Biaxially oriented white polypropylene film for thermal transfer recording and receiving sheet for thermal transfer recording therefrom

Abstract From the Canadian patent

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.
