Dye-image receiving element for use according to thermal dye sublimation transfer comprising a support having thereon a dye-image receiving layer containing a (co)polyester comprising condensation residues of one or more diols and one or more dicarboxylic acids and further comprising condensation residues of one or more hydroxy-carboxylic acids containing a long chain alkyl or alkylene group having at least 8 carbon atoms.
Disclosed is a refrigerator oil composition comprising at least one base oil selected from mineral oils and synthetic oils, and at least one hydroxy-fatty acid derivative selected from (A) hydroxy-fatty acids or their condensates, (B) metal salts or amine salts of hydroxy-fatty acids or their condensates, and (C) esters of hydroxy-fatty acids. The composition has an excellent lubricating property, while specifically improving the lubricity between aluminium materials and steel materials. This is effective for preventing such materials from being seized and worn, and is suitable as a lubricating oil in refrigerators using hydrogen-containing Flon refrigerants, such as R134a, that do not cause environmental pollution.
