摘要
PROBLEM TO BE SOLVED: To provide a biaxially stretched white polypropylene film showing excellence in a quality of the film and productivity in which a high sensitivity in case of use for a base material of an acceptance sheet is made to be compatible with the productivity at a high level, and to provide the acceptance sheet for heat-sensitive transfer record using it.;SOLUTION: The biaxially stretched white polypropylene film is obtained by laminating a skin layer (layer B) showing a half crystallization time of 60 seconds or less and surface glossiness of 30 to 145% on at least one surface of a core layer (layer A) having a substantially core-free void. The film has a specific gravity of 0.3 to 0.7 and a β-crystalline activity.;COPYRIGHT: (C)2006,JPO&NCIPI
