Abstract: Anti-fog compositions comprising a primary film having opposing major planar surfaces and a central coplanar region, and processes for making such anti-fog compositions. The central coplanar region is disposed between the opposing major planar surfaces. The primary film comprises cellulose acetate, plasticizer, and an anti-blocking agent. The anti-blocking agent has an average particle size ranging from 0.02 microns to 6 microns. The cellulose acetate has a degree of substitution that increases from the opposing major planar surfaces toward the central coplanar region or that is substantially constant throughout the thickness of the composition. The composition is formed by saponifying a precursor film to improve hydrophilicity.
Abstract: Hot melt and pressure-sensitive adhesives may comprise highly-plasticized cellulose esters, e.g., a cellulose ester and a plasticizer, the plasticizer included in an amount of about 30% to about 60% by weight of the cellulose ester. A highly-plasticized cellulose ester adhesive that is non-tacky at room temperature may be utilized by heating an adhesive to yield an adhesive melt, the adhesive comprising a cellulose ester and a plasticizer, the plasticizer included in an amount of about 15% to about 60% by weight of the adhesive; applying the adhesive melt to a first surface; and adhering a second surface to the first surface with the adhesive.

Abstract: Cellulose diester films that include a cellulose diester; a plasticizer; a colorant; and an opacity additive may be useful for playing cards. In some instances, forming cellulose diester films may include preparing a dope that comprises a cellulose diester, a plasticizer, and a solvent; introducing a colorant and an opacity additive into the dope to yield a casting dope; and casting the casting dope into a cellulose diester film. Playing cards may then be produced by methods including, for example, cutting the cellulose diester film and printing on the cellulose diester film.

A highly-plasticized cellulose ester adhesive may be utilized in a sheet form by disposing the adhesive sheet between a first surface and a second surface; and heating the adhesive sheet so as to adhere the first surface to the second surface.

Abstract: Protective films for plasma displays, spectacles or especially polarizers (for example based on cellulose triacetate) including particular plasticizers as a constituent of imaging devices of liquid-crystal type or of spectacles, their production and use, and liquid-crystal display devices and film polarizers producible with them, and also further subject matter of the invention specified in the description, are particularly suitable for thin films and have advantageous properties, for example low water vapor permeability. The plasticizers used are one or more of the formula (I) in which the radicals are each as defined in the rest of the disclosure and are branched-chain alkyl radicals having 9 or 10 carbon atoms, and advantageously one or more further plasticizers.
