【発明の詳細な説明】
［産業上の利用分野］
本発明は、水性および油性いずれのインクでも記録可能
なシートに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sheet that can be recorded with both water-based and oil-based inks.
［従来の技術］
近年、各種学会、会議等のプレゼンテーション用として
、従来のスライドプロジェクターに替わり、オーバーヘ
ッドプロジェクターが用いられる機会が多くなっている
。また、印刷の分野でも、各種の出版物や、包装等の用
途で、透明な印刷物が求められるようになっている。[Prior Art] In recent years, overhead projectors have been increasingly used instead of conventional slide projectors for presentations at various academic conferences, conferences, and the like. Furthermore, in the field of printing, transparent printed matter is increasingly required for various publications, packaging, and other applications.
これらの透明なシートへの印字、印刷は、基材であるシ

う印刷に比べ印刷の速度や乾燥の面で特別な配慮が必要
である。不透明な基材においても、吸収性に乏し《同様
な配慮が必要な場合も多い。Printing on these transparent sheets requires special consideration in terms of printing speed and drying compared to printing on regular paper because the base sheet itself has no absorbency. . Opaque base materials often have poor absorbency and require similar considerations.
また、オーバーヘッドプロジェクター用のシート等の、

１００〜１０００Åの細孔を持つ多孔性アルミナキセロ
ゲルを有するインクジェット記録媒体も知られている。We also offer sheets for overhead projectors, etc.
In order to obtain small amounts of printed matter, it is widely used to edit the manuscript using a personal computer or word processor and then print it out using a printer.The inkjet method is attracting attention because it is easy to print in full color. The ink-receiving layer has a radius of 40~
Inkjet recording media having porous alumina xerogels with pores of 100 to 1000 Å are also known.

。(Refer to Japanese Unexamined Patent Publication No. 60-245588.) On the other hand, offset printing is a method that can provide high resolution and high quality images. This is a method in which an ink prepared by kneading a pigment and an oil-based vehicle such as unsaturated carboxylic acid glycated is printed together with dampening water via a plate cylinder, a rubber cylinder, and an impression cylinder.
［発明の解決しようとする課題］
しかしながら、透明シートに対して従来の如きインクジ
ェット方式を採用すると、多量のインクが取り扱われる
ため、吸収性の乏しい透明シートへの印字はごく低品位
の場合のみ可能であり、フルカラー化は殆ど不可能に近
かった。[Problem to be solved by the invention] However, when conventional inkjet methods are used for transparent sheets, a large amount of ink is handled, so printing on transparent sheets with poor absorbency is possible only in extremely low-quality cases. Therefore, creating full color was almost impossible.
また、特開昭６０− ２４５５８８号に示されたインク

くなる欠点を有している。そしてこの傾向は基材が透明
材である程著しくなる。Furthermore, in the inkjet recording medium disclosed in JP-A No. 60-245588, alumina xerogel is used as an ink receptor, so the particle size is relatively large and the interparticle gaps are also large. As a result, light scattering occurs, transparency is impaired, and the image becomes whitish. This tendency becomes more pronounced as the base material becomes more transparent.

る。In addition, in offset printing, if the surface to be printed has no absorption capacity, such as glass or plastic, the printability is low and the ink takes time to dry, making it difficult to put it into practical use. The situation is that it relies on gravure printing, etc.
更に、そのスクリーン印刷においても、インクの乾燥に
時間を要する点は同様である。Furthermore, screen printing also requires time for ink to dry.
［課題を解決するための手段］
本発明者はこれら従来法が有する諸欠点を排除し、透明
基材上でさえ印刷を施しても透明性を失わず、かつ十分
にフルカラー発色し得る記録用シートを得ることを目的
として種々研究、検討した結果、特定のアルミナを特定

いることにより前記目的を達成し得ることを見出した。[Means for Solving the Problems] The present inventor has solved the various drawbacks of these conventional methods, and created a recording medium that does not lose transparency even when printed even on a transparent substrate and can sufficiently develop full color. As a result of various studies and examinations aimed at obtaining a sheet, it was discovered that the above object could be achieved by using a specific alumina with a specific pore volume as an ink-receiving layer on the sheet.

The total volume is O. lcc/g or more 0.
An object of the present invention is to provide a recording sheet characterized in that it has a density of less than 4 cc/g.

来る。Further, the thickness of the base material is selected depending on the purpose and is not particularly limited. When these base materials are used, they can be subjected to surface treatment such as corona discharge treatment or provided with a precoat layer in order to improve adhesion to the ink-receiving layer described later.
本発明におけるインク受容体としては擬ベーマイトが用

吸着能とは次の様に定義される。As pseudo-boehmite, the adsorption capacity is 20 to 100 mg/g.
It is preferable to have the following. Note that the adsorption capacity used in the present invention is defined as follows.

An aqueous solution containing 2% by weight of Food Black 2 was added dropwise at a rate of 1 cc/min while stirring, and at the point where the liquid started to be colored, the dye solids adsorbed on the powder (mg/min) were added. g).

If the total volume of pores with less than 0 Å is 0. Ice/g or more 0. It needs to be less than 4cc/g. If the radius and its total volume deviate from the above range, light scattering will occur and the printed image will be whitish, making it difficult to print in full color, which is inappropriate.

きるので望ましい。The layer thickness of such pseudo-boehmite is appropriately selected depending on the amount of ink used for printing and printing, but it is generally appropriate to adopt a layer thickness of about 1 to 20 μm. If the layer thickness deviates from the above range, the color development may become unstable or transparency may be impaired, which is not preferable. As a means of providing a pseudo-boehmite layer on a transparent substrate, there is a method of applying a mixed slurry of pseudo-boehmite and a binder onto the substrate using various coaters such as a roll coater, an air knife coater, a blade coater, a mouth coater, and a bar coater, and then drying it. Mainly used. Pseudo-boehmite is desirable because a preferable ink-receiving layer can be easily obtained by using its sol.

It is appropriate to adopt approximately % by weight. The pore size distribution in the present invention was measured by the nitrogen adsorption/desorption monitoring method (Omnisorb 100 manufactured by Omicron Technology).
