Patent number: 11807731Abstract: A foamed, opacifying element useful as a light-blocking article is prepared with a dry opacifying layer on a substrate. The dry opacifying layer is densified, followed by application of a functional composition formulation to form a functional composition upon drying and curing at a coverage of 0.5-15 g/m2. The functional composition comprises at least: (i) glass particles such as hollow glass particles at a coverage of 0.1-2.2 g/cm2, and can also include any or combination of a (iv) water-soluble or water-dispersible organic polymeric binder that may be crosslinked, thickeners, coating aids having an HLB of at least 5, (ii) lubricants, (iii) tinting materials, and (v) crosslinking agents. Among other properties, the presence of the glass particles provides additional heat absorption for the foamed, opacifying elements that can be formed into light-blocking materials.Type: GrantFiled: March 17, 2020Date of Patent: November 7, 2023Assignee: EASTMAN KODAK COMPANYInventors: Mridula Nair, Lloyd Anthony Lobo, Douglas Edward Garman, James Douglas Shifley

Publication number: 20220282068Abstract: A method to facilitate the reduction of solar radiation impacting Earth proposes the use of a plurality of porous particles that are introduced into Earth's stratosphere at an average distance of at least 10 kilometers above sea level. Each porous particle has a continuous polymeric phase composed of an organic polymer, and discrete pores dispersed within the continuous polymeric phase. Each porous particle has a mode particle size of 2-20 ?m; a coefficient of variance (CV) of no more than 20% compared to the mode particle size; and a porosity of 20%-75%. The discrete pores have an average pore size “d” (nm) that is defined by 0.3?d/??0.8 wherein ? is 400-3,000 nm. Each of the discrete pores of the porous particles is filled with air and optionally a pore stabilizing hydrocolloid that is disposed at the interface of the discrete pore and the continuous polymeric phase.Type: ApplicationFiled: January 28, 2022Publication date: September 8, 2022Inventors: Lloyd Anthony Lobo, Mridula Nair

Patent number: 10696814Abstract: 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 ?m, 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.Type: GrantFiled: June 26, 2018Date of Patent: June 30, 2020Assignee: EASTMAN KODAK COMPANYInventors: Mridula Nair, Lloyd Anthony Lobo, Kevin M.
