数回使用型感熱転写リボンに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multi-use type thermal transfer ribbon used in a thermal transfer type hard copy printer, and more specifically, to a thermal transfer ribbon that can be used repeatedly at the same location. This invention relates to a thermal transfer ribbon that can be used multiple times.

じみ出させるものなどが提案されている。[Prior Art and Problems to be Solved by the Invention] Conventional thermal transfer ribbons of this type that can be used multiple times include those in which a non-transferable sponge-like resin layer is impregnated with thermal transfer ink; A pigment having cohesive force is dispersed in a heat-sensitive transfer ink, and the heat-sensitive transfer ink oozes out from a stone wall layer composed of the agglomerated pigment, and a porous powder is bonded with a binder. A method has been proposed in which the thermal transfer ink existing within the powder and between the powder gradually oozes out.

け不鮮明になる欠点がある。また、転写インクのうち毛
細管現象によりにじみ出さないものも存在し、残存して
しまうという欠点かある。However, in any of the above proposals, a large amount of non-transferable substance must be present in the ink layer, and the thickness of the ink layer increases compared to the amount of transfer ink, resulting in a difference in the printed image. However, there is a drawback that it becomes unclear. Furthermore, there are some transfer inks that do not ooze out due to capillary action and remain, which is a drawback.

には、非転写であるはずの部材が誤って転写してしまい
、印像濃度にむらが生じたり再度の使用時に欠けが生じ
たりすることも生じやすいという欠点がある。In other words, there is a problem that the amount of ink that can be effectively used is small compared to the thickness of the transfer ink holding layer, which has a large effect on the sharpness of the printed image, and it is difficult to repeatedly print clear images. There are disadvantages in that a member that is supposed to be erroneously transferred may be erroneously transferred, resulting in uneven printed image density or chipping when used again.

する多数回使用型感熱転写リボンに関する。[Means for Solving the Problems] The present invention provides a thermal transfer ink layer that is melted or softened by heating with a heating head and transferred to a receptor on one side of a base material, and that the thermal transfer ink layer is formed in the thickness direction. A thermal transfer ribbon for partial transfer at 190°C, wherein the thermal transfer ink layer has a melt index of 4X102 to 2.5X at 190°C.
The present invention relates to a multi-use thermal transfer ribbon characterized in that it contains 3 x 10 to 6 x 10 volume % of non-thermoplastic powder in a non-agglomerated state.
前記においてメルトインデックスはＡＳＴＭ・Ｄ１２３
８に準拠して測定したものである。In the above, the melt index is ASTM D123.
This was measured in accordance with 8.
［作用および実施例］

クか転写してしまい、残るのは基材のみとなるのである
。[Operations and Examples] The multi-use thermal transfer ribbon of the present invention has the above-mentioned configuration. With this configuration, the ink layer is gradually transferred, and eventually all of the The ink is transferred and all that remains is the base material.
したがって、前記したごとき従来技術が有する欠点は発
生せず、鮮明な印像がえられながらも従来に比べて多数
の繰り返し回数を確保しうるのである。Therefore, the disadvantages of the prior art as described above do not occur, and while a clear printed image can be obtained, a greater number of repetitions can be ensured than in the prior art.
このような現象を推察するに、インク層中に含有されて

繰り返しによってもほぼ安定している理由は定かではな
い。Inferring this phenomenon, stress concentration points occur around the non-agglomerated powder contained in the ink layer, and the vehicle is maintained at an extremely high viscosity and strongly fixed to the base material. It is thought that the ink layer is cut at an intermediate point in its thickness due to the presence of the ink layer, but it is not clear why the thickness of the transfer remains almost stable even after repeated transfers.
ちなみに、前記インク層のメルトインデックスを１９０
℃で３ ｘ １０３ｇ／１０分程度にしたばあいには、
−度にほとんど全量のインクが転写してしまう結果をえ
ている。By the way, the melt index of the ink layer is 190.
When it is about 3 x 103g/10 minutes at ℃,
- The result is that almost the entire amount of ink is transferred at one time.

る。Further, when the melt index of the ink layer is set to about 3 x 102 g/10 minutes at 190°C, the printing density is too low from the first time, making it impossible to obtain a clear printing image. Furthermore, if the amount of the powder is about 20% by volume, a large amount of ink will be transferred at once, and the density of the second and subsequent impressions will be extremely low, making it impossible to use repeatedly. %, almost no transfer occurs.
なお、粉体の含有量が増加するにつれてメルトインデッ
クスの数値を大きくする（つまり、柔らかくする）のが
好適である。Note that it is preferable to increase the value of the melt index (that is, to make it softer) as the content of the powder increases.
つぎに、本発明の構成を具体的に説明する。Next, the configuration of the present invention will be specifically explained.
インク層を構成するベヒクルは、その主成分として熱可

のものを１種または２種以上混合して用いるのがよい。The vehicle constituting the ink layer may use a thermoplastic resin as its main component, and its melt index at 190°C is approximately 4 x 102 to 2.5 x 103 g/10 minutes, preferably 8 x 102 to 1.5. It is preferable to use one kind or a mixture of two or more kinds of about 103.
また、前記メルトインデックスの範囲外の樹脂でも、混
