がある。[Two Problems to be Solved by the Invention 9] When the main component of the 472-layer binder is wax-based, there are several drawbacks. During thermal transfer printing, a recording sheet is placed on a recording paper, and then a predetermined pressure is applied by a recording head. At this time, due to the pressure, not only the image information that is desired to be recorded but also the portion that is not desired to be recorded is transferred onto the recording paper. There is a drawback that so-called smearing of characters occurs.

った。In addition, recording sheets are often rolled up as a general product, but during long-term storage, ink
A so-called blocking occurred between the back side, that is, the support layer side and the ink layer, and a phenomenon occurred in which all or part of the surfaces of the layers adhered to each other. Especially high temperatures in summer (45-50℃)
), which often occurs in the high-temperature environment in ship holds during export, and is a major drawback of thermal transfer recording sheets.
本発明は、前述の字汚れ、ブロッキングを防止する記録

である。The present invention provides a recording sheet that prevents the above-mentioned character smearing and blocking, and a method for thermal transfer using the recording sheet.

・流出させて被記録紙に熱転写記録するものである。However, although the thermoplastic resin protective layer is effective in preventing character smearing and prolagging, as a thermal transfer ink, it extremely reduces thermal transfer efficiency compared to a wax-based binder. In order to solve this problem, the present invention irradiates the protective layer with a high-energy-density laser beam that corresponds to the image information to make micro holes, and melts and flows out the ink from the micro holes onto the recording paper. It records by thermal transfer.
