BIAXIALLY ORIENTED POLYPROPYLENE FILM FOR THERMAL TRANSFER RECORDING AND ACCEPTING SHEET FOR THERMAL TRANSFER RECORDING MADE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a biaxially oriented polypropylene film with a low specific gravity, a high cushionability, a high optical density OD and an improved anti-creasing property on bending.

SOLUTION: A laminated film with a density of 0.5-0.85, an optical density OD of 0.4 or more and a cushion ratio of 10% or more comprises (A) a cell containing polypropylene film layer containing an amorphous resin with a glass transition temperature(Tg) of 100°C or more and β crystal(or crystalloid) ratio of 20% or more and (B) a layer containing non-nucleous cells.
