Abstract: A solid electrolyte is prepared by dissolving a solvent and an electrolyte salt in a trifunctional polymer and crosslinking it by an irradiation of an active radiation and/or heating, characterized by that said trifunctional polymer is a trifunctional terminal acryloyl-modified alkylene oxide polymer containing a polymer chain expressed by the following general formula (I) as each functional chain; ##STR1## in which R' is a lower alkyl group, R" is hydrogen or methyl group and m or n is 0 or an integer of at least 1 and m+n.gtoreq.35, and the amount of said solvent is 220 to 950 weight % based on said trifunctional terminal acryloyl-modified alkylene oxide polymer.

Abstract: The present invention provides a thermal transfer image-receiving sheet which can form a clear image having a sufficiently high density and excellent in various types of fastness, particularly durability such as light fastness, fingerprint resistance and which is plasticizer resistance according to a thermal transfer printing process wherein use is made of a heat migratable dye. The thermal transfer image-receiving sheet includes a substrate sheet and a dye-receiving layer formed on at least one surface of the substrate sheet, wherein the dye-receiving layer includes a product of a reaction of a polyoxyalkylene polyol with an organic polyisocyanate.
