Abstract: With white films or micro-porous films for thermal transfer recording in the prior art involving .beta.-crystal transitions, production of the film and receiving sheet were not compatible, at a high level, with the sensitivity of the receiving sheet. The present invention relates to a biaxially oriented white film for thermal transfer recording which has low specific gravity required as a thermal transfer film, high whiteness and cushion factor, and is excellent in crease resistance, and has a high--level compatibility between high sensitivity and productivity when used as a substrate of a receiving sheet, and a receiving sheet for thermal transfer recording using the same.

Abstract: A biaxially oriented polypropylene film exhibiting a high rigidity in the machine direction can be produced according to a general lengthwise-widthwise sequential biaxial stretching process either by specifying the additive contained in the film, the melt-tensile strength (MS) and melt flow rate (MFR) of the polypropylene as determined at 230 °C, or the Trouton ratio of the polypropylene or by making specified longitudinal fibrils present in the film.
