ものである。[Detailed description of the invention] [Industrial field of application] The present invention relates to a transparent inkjet recording sheet, and is mainly used in overhead projectors (hereinafter referred to as OHP) that observe images through a transparent object.
The invention relates to recording sheets for use in cameras (hereinafter referred to as "printed sheets") and recording sheets for displays in which images are observed by illuminating them from the back.

The inkjet recording method is a method in which small droplets of ink are ejected through a nozzle, and the ink droplets are attached to and absorbed by a recording medium to perform recording. The recording medium commonly used in this system is a porous sheet, which is generally opaque. Also,
The inks commonly used in this method are composed of direct dyes, acid dyes, or basic dyes, water, and glycols, and the apparent drying of the ink is due to the ink droplets entering the porous voids of the sheet. It is done by hand.
ところで、本考案が目的とするインクジエツト
記録用シートは上述のような不透明なシートでは
なく、高い透明性を有するものであり、OHP用
記録シートにおいては特にこの特性が重要であ
る。 Incidentally, the inkjet recording sheet to which the present invention is directed is not an opaque sheet as described above, but has high transparency, and this property is particularly important in OHP recording sheets.
ところが、この透明という特性は記録中、記録
後の画像が見いくいという欠点を有するのであ

いため、インクの乾燥速度は極めて遅く、１週間
以上もかかる。その上、インクの流れの問題もあ
り、実用化は困難であつた。 On the other hand, when recording is performed directly on a highly transparent recording medium, such as a polyester film, using an ordinary water-based inkjet ink, it is non-porous, so unlike the case with a porous sheet, Since the ink does not enter the voids, the drying rate of the ink is extremely slow, taking more than a week. In addition, there were problems with ink flow, making it difficult to put it into practical use.

不満足なものであり、従来技術の最大の欠点とい
える。 As a conventional technique for improving this problem, as shown in Japanese Patent Application Laid-Open No. 80489/1989, a method is disclosed in which a substance that dissolves or swells with ink is provided on a non-porous recording medium. For example, even if 10 g/m 2 of methylcellulose or sodium polyacrylate is coated on a polyester film as a solid content, it takes more than 60 minutes for the ink to dry, which is hardly practical. Furthermore, in JP-A-59-174382, 4 parts by weight of polyvinyl alcohol, 16 parts of polyvinylpyrrolidone, 4 parts of dibenzylidene sorbitol,
The thickness of the ink absorbing layer after drying the coating composition consisting of 76 parts, NN dimethyl formaldehyde is approximately
A recording material coated and dried on a polyester film with a thickness of 10μ is shown, but it still takes about 10 minutes for the ink to dry. Under these current circumstances, if you want to avoid back-printing, the printed sheet must be left to cool for about 10 minutes or more until the ink dries completely. This is extremely unsatisfactory considering normal usage conditions, and can be said to be the biggest drawback of the prior art.

The present invention has been proposed to solve the above problems. That is, the composite sheet for inkjet recording of the present invention is made by overlapping a transparent sheet and paper and bonding a portion of them together.

処理を行なつたフイルムである。 The inkjet recording sheet used in this case is a transparent sheet, which is a film obtained by performing an improvement treatment on various synthetic resin films including polyester film to make it suitable as an inkjet recording sheet.

め不適当である。白色度は記録画像が見やすいも
のであれば特に制限はない。 Although there are no particular restrictions on the paper, extremely large size paper or highly water-repellent paper is not preferred because the image will smear when stacked on the recording surface. In addition, a paper with too low surface strength is not suitable because when it is superimposed on a recorded image, the paper fibers come off and stick to the recording surface. There is no particular restriction on the whiteness as long as the recorded image is easy to see.
シートと紙の結合方法としては、接着剤、ある
いは粘着剤で結合させる方法が考えられる。 Possible methods for bonding the sheet and paper include bonding with adhesive or adhesive.

５図が考えられる。 In FIGS. 1 to 5, reference numeral 1 indicates a transparent sheet for inkjet recording. As mentioned above, this sheet is a highly transparent non-porous recording medium.
The positions shown in FIGS. 1 and 5 are conceivable as the positions where the sheet and paper are joined.

As mentioned above, the composite sheet for inkjet recording of the present invention significantly accelerates the apparent drying of ink by overlapping paper on the recording surface, and also has the effect of preventing reverse transfer, so even sheets immediately after recording can be overlapped. This enabled the practical use of transparent sheets for inkjet. Further, since the recording sheet and the paper overlap, there is an advantage that the image after recording is extremely easy to see during recording.
