Abstract:
There is disclosed a print construction comprising: (a)a printing substrate having an image-receiving surface; (b) a receptive layer, at least partially covering said image-receiving surface, and having a particle reception surface distally disposed to said image-receiving surface, said receptive layer optionally having a thickness of at least 1000 nanometer (nm); and (c) a plurality of individual particles adhered to said particle reception surface, and forming a monolayer thereon, the features of which are described herein.
Abstract:
There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface (12) with a monolayer of particles, ii) treating the substrate surface (80) to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate (20), the donor surface (12) returns to the coating station (14) where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.
Abstract:
An apparatus is disclosed for coating a surface that is movable relative to the apparatus with a layer of thermoplastic particles, the particles adhering more strongly to the surface than to one another. The apparatus comprises at least one spray head 1401 for directly or indirectly applying to the surface 12 a fluid stream within which the particles are suspended, a housing 403 surrounding the spray head(s) 1401 and defining an interior plenum 1406 for confining the fluid stream, the housing having a rim 1404 adjacent the surface that is configured to prevent egress of particles from a sealing gap defined between the rim of the housing and the surface to be coated, and a suction source connected to the housing to extract from the plenum 10 the sprayed fluid and particles suspended in the sprayed fluid. In operation, the suction source extracts substantially all particles that are not in direct contact with the surface, so as to leave only a substantially single particle layer adhering to the surface on exiting the apparatus.
Abstract:
The present patent application is related to formation of functional surface modified metal colloids suitable as master batch for direct use in lacquers, paints, coatings and inks. For this the metal colloids are surface modified with organosilsesquioxanes comprising at least one functional group.

Die vorliegende Erfindung betrifft metallische Glanzpigmente, ein Verfahren zu deren Herstellung sowie die Verwendung solcher metallischer Glanzpigmente.
Abstract:
Die Erfindung betrifft beschichtete Metallpigmente, wobei die Metallpigmente einen Metallkern und eine den Metallkern umhüllende Beschichtung umfassen, wobei der Metallkern zu mindestens 60 Gew.-% aus mindestens einem ferromagnetischen Metall besteht, die den Metallkern umhüllende Beschichtung mindestens eine umhüllende Metalloxidschicht und mindestens eine umhüllende chemisch nichtreaktive Kunststoffschicht aufweist, wobei der Gehalt der mindestens einen Metalloxidschicht mindestens 9 Gew.-% und der Gehalt der mindestens einen Kunststoffschicht mindestens 0,4 Gew.-%, jeweils bezogen auf das Gewicht des unbeschichteten Metallpigments, beträgt, wobeidie mindestens eine den Metallkern umhüllende Metalloxidschicht kein Oxidationsprodukt des Metallkerns darstellt. Die Erfindung betrifft ferner ein Verfahren zur Herstellung der Metallpigmente als auch deren Verwendung.
Abstract:
The present invention relates to a method for forming a surface relief microstructure, especially an optically variable image (an optically variable device) on a transparent or translucent substrate and a product obtainable using the method. A further aspect of the invention is the use for the prevention of counterfeit or reproduction of a document of value and a method of forming a coating showing an angle dependent color change.
Abstract:
An elongated steel element adapted for the reinforcement of rubber products is covered with a ternary or quaternary alloy coating of copper-M-zinc. M is one or two metals selected from the group consisting of cobalt, nickel, tin, indium, manganese, iron, bismuth and molybdenum. The copper content inside the coating ranges from 58 weight per cent to 75 weight per cent, the content of said one or two metals inside the coating ranges from 0.5 weight per cent to 10 weight per cent, the remainder is zinc and unavoidable impurities. The one or two metals are present throughout the coating. The phosphorus is present on and/or in the coating in an amount ranging from 0.3 milligram per square meter to 1 milligram per square meter of the coating. The coating further lacks triazole residues. Good results for under cure adhesion have been obtained. Furthermore, a corresponding method for manufacturing such an elongated steel element is disclosed.
