BIAXIALLY ORIENTED WHITE POLYPROPYLENE FILM, REFLECTIVE PLATE, AND RECEIVING SHEET FOR THERMAL TRANSFER RECORDING

摘要

A biaxially oriented white polypropylene film containing a core layer (layer A) and a skin layer (layer B), said layer B is laminated at least on one surface of said layer A, wherein said layer A contains a polypropylene resin having ²-crystal activity and 1 to 20 mass % particle (a) having an average dispersed diameter of 60 to 400 nm, and wherein, said layer B contains a polypropylene resin and 0.05 to 5 mass % particle (b) of an average dispersed diameter of 1 to 4 µm. The present invention provides a biaxially oriented white polypropylene film excellent in film quality and productivity and capable of making sensitivity and productivity compatible in a high level when used as a base for a receiving sheet, and a receiving sheet for thermal transfer recording made thereof.
