Abstract
Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、通電熱転写記録媒体の製造方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for manufacturing an electrically conductive thermal transfer recording medium.
通電熱転写記録方式とは、ヘッド基板上に設けられた抵
抗体を発熱させ、インクフィルムに塗布されているイン
クを記録紙に転写する従来の熱転写方式と異なり、イン
クフィルム上に塗工された抵抗層に通電することにより
インクフィルム自身を発熱させ、インクを転写する記録
方式であり、その特徴としては、インクフィルム自身が
発熱するから熱効率が良く記録エネルギーが低く、記録
速度が速い。ヘッドが発熱しないから、熱ストレスが小
さ（信頼性が高い。ヘッドへの蓄熱が少なく、熱履歴も
少ない。放熱対策が簡単であるため小型化低コスト化が
容易である。などがあげられる。The energized thermal transfer recording method is different from the conventional thermal transfer method in which a resistor installed on the head substrate generates heat to transfer the ink coated on the ink film to the recording paper. This is a recording method in which the ink film itself generates heat by applying electricity to transfer the ink. Its features include good thermal efficiency, low recording energy, and high recording speed because the ink film itself generates heat. Since the head does not generate heat, there is little thermal stress (high reliability. There is little heat accumulation in the head, and there is little thermal history. Heat dissipation measures are simple, so it is easy to downsize and reduce costs.
その通電熱転写記録方式において用いるインクフィルム
の幅は現在的８ｃｍ〜３０ｃｍであるため、最終的にこ
の長さにスリッティングする必要がある。Since the width of the ink film used in the current thermal transfer recording method is currently 8 cm to 30 cm, it is necessary to finally slit it to this length.
しかし、通電抵抗層を塗工する前にスリッティングする
と、同一条件でかつ均一に大量に作れなくまた塗工に時
間がかかりコストがアップするという欠点を有する。However, if slitting is performed before applying the current-carrying resistance layer, it has the disadvantage that it cannot be uniformly produced in large quantities under the same conditions, and that the application takes time and costs increase.
そこで本発明は、このような問題点を解決するためのも
ので、その目的とするところは、通電熱転写記録媒体を
同一条件で均一にかつ短時間で大量に作るということに
ある。The present invention has been made to solve these problems, and its purpose is to uniformly produce large quantities of electrically conductive thermal transfer recording media under the same conditions in a short period of time.

。In a current-carrying thermal transfer recording medium coated with a current-carrying resistive layer on one side of the base film and an ink layer containing a heat-melting ink or a low-sublimation ink layer on the other side, the entire surface is coated on one side of the base film. Alternatively, it is characterized in that the resistive layer is widely applied in stripes and then slitted.
〔実施例１〕
厚さ６ ｔｔ ｍ １幅９００ｍｍのＰＥＴフィルムの
一方の面に抵抗層を塗工後、約１０ｃｍの幅にスリッテ
ィングを行ない、該抵抗層の反対側にイエロー、マゼン
タ、シアンのインク層をシートの長手方向にダンダラ倹
りでホットメルト塗工した。[Example 1] After coating a resistive layer on one side of a PET film with a thickness of 6 tt m and a width of 900 mm, slitting was performed to a width of about 10 cm, and yellow, magenta, and cyan were coated on the opposite side of the resistive layer. The ink layer was hot-melt coated in the longitudinal direction of the sheet.
〔比較例１〕
厚さ６μｍ幅９００ｍｍのＰＥＴフィルムを約１０ｃｍ
の幅にスリッティングし、一方の面に抵抗層を塗工後、
該抵抗層の反対側にイエロー、マゼンタ、シアンのイン
ク層をシートの長手方向にダ／ダラ塗りでホットメルト
塗工した。[Comparative Example 1] Approximately 10 cm of PET film with a thickness of 6 μm and a width of 900 mm
After slitting to a width of , and coating a resistance layer on one side,
On the opposite side of the resistance layer, yellow, magenta, and cyan ink layers were hot-melt coated in the longitudinal direction of the sheet by dab/dab coating.
上記実施例１では比較例１に比べ非常に均一で塗工量も
同一時間で９倍多くなる。In Example 1, the coating was very uniform compared to Comparative Example 1, and the amount of coating was nine times greater in the same amount of time.
以上述べたように、本発明によれば、通電抵抗層を幅広
く塗工した後スリッティングすることにより均一でかつ
短時間で大量にインクシートを作ることができるという
効果を有する。As described above, the present invention has the effect that ink sheets can be produced uniformly and in large quantities in a short time by applying a current-carrying resistance layer over a wide area and then performing slitting.
