PURPOSE:To prevent defective carrying by forming a heat-fusing ink layer to the lower surface of a base film and forming a carrying improving layer consisting of a specific polyester copolymer having not less than 3,000mol.wt. to the upper surface of the base film. CONSTITUTION:A heat-fusing ink layer 3 is shaped to the lower surface of a base film 2 through a means such as hot-melt coating by a substance in which a colorant is added to a binder such as carnauba wax. A carrying improving layer 1 consisting of a simple substance or a mixture of alkali metal salt of 8-18C mono or di-alkyl phosphoric ester or consisting of a copolymer having not less than 3,000mol.wt. obtained by condensing and polymerizing one kind or more of aromatic or fatty dicarboxylic acids, one kind or more of 2-4C diols and at least one kind of a polyethylene glycol compound having not less than 2,000mol. wt. is formed on the upper surface of the base film 2. |
