摘要： An aqueous non-foamed functional composition formulation is disposed on a foamed opacifying layer in light-blocking, foamed opacifying elements. This non-foamed functional composition formulation has 0.5-15% solids and essential (i) and (iv) components and optional (ii), (v), (vi), and (vii) components. The components (i) untreated synthetic silica (fumed silica or precipitated silica) at 0.5-10 weight %; and a (iv) water-soluble or water-dispersible organic polymeric binder having a glass transition temperature (Tg) below 25° C. The weight ratio of the (i) untreated synthetic silica to the (iv) water-soluble or water-dispersible organic polymeric binder is 10:1 to 1:1. The optional components include: a (ii) solid or non-solid lubricant; a (v) crosslinking agent; a (vi) thickener; and a (vii) coating aid. Glass particles can also be present. The presence of the (i) untreated synthetic silica provides improved brightness, e.g. an L* value of at least 80, and uniform coatings in the resulting, foamed opacifying element.

摘要： An aqueous functional composition formulation is used to provide a top layer or pattern in light-blocking opacifying elements. This functional composition formulation has 0.5-15% solids and the essential (i) and (iv) components and any optional (ii), (v), (vi), and (vii) components. The essential components are (i) fumed silica particles at 0.5-10 weight %; and a (iv) water-soluble or water-dispersible organic polymeric binder having a glass transition temperature (Tg) below 25° C. The weight ratio of the (i) fumed silica particles to the (iv) water-soluble or water-dispersible organic polymeric binder is 10:1 to 1:5. The optional components include: a (ii) solid or non-solid lubricant; a (v) crosslinking agent; a (vi) thickener; and a (vii) coating aid. Glass particles can also be present. The presence of the (i) fumed silica provides improved brightness, e.g. an L* value of at least 80, and uniform coatings in the opacifying element.

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： A foamed, opacifying element useful as a light-blocking article has a substrate; an opacifying layer disposed on the substrate, and a functional composition disposed over the opacifying layer. The functional composition comprises: (i) glass particles such as hollow glass particles. The presence of the glass particles provides additional heat absorption for the foamed, opacifying elements that can be formed into light-blocking materials.

摘要： Foamed, opacifying elements are prepared using a foamable aqueous composition containing porous particles and an opacifying colorant. This composition is aerated, disposed onto a substrate, and dried. The dry foamed composition is densified, and cured in either order. At some point after the drying feature, a functional composition is disposed onto either the dry foamed composition or the opacifying layer, and dried. This functional composition has either or both of: (i) inorganic or organic spacer particles having a mode particle size of 1 to 100 μm, and which inorganic or organic spacer particles resist melt flow at a pressure of up to and including 100 psi (689.5 kPa) and a temperature of up to and including 220° C.; and (iii) a tinting material comprising a pigment, dye, or a combination thereof. The (i) inorganic or organic spacer particles and the (iii) tinting material are different materials.

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.

Each porous particle includes a continuous polymeric phase and discrete pores; a mode particle size of 2-50 μm; and a porosity of 20-70 volume %. 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 Y tristimulus value. The foamed aqueous composition has a foam density of 0.1-0.5 g/cm3.
