摘要： An opacifying article has 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.

The continuous polymeric phase Tg is >80° C. and has a polymer viscosity of 80-500 centipoises at an ethyl acetate shear rate of 100 sec−1 at a concentration of 20 weight % at 25° C. The dry opacifying element light blocking value is at least 4 and has a luminous reflectance >40% as measured by the color space Y tristimulus value.

摘要： A foamable aqueous composition can be used to form foamed, opacifying elements with one or more dry foamed layers. These compositions generally contain: (a) 0.5 to 20 weight % of porous particles comprising a continuous polymeric phase and discrete pores dispersed within the continuous polymeric phase. The porous particles have a mode particle size of 2 to 50 μm; (b) at least 20 weight % of a binder material; (c) 0.1 to 30 weight % of a combination of various additives including dispersants, plasticizers, inorganic or organic pigments and dyes, flame retardants, biocides, fungicides, optical brighteners, tinting colorants, metal flakes, and inorganic or organic fillers; (d) water; and (e) at least 0.001 weight % of an opacifying colorant different from (c). The foamable aqueous composition is suitably aerated, disposed on a porous substrate, dried, and crushed on the porous substrate to form a foamed, opacifying element.

摘要： Composite materials such as composite particles have a solid non-elastomeric continuous phase made of an organic polymer having a glass transition temperature of at least 25° C. Dispersed within this solid non-elastomeric continuous phase are many multi-compartment porous chemically crosslinked elastomeric particles that have a mode particle size of at least 1 μm and up to and including 10 μm. The composite particles can be used as toner particles in electrophotographic imaging methods to provide fused toner images and especially stacked fused toner images.

摘要： Patterned light-blocking elements are prepared using a method having operations A) through F). Such method includes providing an ii) embossed and densified foamed opacifying layer on the back side of a i) fabric and a iii) non-foamed function composition on the ii) embossed and densified foamed opacifying layer. Embossing can be carried out using a specific i) fabric having a prefabricated visible relief pattern on its face side. During embossing and densification, this prefabricated visible relief pattern self-embosses the ii) embossed and densified foamed opacifying layer, thus providing a visible relief pattern in that layer that can be viewed from the face side of the patterned light-blocking element when appropriately backlit as a transmissive display in a darkened environment. Such elements can be used as window treatments as well as decorative fabrics in various environments.

摘要： Patterned light-blocking elements are prepared using a method having operations A′) through F′), or a method having operations A″) through G″). Such methods include providing an ii) embossed and densified foamed opacifying layer on the back side of a i) fabric and a iii) non-foamed function composition on the ii) embossed and densified foamed opacifying layer. Embossing can be carried out using self-embossing or any suitable embossing means including a continuous embossing belt or web or an embossing roller or sleeve. The embossing operation provides a visible relief pattern in the ii) embossed and densified foamed opacifying layer that can be viewed from the face side of the patterned light-blocking element when appropriately backlit as a transmissive display in a darkened environment. Such elements can be used as window treatments as well as decorative fabrics in various environments.

摘要： Foamable and foamed aqueous compositions can be used to provide foamed, opacifying elements for use as light-blocking window shades, curtains, or other materials. These light-blocking articles can also have a printable outer surface that accepts ink for making printed images that are not observable from the opposite surface. Such foamable and foamed aqueous compositions comprise nonporous polymeric particles.
