ABSTRACT:
A recording medium for sublimation type heat-sensitive transfer recording process, in which an image receiving layer comprising a resin composition containing a dyeable resin and at least one phosphite antioxidant shown in Formulas (1), (2), or (3) is formed on a substrate surface. This recording medium for sublimation type heat-sensitive recording methods has extremely superior light resistance, and the image recorded on this recording medium suffers little fade out or discoloration as a result of exposure to light, so that this recording medium is expected to contribute greatly to the spread of video printers and the like. ##STR1## (In Formula (1), R.sub.1 and R.sub.2 represent H or an alkyl group having a number of carbon atoms within a range of 1-20, R.sub.3 and R.sub.4 represent alkyl groups having a number of carbon atoms within a range of 1-20, X represents H or an atomic group having 1-10 carbon atoms as a main skeleton thereof, and n has a value of 1, 2, 3, or 4.) ##STR2## (In Formula (2), R.sub.5 and R.sub.6 represent H or an alkyl group having a number of carbon atoms within a range of 1-20, R.sub.7 represents an alkyl group having a number of carbon atoms within a range of 1-20, Y represents H or an atomic group having 1-10 carbon atoms as a main skeleton thereof, and n has a value of 1, 2, 3, or 4.) ##STR3## (In Formula (3), RS, R.sub.9, R.sub.10, and R.sub.11 represent H or an alkyl group having a number of carbon atoms within a range of 1-20, Z represents H or an atomic group having 1-10 carbon atoms as a main skeleton thereof, and n has a value of 1, 2, 3, or 4.)
