〔産業上の利用分野〕
本発明はオーバヘッド プロジェクタに用いる媒体であ
るフィルムに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a film that is a medium used in an overhead projector.
従来、この種のオーバヘッド プロジェクタに用いる媒
体は透明性を有した塩ビ系、ポリエステル、ポリイミド
系のフィルムを用いている。このフィルムに記入するに
は油性インクを用いている。Conventionally, the medium used in this type of overhead projector is a transparent vinyl chloride film, polyester film, or polyimide film. Oil-based ink is used to write on this film.
今日では印刷機械で書込むことが多くなっている。その
一つに、Ｘ−Ｙプロッタがあり、やはり油性インクが用
いられるが、一般には分解能が低い。Nowadays, writing is often done with printing machines. One of them is an X-Y plotter, which also uses oil-based ink, but generally has low resolution.
しかし、Ｘ−Ｙプロッタ、インクジェットプリンタにお
いても水性インクが多く用いられている。However, water-based inks are also often used in X-Y plotters and inkjet printers.
この水性インクでは媒体に記録を残すことが困難であっ
た。It was difficult to leave a record on the medium with this water-based ink.
本発明の目的は上記欠点である水性インクを用いて記録
できる、特にインクジェットプリンタで記録できるよう
にしたオーバヘッド プロジェクタ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 an overhead projector that can be recorded using aqueous ink, and in particular, can be recorded with an inkjet printer.
本発明は透明性フィルム１に透明性を有する微粒子３を
塗布して構成したものである。The present invention is constructed by coating a transparent film 1 with transparent fine particles 3.
透明性フィルム１上に塗布した微粒子３でインクを保持
することにより、水性インクによるオーバヘッド プロ
ジェクタ用フィルムへの記録を可能にする。By retaining the ink with the fine particles 3 coated on the transparent film 1, it is possible to record on the overhead projector film using the aqueous ink.
次に本発明の実施例について図面を参照して説明する。 Next, embodiments of the present invention will be described with reference to the drawings.
（実施例１） 第１図は本発明の第１の実施例を示す断面略図である。(Example 1) FIG. 1 is a schematic cross-sectional view showing a first embodiment of the present invention.
本発明に係るオーバヘッド プロジェクタ用フィルムは
透明性フィルム１上に透明性接着剤２により透明性を有
する微粒子３を塗布して構成したものである。The film for an overhead projector according to the present invention is constructed by coating transparent fine particles 3 on a transparent film 1 using a transparent adhesive 2.
ここで透明性フィルム１は多くは塩ビ系材料、ポリイミ
ド系材料、ポリエステル系、ポリスチレン系材料などが
用いられている。Here, the transparent film 1 is often made of a vinyl chloride material, a polyimide material, a polyester material, a polystyrene material, or the like.
透明性微粒子３としてはガラスピーズとか、合成樹脂球
状マイクロビーズ等が良い。合成樹脂球状マイクロピー
ズは架橋ポリスチレン、ポリスチレン、アクリル系樹脂
等によシ作ることができる。The transparent fine particles 3 are preferably glass beads, synthetic resin spherical microbeads, or the like. Synthetic resin spherical micropeads can be made from crosslinked polystyrene, polystyrene, acrylic resin, etc.
微粒子の径は小さい方がよいが、小さすぎてもその効果
は少なく、５−５０μｍ位がよいＱ又、塗布量は３〜２
０μｍ位がよいが、インク量によっても差がある。文字
のみの場合、分散ドツトにより作画する場合は薄くてよ
く、ベタ印字が多い場合は厚く塗布しておくことがイン
クを保持するのに良い。The smaller the diameter of the fine particles, the better, but if it is too small, the effect will be small, so it is better to have a diameter of 5-50 μm.Also, the amount of coating should be 3-2
A value of about 0 μm is preferable, but there is also a difference depending on the amount of ink. In the case of only characters, it is sufficient to apply a thin layer when drawing by dispersed dots, and when there are many solid prints, it is better to apply a thick layer in order to retain the ink.
（実施例２） 第２図は本発明の第２の実施例を示す断面略図である。(Example 2) FIG. 2 is a schematic cross-sectional view showing a second embodiment of the invention.
第２図において、本発明に係るオーバヘッドプロジェク
タ用フィルムは透明性フィルム１上に高吸水性ポリマー
を含有させた透明性接着剤２を塗布し、さらに透明性を
有する微粒子３を塗布して構成したものである。In FIG. 2, the overhead projector film according to the present invention is constructed by coating a transparent film 1 with a transparent adhesive 2 containing a highly absorbent polymer, and further coating with transparent fine particles 3. It is something.
透明性フィルム１は多くは塩ビ系、ポリエステル、ポリ
スチレン、ポリプロピレン、ポリイミド系の材料等が用
いられている。The transparent film 1 is often made of vinyl chloride, polyester, polystyrene, polypropylene, polyimide, or the like.
透明性微粒子３にはガラスピーズとか、合成樹脂球状マ
イクロピーズ等が良い。The transparent fine particles 3 are preferably glass beads, synthetic resin spherical micropeas, or the like.
合成樹脂球状マイクロビーズは架橋ポリスチレン、ポリ
スチレン、ポリエチレン、アクリル系樹脂等により作る
