PURPOSE:To prevent a sublimable dye from being scattered and lost and contrive a higher printing speed, by placing an image-receiving paper in close contact with a protective layer provided with minute holes, and applying heat thereto to thermally transfer image information. CONSTITUTION:A thermal transfer recording film comprises an ink layer 2 comprising a sublimable dye and a protective layer 3 comprising a thermoplastic resin and having a thickness of 0.1-3mum on a base layer 1. When the protective layer 3 is irradiated with laser light 5 according to image information, a minute hole 7 having a diameter of 0.1-100mum is formed at each irradiated part 4 of the layer 3. When an image-receiving paper 8 is laid on the recording film thus perforated, and heat is applied thereto from the side of the base layer 1 by a thermal head 10, the sublimable dye at only the parts of the ink layer 2 corresponding to the minute holes 7 is sublimed, and is transferred to the paper 8 to form dots 9, whereby recording is achieved. |
