ク防止性に優れている。Detailed Description of the Invention (! - Field of Industrial Application) The present invention relates to a thermal transfer medium using a special surface-roughened film as a support, and can be used for matte transfer or multiple transfers, etc. Moreover, it is excellent in preventing sticking with the thermal head.

とが多く、インキ層とは反対の面から支持体を加熱して
インキを被転写紙に転写する方法が採られてきた。(Prior art and problems to be solved by the invention) Conventionally, thermal transfer media include a smooth polyester film or capacitor paper with a heat-melting ink layer or a heat-sublimating ink layer on one side. A method that is often used is to heat the support from the side opposite to the ink layer and transfer the ink to the paper.

来の支持体は平滑であるためにサーマルヘッドとのスリ
ップ性が悪く、いわゆるスティック現象が発生し易い。In the case of this conventional method, the surface of the transferred ink is smooth, so it has a very glossy power, and it looks good, but on the other hand, it can be difficult to see and look cheap, and it is matte. There is a new requirement for tonal transcription.゛Again. Conventional thermal transfer media are often disposable only once, which poses many problems in terms of cost. On the other hand, since conventional supports are smooth, they have poor slip properties with respect to thermal heads, and tend to cause the so-called stick phenomenon.

Publication No. 01083 describes a method in which a matte layer is provided on a support film and an ink layer is laminated thereon. Further, JP-A-60-101084 describes a method in which a film matted by sandblasting or kneading with inorganic fine particles is used as a support. Further, JP-A-60-13594 describes a method of providing a sublimable ink layer on a support having a roughened surface of 0.5 to 3 .mu.m. All of these require the film to be roughened by a conventional method, resulting in high costs and poor surface roughening accuracy.

Examples include copolymer resins, styrene methyl methacrylate resins, and mixtures thereof.
特にこれらに限定はされない。これらの三つの成分の混
合量は、ポリアリレート樹脂が１〜２０部。There is no particular limitation to these. The mixing amount of these three components is 1 to 20 parts of polyarylate resin.

98 parts, preferably 70 to 92 parts, 1 part of styrenic resin
A suitable range is a combination of 30 parts to 30 parts, preferably 3 to 20 parts, but the ratio of polyarylate resin to styrene resin is extremely unbalanced.
表面の均一な粗面化が実現できず、また機械的特性も不
十分なものしか得られない。Uniform roughening of the surface cannot be achieved, and only insufficient mechanical properties can be obtained.

本願発明方法におけるスチレン系樹脂は、フィルム表面
に小さな凹凸を形成して、ポリアリレート樹脂による大
きな凹凸の間を埋める働きがあり。(Function) The styrene resin in the method of the present invention has the function of forming small irregularities on the film surface and filling in the gaps between the large irregularities caused by the polyarylate resin.

写が可能となる。As a result, a roughened film with uniform unevenness is obtained. Polyarylate resin alone can only produce a film with large irregularities, and when used as a thermal transfer medium,
Although there are problems such as difficulty in fine and uniform transfer, in the film of the present invention, the styrene resin precipitates as aggregated particles smaller than the polyarylate resin, making fine and uniform transfer possible.

添加量は前記した式を満足する範囲が適当であり、この
範囲をはずれると前述の相乗効果が得られず、実用可能
なフィルムは得られない。Further, the mechanical properties are also improved by adding styrene resin. This is presumed to be because the styrene resin acts as a binder between the polyarylate resin and the linear polyester resin. The amount of the styrene resin to be added is appropriately within a range that satisfies the above formula; if it is outside this range, the synergistic effect described above cannot be obtained and a practically usable film cannot be obtained.

表面の凹凸が比較的滑らかであるが、延伸されることに
より凹凸が発現する。延伸倍率は。The film for thermal transfer media of the present invention has relatively smooth surface irregularities in an unstretched state, but as it is stretched, irregularities develop. What is the stretching ratio?

ある。中心面平均粗さはフィルム表面の山の部分の総和
と谷の部分の総和とが等しくなる面を中心面とし、中心
面からの山あるいは谷までの平均距離を表している。The surface roughness of the roughened film is 0.0 as the center surface average roughness.
A suitable value is 5 to 3 mμ, preferably O,OS to 2.5 mμ. The center surface average roughness represents the average distance from the center surface to the peaks or valleys, with the center surface being the surface where the sum of the peaks and the sum of the valleys on the film surface are equal.

合物が適当であるが、特にこれらに限定はされない。The appropriate thickness of the roughened film is 10 to 1.5 μm, preferably 6 to 2.5 μm. Coating of an ink layer onto these roughened films is mainly carried out by a hot melt coating method, a gravure coating method, a reverse coating method, or the like. For heat-melting ink, a mixture of pigments and waxes, polyester resins, ethylene/vinyl acetate resin, etc. is suitable; for heat-sublimation inks, a mixture of sublimable dyes, polyolefin resin, polyester resin, vinyl acetate, etc. is suitable. A mixture of resins having a low melting point or a low softening point, such as a resin based on a polyurethane resin, is suitable, but the present invention is not particularly limited thereto.
