Description
【発明の詳細な説明】
〔産業上の利用分野〕
本゛発明はオニバヘッドグロジエクタに用いられるフィ
ルムシートに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a film sheet used in an Onibahed Glodiector.
従来のオーバヘッドプロジェクタ（０，Ｈ，Ｐ）用フィ
ルムは油性のインクによシ作画されて使用されていた。Conventional films for overhead projectors (0, H, P) have been printed with oil-based ink.
近年、水性インクを用いたインクジェットプリンタが出
現しているが、このプリンタでＯ，Ｈ，Ｐフィルムに作
画プリントを行うと、水性インク故に画像が流れてしま
う。In recent years, inkjet printers using water-based inks have appeared, but when images are printed on O, H, and P films using these printers, the images tend to bleed due to the water-based inks.
又、作画できても乾燥せず、定着−性が悪く、かさねた
シ保存することができないという欠点を有している。Further, even if an image can be drawn, it does not dry, has poor fixing properties, and cannot be stored in layers.
本発明の目的は、水性インクにおいて作画しても十分な
定着性を有するようにした０、Ｈ，Ｐ用フィルムを提供
することにある。An object of the present invention is to provide a film for 0, H, and P which has sufficient fixing properties even when drawing with aqueous ink.
〔問題点を解決す、５′九“めの手段〕本発明は透明性
フィルムの表面にアクリル酸系重合体を塗布したもので
ある。[5'9'' Means for Solving the Problems] The present invention is a transparent film coated with an acrylic acid polymer on its surface.
透明性フィルムの表面に塗布したアクリル酸系重合体に
より水溶性インクを保持して、作画、色付けを可能にす
る。The acrylic acid polymer applied to the surface of the transparent film retains water-soluble ink, making drawing and coloring possible.
次に本発明の実施例について説明する。 Next, examples of the present invention will be described.
オーバヘッドプロジェクタ用の透明性フィルムとしては
多くは塩化ビニール系、ポリエステル系が採用されてい
る。当然、これ以外のものでも透明性、保守性が保たれ
ればよい。Most transparent films for overhead projectors are made of vinyl chloride or polyester. Of course, other methods may be used as long as transparency and maintainability are maintained.
水性インクを用いることから、瞬間の吸水性を有する材
料を該透明性フィルムの表面に塗布すればよい。吸水性
にすぐれたものとして、本発明においてはアクリル酸重
合体を用いることを特徴としている。Since water-based ink is used, a material that has instantaneous water absorbency may be applied to the surface of the transparent film. The present invention is characterized by the use of acrylic acid polymer as it has excellent water absorbency.
アクリル酸重合体において大別して次のものがある。１
つはアクリル酸・ビニルアルコール共重合体であシ、他
はアクリル酸ソーダ共重合体、他にはアクリル酸ソーダ
アクリルアミド共重合体がある・アクリル酸・ビニルア
ルコール共重合体は特に耐久性に優れている。Acrylic acid polymers can be broadly classified into the following types. 1
One is acrylic acid/vinyl alcohol copolymer, the other is sodium acrylate copolymer, and the other is sodium acrylate acrylamide copolymer.Acrylic acid/vinyl alcohol copolymer is particularly durable. ing.
アクリル酸ソーダ共重合体は吸水速度が特に速く、吸水
性にもすぐれている。Sodium acrylate copolymer has a particularly fast water absorption rate and excellent water absorption.
アクリル酸ソーダアクリルアミド共重合体は繊維状にで
きており、塗布が容易である。ただし、多少黄色を有し
ている。Sodium acrylate-acrylamide copolymer is made of fibers and is easy to apply. However, it has some yellow color.
本発明は以上説明したように、アクリル酸系重合体を塗
布したので、水性インクを用いてインクジェットプリン
タにより作画を行なうことができるとともに、カラー作
画も容易に作成できる効果を有するものである。As explained above, since the present invention coats an acrylic acid polymer, it is possible to draw images using an inkjet printer using water-based ink, and it also has the effect that color drawings can be easily created.
