Abstract: The object of the present invention is to provide the adsorbent film and the organic EL device comprising the adsorbent film, wherein the water remained within the organic EL device can rapidly adsorb to hold without detaching, the water derived from the circumference can adsorb in a long period, gases as remained or generated in the device, including acidic gases, can adsorb, the life span of the organic EL element can be extended, the workability thereof is superior, it has the sufficient ability of drying, and the moisture adsorbent function can be obtained even in the normal temperature and high-temperature environments. According to the present invention, the adsorbent film and organic EL device comprising the adsorbent film are characterized in that the adsorbent film comprises the resin and the desiccant, it has at least two of moisture adsorbent layers, at least one of the layers contains the chemically-adsorptive desiccant, and the other contains the physically-adsorptive desiccant.

Abstract: A method of manufacturing a reversible heat-sensitive recording medium capable of manufacturing a reversible heat-sensitive recording medium invulnerable toward scratches, etc. even when printing/erasing is repeated under situation where dirt and dust tend to attach to the reversible heat-sensitive recording medium, thus providing increase durability of the reversible heat-sensitive recording medium against repeated printing/erasing. In the method of manufacturing the reversible heat-sensitive recording medium containing a reversible heat-sensitive recording layer and a substrate sheet, a reversible heat-sensitive recording sheet or a reversible heat-sensitive recording transfer sheet having the reversible heat-sensitive recording layer applied to the substrate sheet through welding, after which a protective layer is formed on the reversible heat-sensitive recording layer.
