【発明の詳細な説明】 ［産業上の利用分野］ 本発明はオーバーヘッドプロジェクタ用フィルム（以
下O.H.P用フィルムと称す）に関するものである。Description: TECHNICAL FIELD The present invention relates to a film for an overhead projector (hereinafter, referred to as an OHP film).
［従来技術及びその問題点］ 従来O.H.P用フィルムはポリエステル、アセテート、
ポリカーボネート等の単体透明プラスチックフィルムが
用いられていたが、近年O.H.P用フィルムへの記録方法
として、パーソナルコンピューター等の端末として使用
されているドットプリンターによる印刷が急速に要望さ
れるようになってきた。[Prior art and its problems] Conventional OHP films are polyester, acetate,
Although a single transparent plastic film such as polycarbonate has been used, printing by a dot printer used as a terminal of a personal computer or the like has recently been rapidly demanded as a recording method on an OHP film.
しかしながら、ドットプリンターに使用されるインク
リボンのインクは主成分が不乾性油である為、透明プラ
スチックフィルム上に印刷を行なうとインクの定着性が
悪く、手でこするとすぐに印字が取れたり乱れたりして
印刷後の保存性に大きな欠点を有していた。前記欠点を
補正する為、透明プラスチックフィルム上にマット剤を
適当なバインダー剤を用いてコーティングされたO.H.P
用フィルムも存在するが、ドットプリンターで印刷した
場合インク定着に時間がかかったり、また、マット剤を
コーティングしている為、実際にO.H.P用フィルムで映
写した場合の画面が鮮明度を失うという欠点を生じてい
た。However, since the main component of the ink of the ink ribbon used for dot printers is non-drying oil, printing on a transparent plastic film has poor fixability of the ink. On the other hand, it has a serious drawback in storage stability after printing. OHP coated with a matting agent on a transparent plastic film using an appropriate binder to correct the above-mentioned defects
There is also a film for printing, but when printing with a dot printer, it takes time to fix the ink, and because it is coated with a matting agent, the screen loses sharpness when actually projected on an OHP film. Was occurring.

性を損なわせないことを目的とするものである。[Means and Object of the Invention] The present invention provides a layer containing a styrene-butadiene copolymer and an adhesive resin on a transparent plastic film to quickly fix ink on an ink ribbon used in a dot printer, and The purpose of the present invention is to prevent the transparency of the film from being impaired.
［発明の構成］ 本発明は透明プラスチックフィルムの少なくとも片面

−ブタジエン共重合体が該インクリボンの主成分である
不乾性油に対し非常に良好な相溶性を示し、なおかつ、
不乾性油をすばやく吸収してしまうのではないかと推察
される。[Constitution of the Invention] The present invention is an OHP film in which a layer containing a styrene-butadiene copolymer and an adhesive resin is provided on at least one surface of a transparent plastic film. Why O.
It is not clear whether the HP film fixes the ink of the dot printer ink ribbon quickly, but the styrene-butadiene copolymer shows very good compatibility with the non-drying oil which is the main component of the ink ribbon, And
It is speculated that the non-drying oil may be absorbed quickly.
また、スチレン−ブタジエン共重合体だけでは透明プ
ラスチックフィルムへの接着性が不十分な為、該スチレ

つ、透明で十分に該フィルムへの接着力を擁する接着性
樹脂とを含む層を該フィルム上へ設ける。前記スチレン
−ブタジエン共重合体と接着性樹脂の重量比は、好まし
いのは90/10〜10/90の範囲であり、特に好ましいのは80
/20〜20/80の範囲である。前記比が90/10より大きくな
ると、本発明でいう層の該フィルムへの接着力が弱くな
りすぎて手でこすったりすると取れてしまう。また、10
/90以下だと該スチレン−ブタジエン共重合体のインク
吸収力効果がうすれてしまう。Further, since the styrene-butadiene copolymer alone has insufficient adhesiveness to a transparent plastic film, the styrene-butadiene copolymer exhibits good compatibility with the styrene-butadiene copolymer, and is transparent and sufficiently adherent to the film. And a layer containing an adhesive resin having the following. The weight ratio of the styrene-butadiene copolymer and the adhesive resin is preferably in a range of 90/10 to 10/90, and particularly preferably 80.
/ 20 to 20/80. If the ratio is greater than 90/10, the adhesive strength of the layer according to the present invention to the film is too weak to be removed by hand rubbing. Also, 10
If it is less than / 90, the effect of the styrene-butadiene copolymer on ink absorption will be diminished.
