A sealing member according to the present invention is a sealing member against a synthetic oil containing an ester-type additive, and includes 95.0% by mass or more and 99.5% by mass or less of a para-phenylene diisocyanate-based polyurethane and 0.5% by mass or more and 5% by mass or less of a same compound as the ester-based additive. The sealing member according to the present invention has a smaller friction coefficient and more excellent deformability than conventional sealing members and that can inhibit swelling caused by a synthetic oil.

The present invention is a sealing material composition comprising a moisture absorbent, and a sealing resin having a weight average molecular weight of 50,000 to 1,000,000, the moisture absorbent comprising a compound that comprises a repeating unit represented by a formula (1), and

##STR00001## a sealing sheet, and an electronic device member, and an electronic device.

The sealing material composition according to the present invention makes it possible to easily produce a sealing sheet that exhibits excellent transparency, an excellent water vapor barrier capability, and high adhesion, and the sealing sheet according to the present invention exhibits excellent transparency, an excellent water vapor barrier capability, and high adhesion, and may suitably be used to seal an organic EL device and the like, and the electronic device member and the electronic device according to the present invention rarely deteriorate, and exhibit excellent long-term reliability.

Methods of temporarily enhancing the luster and/or brilliance of a piece of jewelry, a gem stone, or a piece of jewelry including a gem stone including applying a non-aqueous composition to the piece of jewelry, the gem stone, or the piece of jewelry including a gem stone.

Low hydroxyl value dibenzoate plasticizer for use in a reactive polyurethane composition, including but not limited to thermoplastic and thermoset polyurethanes, wherein the plasticizer is particularly useful in TPU's, a reactive polyurethane adhesive or sealant, or a tastable polyurethane article and achieves comparable or improved properties, including without limitation compatibility, color, exudation, optical properties, MVTR, hardness, tensile strength, tear strength, rebound, compression set, and solvent swell, when compared with that achieved with traditional plasticizers, including other benzoate esters, used in polyurethane compositions.

A wide temperature water borne sealant that can be applied at low temperatures. The sealant can be a latex sealant composition including at least one latex polymer, at least one freeze thaw stabilizer, and at least one peptone or at least one additive derived from a peptone. The latex polymer can be an acrylic latex polymer with a Glass Transition Temperature (Tg) of 0° C. or less. The peptone can be enzymatic hydrolysate. The sealant can remain pliable at low temperatures making it ideal for applications that require flexibility at low temperatures its' rheology and viscosity are such that it can be applied at temperatures below 0° C. The low Tg latex assures that the sealant will remain permanently flexible and non-tacky when cured, and the peptone provides the sealant with the means to prevent the water from freezing down to approximately −20° C.

Compositions for enhancing the luster and/or brilliance of jewelry and/or gem stones comprising a non-aqueous carrier and optionally additives and/or fragrances, and methods for making and using same.
