PROBLEM TO BE SOLVED: To manufacture a film to be recorded of superior surface smoothness and proving sufficient image density and resolution. SOLUTION: A void containing polyester film contains a number of voids inside, and its apparent specific gravity is 1.3 or less, the center line average surface roughness is 0.3 mm or less, and an ink acceptive layer is formed at least on one face of the void containing polyester film, and the average light movement distance is 0.15 mm or shorter. |
