Abstract: An opacifying article can be made using a (i) fabric having a face side and a back side and an (ii) opacifying element having a substrate that has first and second opposing surfaces; and a dry opacifying layer that has an inner surface and an outer surface. The dry opacifying layer is disposed with its inner surface in contact with the first opposing surface of the substrate. The dry opacifying layer has (a) 40-90 weight % of porous particles, each having a continuous polymeric phase and discrete pores dispersed within the continuous polymeric phase. The porous particles have a mode particle size of 2-50 μm and a porosity of 20-70 volume %. The dry opacifying layer also contains (b) 10-60 weight % of a binder material. The (ii) opacifying element is laminated to the back side of the fabric to provide the opacifying article.

Abstract: Inkjet printing is carried out to provide monochrome or polychrome inkjet-printed images. An ink-receptive medium is provided with a substrate with an aqueous-based ink-receptive layer disposed thereon. The aqueous-based ink-receptive layer has: (a) one or more water-soluble salts of a multivalent metal cation in an amount of 0.6-49 weight %; (b) one or both of a polyvinyl alcohol and a polyvinyl amine (or a copolymer of a vinyl alcohol and vinyl amine) in a total amount of 0.5-30 weight %; and optionally, (c) a crosslinking agent and (d) silica particles. One or more aqueous pigment-based inks are inkjet printed onto this aqueous-based ink-receptive layer, each ink comprising: a) one or more anionically-stabilized pigment colorants; b) one or more water-miscible humectants that are present in a total amount of 1-20 weight % and each having a carbon atom to oxygen atom ratio of at least 1.0:1.0 and only two hydroxy groups.

Abstract: IR-sensitive lithographic printing plate precursors provide a stable print-out image using a unique IR radiation-sensitive composition. This IR radiation-sensitive composition includes: a) free radically polymerizable component; an b) IR radiation absorber; c) an initiator composition; a d) borate compound; and a e) compound capable of forming a colored boronic complex during or after exposure of the infrared radiation-sensitive image-recording layer to infrared radiation. The resulting print-out image exhibits an excellent color contrast between the exposed and non-exposed regions. After IR imaging, these precursors can be developed off-press or on-press.

Abstract: An electrode film includes a first electrode pattern having a first set of parallel conductive electrodes and a second electrode pattern having a second set of parallel conductive electrodes disposed on a first surface of a transparent film, wherein elements of the first electrode pattern do not cross over elements of the second electrode pattern. A third electrode pattern having a third set of parallel conductive electrodes is disposed on a second surface of the transparent film, wherein the first, second and third sets of parallel conductive electrodes are arranged in an interlaced pattern. The electrode patterns are configured to be connected to respective power sources of electrical power supplying respective waveforms to generate a time-varying electric field pattern above a surface of the electrode film.

Abstract: A light-blocking article is designed to be lightweight but effective to block most incident actinic radiation and can be designed into fabrics, curtains, and other materials. Such an article has an opacifying layer that is capable of blocking predetermined electromagnetic radiation. The article contains (a) porous particles comprising a continuous polymeric binder and pores within the continuous polymeric binder, the porous particles having a glass transition temperature of at least 25° C. and a mode particle size of at least 2 μm and up to and including 50 μm. The article also contains an opacifying colorant that absorbs the predetermined electromagnetic radiation (such as within 400 nm to 700 nm), in an amount of at least 0.001 weight % based on the total dry weight of the opacifying layer, and a matrix polymer in which the porous particles and opacifying colorant are dispersed.

Abstract: Laminated light-blocking decorative articles are prepared by applying an aqueous foamed opacifying composition to a decorative fabric, drying, laminating a non-woven fabric to the resulting dry foamed opacifying layer, and densifying that layer to have a thickness that is at least 20% less than before densifying. This operation can be carried out so that non-woven fabric, decorative fabric, and aqueous foamed opacifying composition are supplied in a single-pass, in-line operation to make any quantity of laminated light-blocking decorative article. The applied aqueous foamed opacifying composition has 35%-70% solids and a foam density of 0.1-0.5 g/cm3. It is composed of (a) porous particles, (b) a binder material, (c) two or more additives comprising at least one foaming surfactant and at least one foam stabilizer, (d) an aqueous medium, and (e) at least 0.0001 weight % of an opacifying colorant that absorbs electromagnetic radiation having a wavelength of 380-800 nm.

Abstract: IR-sensitive lithographic printing plate precursors provide a high contrast and stable printout image using an IR radiation-sensitive composition. This composition includes: a free radically polymerizable component, an IR absorber, an initiator composition, color-forming compound(s) such as a specific leuco dye, and compound(s) represented by the following Structure (P): wherein X is —O—, —S—, —NH—, or —CH2—, Y is >N— or >CH—, R1 is hydrogen or an alkyl, R2 and R3 are independently halo, thioalkyl, thiophenyl, alkoxy, phenoxy, alkyl, phenyl, thioacetyl, or acetyl, and m and n are independently 0 or an integer of 1 to 4. The printout image exhibits a color contrast between the exposed and non-exposed regions of a ΔE greater than 8. A ΔE of at least 5 is maintained between the exposed and the non-exposed regions with exposure to white light for at least one hour. These precursors, when IR-exposed, can be developed on-press.

Abstract: A continuous inkjet printer includes a linear printhead having a cross-track printhead width that is wider than a cross-track image width. The linear printhead is characterized to determine an image quality level as a function of cross-track position. A segment of the linear printhead is designated wherein the image quality level within the designated segment of the linear printhead is acceptable. A translation mechanism is used to translate the linear printhead relative to the receiver medium such that the designated segment of the linear printhead is aligned with a region on the receiver medium where the image content is to be printed, and the image content is printed on the receiver medium using the designated segment of the linear printhead.
