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/cm.sup.3. 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.

A shielding device for shielding against weather influences that includes a textile sheet material which is stretched two-dimensionally or can be rolled out and which forms a shield against weather influences, in particular, against solar radiation and/or rain. The textile material has warp threads and weft threads connected together in a lattice-like manner so as to form a fabric. A foam layer which has foam pores that are separated from one another by solid foam walls is applied onto the textile sheet material on at least one side of the textile sheet material.

The present invention relates to multi-layered composite structures and to methods for the preparation thereof. The present multi-layered composite structures are light weight and capable of high load bearing making the present multi-layered composite structures especially suitable to be used as load bearing structures in, for example, automotive. Specifically, the present invention relates to methods comprising the steps of a) providing a mould for said multi-layered composite structure; b) layering said mould with two or more layers forming the outer surface of said multi-layered composite; c) filling said layered mould with a mixture comprised of non-expanded heat-expandable microspheres and closing said mould; and d) subjecting said closed mould to a temperature of 80° C. to 140° C. during 1 to 230 minutes thereby providing a relative pressure in said closed mould of 0.1 to 20 bar through expansion of said heat-expandable microspheres thereby forming a multi-layered composite structure in said mould with a foam enforced inner core and a multi-layered outer surface; and e) separating the multi-layered composite structure from said mould.

Provided is a light weight and remarkably flexible sheet-shaped radio wave absorber having excellent radio wave absorbing capacity in milliwave band frequencies. The invention is a milliwave band radio wave absorption sheet comprising a radio wave reflection layer (A), a radio wave absorption layer (B) disposed above the layer (A) so as to be parallel thereto, and a protective layer (C) disposed above the layer (B) so as to be parallel thereto. The layer (B) has, at a frequency of 79 GHz, a dielectric constant, wherein the real part is 10 to 20 and the absolute value of the imaginary part is 4 to 10. The layer (B) has a film thickness of 200 to 400 μm. The absolute value of the imaginary part/real part from the dielectric constant is within a range of 0.30 to 0.60. The layer (C) has, at a frequency of 79 GHz, a dielectric constant, wherein the real part is 1.5 to 8.0 and the absolute value of the imaginary part is less than 1.0, and has a film thickness of 50 to 200 μm. In the milliwave band radio wave absorption sheet, the optical reflectance at an incident angle of 60° is 50% or greater, and the optical reflectance at an incident angle of 20° is 25% or greater. In addition, the invention provides a milliwave band radio wave absorption method using the radio wave absorption sheet, and a radio wave damage prevention method involving the installation of the radio wave absorption sheet.

Various embodiments disclosed relate to a composite shingle. The composite shingle includes a particle layer and a polyketone layer proximate to the particle layer.

A multi-layered, multi-spectral target for rifles. The multi-layered target comprises a first layer printed rifle target having at least one target position on a first surface and a light reflective film surmounted on a second surface of the first layer printed rifle target. There is a cutout silhouette layer surmounted on the light-reflective film wherein the light reflective film shows through the cutout silhouette.

Inflatable membranes may include a pattern layer, a fluorescent layer, and a window, the pattern layer comprising an inner surface and an outer surface, the pattern layer comprising a pattern on the inner surface of the pattern layer, and at least a portion of the pattern layer formed by a transferrable material transferred from a casting plate to the inner surface. The fluorescent layer may include an inner surface and an outer surface, the inner surface of the fluorescent layer abutting the outer surface of the pattern layer and comprising a fluorescent material which, upon receiving of light, causes the fluorescent material to emit fluorescent light and causing the pattern to be detectable by a detector. The window may include a transparent material that spans an aperture formed in a distal end of the inflatable membrane.

A two-color molding die includes: a fixed primary die; a fixed secondary die; and a movable die. The fixed primary die includes a first concave portion. The movable die includes a second concave portion facing the first concave portion, and a core pin that protrudes from a base end surface of the second concave portion toward a base end surface of the first concave portion to form a tubular primary molding cavity between the core pin and the first concave portion and the second concave portion. The fixed secondary die includes a third concave portion configured to form a concave secondary molding cavity.

A single-layer or multilayer film formed from one or more polymeric materials has CIE colour values a* and b* such that −7≤a*≤0, −15≤b*≤0 and an optical transmission T such that 60%≤T≤95%. The inventive, transparent films provide discoloration compensation that alleviates yellowing caused by UV light.
