    • 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.)
    • 一种用于升华型热敏转印记录方法的记录介质,其中形成包含式(1),(2)或(3)所示的包含可染树脂和至少一种亚磷酸酯抗氧化剂的树脂组合物的图像接收层 在基板表面上。 用于升华型热敏记录方法的记录介质具有非常优异的耐光性,并且记录在该记录介质上的图像由于曝光而几乎不会淡出或变色,使得该记录介质有望大大有助于 视频打印机的传播等。 (1)(式(1)中,R 1和R 2表示H或碳原子数在1〜20的范围内的烷基,R 3和R 4表示碳原子数为1〜 范围1-20,X表示H或具有1-10个碳原子的原子团作为其主要骨架,n的值为1,2,3或4.)(2)式 (2)中,R5和R6表示H或碳原子数为1-20的烷基,R7表示碳原子数为1-20的烷基,Y表示H或 (3)(式(3)中,RS,R9,R10,R10,R10, R11表示H或碳原子数在1-20的范围内的烷基,Z表示H或碳原子数为1〜10的原子团为主要骨架,n为1,2 ,3或4。
