摘要： PROBLEM TO BE SOLVED: To provide a thermal transfer film which is excellent in the durability of an obtained thermal transfer print, including the abrasion resistance, light-resistance and forgery preventing properties, and which causes little damage on a transfer object and brings about neither deterioration of the quality of the print, nor a rise of the manufacturing cost. SOLUTION: In the thermal transfer film, a thermal transfer layer having a projecting part partially is formed on one side of a base, at the most distant position from the base, and by using this film, the thermal transfer layer is transferred onto the transfer object. On the occasion, it is possible to form an image beforehand on the object of transfer of the thermal transfer layer by a thermal transfer recording method or the like and to transfer the thermal transfer layer onto the image. In another way, it is possible to form a thermal transfer image by transferring a thermal transfer ink layer onto the thermal transfer layer of the thermal transfer film and to transfer the image together with the thermal transfer layer whereon it is formed. In either way, the image is protected by the thermal transfer layer and the projecting part of the thermal transfer layer transferred onto the transfer object can be distinguished by the reflection of light according to the angle of a glance to an image recording surface. A protective layer and the projecting part can be formed on the transfer object by one transfer.

摘要： PROBLEM TO BE SOLVED: To provide a thermal transfer film which shows the outstanding durability such as wear resistance and light fastness of an obtained imaged matter and good transfer sensitivity and anti-blocking properties during a period when the film is taken up and kept and an imaging method using this film and an imaged matter. SOLUTION: A thermal transfer film 1 has a thermal transfer layer 3 composed mainly of a polyester resin with a glass transition point of 50 to 100 deg.C and a number average molecular weight of 1,000 to 10,000 formed on one of the surface sides of a base 21 and at a farthest position from the base 21. Further, a heat transfer recording medium 7 has a thermal transfer ink layer 8 containing a thermoplastic resin and a coloring agent formed on at least the other surface side of the base 21. In addition, the thermal transfer ink layer 8 of the thermal transfer recording medium 7 or the coloring agent contained in the thermal transfer ink layer 8 is transferred, in an image fashion, to the thermal transfer layer 3 of the thermal transfer film 1 by heating the film 1 and the medium 7 in an image fashion. Consequently, a reverse image is once formed on the thermal transfer film 1 and then the whole thermal transfer layer 3 with a formed image is transferred to an imaged matter 10. Thus it is possible to form an image on the imaged matter 10.
