An apparatus is disclosed for coating a surface that is movable relative to the apparatus with a layer of metallic particles or particles having a metal-like appearance and reflectivity, the particles adhering more strongly to the surface than to one another. The apparatus comprises at least one spray head for directly or indirectly applying to the surface a fluid stream within which the particles are suspended, a housing surrounding the spray head(s) and defining an interior plenum for confining the fluid stream, the housing having a rim 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 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.

The present invention relates to method of manufacturing a tamper-proof medium for thermal printing, wherein a liquid treatment composition comprising at least one acid is deposited on a substrate which comprises a thermochromic coating layer comprising at least one halochromic leuco dye.

A first ink composition includes: water; a water-soluble organic solvent; and a color developing agent. The color developing agent includes a pH indicator. The water-soluble organic solvent includes at least one water-soluble organic solvent having a SP value of 16 or less and 11 or more. An amount of the water-soluble organic solvent having a SP value of 16 or less and 11 or more in the first ink composition is 15 wt % or more. A second ink composition includes: water; a water-soluble organic solvent; and a color developing agent. The color developing agent includes a pH indicator. The water-soluble organic solvent includes at least one water-soluble organic solvent having a SP value of 16 or less. An amount of the water-soluble organic solvent having a SP value of 16 or less in the second ink composition is 15 wt % or more. The second ink composition is a water-based ink for ink-jet recording.

Articles of wear having one or more textiles that include a low processing temperature polymeric composition and a high processing temperature polymeric composition, and methods of manufacturing the same are disclosed. The low processing temperature polymeric composition and the high processing temperature polymeric composition can be selectively incorporated into a textile to provide one or more structural properties and/or other advantageous properties to the article. The textile can be thermoformed to impart such structural and/or other advantageous properties to the article of wear. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

The present invention provides an ink jet recording method capable of recording an image having good abrasion resistance by using an aqueous ink and a reaction liquid. In the ink jet recording method, the aqueous ink containing a resin particle and the reaction liquid containing a reactant for aggregating the component in the aqueous ink are ejected from a recording head of the ink jet system and applied onto a recording medium. The reaction liquid contains a compound represented by the general formula (1) (n in the formula represents an integer of 0 to 3). At least one of the aqueous ink and the reaction liquid contains a surfactant having an HLB value of ≤ 15.

There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface 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, the donor surface returns to the coating station 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.

A dye discharge composition exhibiting extended shelf life and/or pot life and high suitability for inkjet printing on dyed substrates, is disclosed. The composition comprises a reducing agent such as, for example, a sulfur-based reducing agent, and a chelating agent, such as a sodium salt of a polyamino carboxylic acid chelating agent. Use of the dye discharge composition in combination with a translucent colored composition and an optional opaque underbase composition, for forming an image on a dyed substrate is also disclosed. Processes for inkjet printing of an image on a dyed surface using the dye discharge composition, kits for use in such processes or an ink formulation containing same are also disclosed.

Apparatus to produce a spatially and temporally uniform heat source is described and this is used to visualize latent fingerprints deposited onto thermal paper by raising the temperature of the paper. Results show an improvement over previous techniques, particularly when fingerprint deposits are aged or the developed fingerprints faint; visualization being enhanced by the use of an LED light source. An investigation of the components in fingerprint sweat likely to affect the solubility and hence colour change of the dye present in the thermal paper has shown that polar protic solvents able to donate a proton are favoured and a polar amino acid found commonly in eccrine fingerprint sweat (lysine) has been shown able to produce the desired colour change. Aged fingerprint deposits on thermal paper from a variety of sources up to four years old have been visualized with this technique.
