolymer contains at least one group which can be split off to form a low molecular weight compound such as an amine or phenol, which can be converted into dyes, said dyes being used to identify the manufactured articles.

Abstract: A vapor deposited aluminum metallizing film is transformed into a transparent insulating oxide at selective locations at which a film of bismuth or sodium is vapor deposited either beforehand on the substrate or afterward on the aluminum. The oxide forms at only the selected locations to the full depth of the layer and has insulating qualities of interest for electrical components. The use of a pigmented substrate which will show through the transparent oxide areas is useful for providing visible legends, symbols, scales, and reference margins, marks or rasters.

Abstract: A temperature compensated acoustic surface wave device, such as a surface wave delay line is provided in which temperature compensation is provided by the deposition of an interdigital electrode structure on a substrate with an overlay film surface of piezoelectric material of a predetermined thickness. A double substrate arrangement is also disclosed in which the interdigital electrode structure is deposited upon the surface of a non-piezoelectric layer which in turn is placed upon the surface of a piezoelectric substrate.
