Abstract: PURPOSE:To obtain the capability of fire retardancy and print data at high speed by allowing the subject film to have the specified number of protrusions of specified height on the surface of film with a specified thickness and adding bromide and/or phosphide. CONSTITUTION:Bromide and/or phosphide are blended or copolymerized, and this blended or polymerized chemical is added to a material. This mixture is melted and extruded and an actually amorphous sheet is oriented at least uniaxially. In this way, polyester film is prepared.
