摘要： A method is designed to prepare foamed, opacifying elements each having a target light blocking value (LBVT) of at least 3, using a textile fabric substrate with a light blocking value (LBVS). The LBVT-S difference is calculated; a foamable aqueous composition is chosen; a dry coating weight for the foamable aqueous composition (when foamed) is determined to form a single dry opacifying layer that is foamed, dried, and densified to provide a dry thickness at least 20% less than the original dry thickness. The single dry opacifying layer a has light blocking value that is equal to LBVT-S, ±15%. The desired foamable aqueous composition can be chosen from a set of similar compositions to achieve the desired LBVT with the noted textile fabric substrate using suitable mathematical formula relating dry coating weight to light blocking value and a suitable data processor.

摘要： A foamed, opacifying element is prepared to have a light-blocking value (LBV) of at least 4. A method is carried out in a specific order with a unique series of steps including: providing a unique foamable aqueous composition; aerating that foamable aqueous composition to a foam density of at least 0.1-0.5 g/cm3; disposing the foamed aqueous composition onto a surface of a porous substrate; drying the foamed aqueous composition without substantial curing of the binder material therein, to provide a dry foamed composition on the surface, without substantial curing; densifying the dry foamed composition to provide a dry opacifying layer in a foamed, opacifying element; and curing the dry opacifying layer in the foamed, opacifying element.

摘要： Articles can be formed with either a dried layer or a dried pattern of a non-aqueous photocurable composition on one or both sides of a substrate. This composition includes a photocurable component and dispersed carbon-coated metal particles present in an amount of at least 10 weight % based on the total weight of the non-aqueous photocurable composition. The dispersed carbon-coated metal particles have a median diameter of less than 0.6 μm, and a particle dispersing agent that has a weight average molecular weight (Mw) of at least 2,000 and up to and including 10,000 and comprises nitrogen-containing units, the median diameter being determined using a dynamic light scattering method. Such articles can be used for various purposes including the formation of electrically-conductive grids, and can be incorporated into various devices including those having touch screen displays.

摘要： A non-aqueous photocurable composition contains dispersed carbon-coated metal particles in an amount of at least 10 weight %, and the dispersed carbon-coated metal particles have a median diameter of less than 0.6 μm. These particles are dispersed with a particle dispersing agent that has a weight average molecular weight (Mw) of at least 2,000 and up to and including 100,000 and comprises nitrogen-containing units. Such compositions include an organic diluent as well as suitable photocurable components that can be used for example in acid-catalyzed or free radical chemistries. When the non-aqueous photocurable composition contains up to and including 25 weight % of the dispersed carbon-coated metal particles, it exhibits no visual settling when subjected to a settling test of at least 24 hours at 20° C. The non-aqueous photocurable compositions can be used to provide photocured metallic patterns for various devices that have a touch screen display.
