PROBLEM TO BE SOLVED: To provide a mark transfer technology utilizing a coat film transfer technology as to various marks composed of characters, symbols, graphics or combination thereof. SOLUTION: A mark transfer tape T has a transfer mark layer 16 peelably adhered and held on a base tape 15. The transfer mark layer 16 is formed by integrally laminating a pressure-sensitive adhesive layer 19, a mark array layer 18, and a surface forming layer 17, in which the adhesive force PA of the pressure-sensitive adhesive layer 19 on a transfer area, the rupture strength PB of the transfer mark layer 16, the adhesive force PC of the transfer mark layer 16 and the base tape 15, and the adhesive force PD of the pressure-sensitive adhesive layer 19 and the base tape 15 are set in the relation of PA≥PB≥PC≥PD, and the elongation rate of the transfer mark layer 16 is set in a visual deformation allowable range of the transfer mark M at the time of its pressing and transferring. Therefore, the transfer mark during the transfer is transferred without visual deformation, crack or cut, so that a favorable transfer property is assured. COPYRIGHT: (C)2004,JPO |
