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： 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.

摘要： A foamed, opacifying element has a substrate with opposing planar surfaces and a foamed opacifying layer disposed on one opposing surface. The foamed opacifying layer contains (a) 0.1-80 weight % of nonporous polymeric particles; (b′) 10-80 weight % of a matrix material derived from a (b) binder material having a glass transition temperature of less than 40° C.; (c) 0.0001-50 weight % of certain additives; (d) less than 5 weight % of water; and (e) at least 0.002 weight % of an opacifying colorant different from all of the (c) additives. Foamable and foamed aqueous compositions can be used to provide these 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.

摘要： Laminate precursors are prepared by applying an aqueous foamed opacifying composition to a non-woven fabric, drying, optionally applying an anti-blocking material to the dried aqueous foamed opacifying composition, and densifying the dry foamed opacifying layer so that it will have a thickness that is at least 20% less than its thickness before densifying. Each laminate precursor is rolled up for immediate or later use to make laminate decorative articles when the unrolled laminate precursor is laminated with back side of a decorative fabric. 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) an opacifying colorant that absorbs electromagnetic radiation having a wavelength of 380-800 nm.

摘要： Laminated light-blocking decorative articles are prepared by applying an aqueous foamed opacifying composition to a non-woven fabric, drying, laminating a decorative 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 desired quantity of a 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.

摘要： 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.
