The recording material used for recording with an inkjet recording device or the like is general paper such as high-quality paper, pound paper, writing paper, or art paper.

しかし、近年、インクジェット記録装置やペンプロッタ
−等の記録機器の発達に伴い、前述した従来の被記録材
では充分な記録特性が得られてぃない。However, in recent years, with the development of recording devices such as inkjet recording devices and pen plotters, sufficient recording characteristics cannot be obtained with the conventional recording materials mentioned above.
すなわち、上記の如き近年の記録方法では、従来とは比

Conventional recording materials have not reached satisfactory levels in ink absorption, color development when a plurality of inks are deposited on the same location, chromaticity, and the like.

−２１４９８９号公報には、多孔質インク吸収性樹脂層
を基材上に設けてなるシートが記載されている。In order to solve these problems, coated paper having a porous ink-absorbing layer on the surface of the base material, such as inkjet paper, has been devised.
Japanese Patent No. 214989 describes a sheet having a porous ink-absorbing resin layer provided on a base material.
このインク吸収層は、多孔質であり、内部に細孔や亀裂
を含んでいるため、インク吸収速度が向上するというも
のである。This ink absorption layer is porous and contains pores and cracks inside, which improves the ink absorption speed.
このように、多孔質インク吸収層を設けることにより、
ある程度、インク吸収性を高めることは可能であるが、
吸収層が多孔質であるがため、被記録材が光拡散性を有
し、鮮明で光学濃度の高い記録画像および光沢のある記
録画像が得られない。In this way, by providing a porous ink absorption layer,
Although it is possible to increase ink absorption to some extent,
Since the absorption layer is porous, the recording material has light diffusing properties, making it impossible to obtain clear recorded images with high optical density and glossy recorded images.
また、インクの記録面から記録画像を観察するため、記
録剤をできるだけ吸収層表面に残留せしめる構成をとっ
ており１画像の耐水性や耐摩擦性等の耐久性や保存性に
劣ると云う欠点がある。In addition, since the recorded image is observed from the ink recording surface, the recording agent is left on the surface of the absorbing layer as much as possible, which has the disadvantage of poor durability such as water resistance and abrasion resistance of one image and poor storage stability. There is.

付着されたインクが顔料により吸着され。As one method for solving such problems, a recording medium disclosed in, for example, Japanese Unexamined Patent Publication No. 136480/1980 is known. This recording medium has at least one highly white ink-receiving layer provided on a support, and the formed image is observed from the support. In this method, various performances such as water resistance on the viewing surface have been sufficiently resolved, but a large amount of pigment is used to increase the whitening of the ink receiving layer, and as a result, although the whitening is high,
The attached ink is adsorbed by the pigment.
インク受理層と支持体との界面に達するインクの量が少
なくなるため、観察面における画像濃度を十分に高くす
ることができず、また色彩性や解像度等も劣るという欠
点がある。Since the amount of ink that reaches the interface between the ink-receiving layer and the support is small, the image density on the viewing surface cannot be sufficiently high, and the color properties and resolution are also poor.

被記録材が必要になってきた。In other words, there is a need for recording materials that are significantly superior to conventional recording materials in all aspects of recording performance, including ink absorption, recording agent color development, recorded image quality, resolution, color, recorded image density, and gloss. It's here.
本発明者は、上記の如き被記録材を提供すべく研究の結

問題が生じた。However, in the recording materials of these prior inventions,
The correlation between various required performances, such as the ink absorbency 1 strength of the formed ink transport layer, the relationship with the ink retention layer, and the relationship with the quality of the formed image, is not clear, and it is difficult to improve certain types of performance. 0 For example, if the ink transport layer is made thicker to improve ink absorption, the image density may be reduced, and if it is too thin, the resolution may be reduced. Too many particles may cause cracks in the ink transport layer or severe powder fall-off, while too few particles may cause various problems such as insufficient ink absorbency.

There is a demand for a recording material that can provide an image that has the same characteristics as those described above.

録材である。(Means for Solving the Problems) That is, the first invention has an ink transport layer and an ink holding layer containing non-staining particles and a binder with respect to the recording material. The difference in refractive index between the particles contained in the ink transport layer and the binder is ±0. This is a recording material characterized in that it is O1 or more.

This recording method is characterized in that the difference in refractive index between the particles contained in the ink transport layer of the recording material and the binder is ±0.01 or more.

Forming an ink transport layer from particles with a specific refractive index difference and a binder is the most important factor for the image quality after recording. By forming an ink transport layer using a binder and a binder, the background of the formed image becomes moderately light-diffusing, and the above-mentioned image quality is greatly improved by causing moderate whitening. It was something that
（作 用）
本発明の被記録材は、記録面と観察面が同一で′ある従
来の被記録材とは異なり、記録面と観察面とが表裏関係
にある。(Function) The recording material of the present invention is different from conventional recording materials in which the recording surface and the viewing surface are the same, and the recording surface and the viewing surface are in a front-back relationship.
すなわち、本発明の被記録材は、基本的にはインク輸送
層にインクを以って記録を行い、インク保持層側から記
録画像を観察するものである。That is, in the recording material of the present invention, recording is basically performed using ink on the ink transport layer, and the recorded image is observed from the ink retaining layer side.
本発明を第１に特徴づけるインク輸送層は、特定の屈折
率差を有する粒子と結着剤とを主体として構成され、通
液性を有し、その表面に付着したインクを速やかに吸収
、透過せしめる機能を有し、一方、インク保持層は、前
記インク輸送層から移行してきたインク若しくは記録剤
を吸収、保持するＩｌ使を有するものである。The ink transport layer, which primarily characterizes the present invention, is mainly composed of particles having a specific refractive index difference and a binder, has liquid permeability, and quickly absorbs ink adhering to its surface. On the other hand, the ink retaining layer has an Il agent that absorbs and retains the ink or recording agent transferred from the ink transport layer.
この際、インク輸送層は、インク中の液媒体に対して親
和性が高くなければならないと同時に。At this time, the ink transport layer must have high affinity for the liquid medium in the ink.
記録剤（染料、顔料等の着色剤および発色性を有する材
料）に対しては、逆に吸着性が低くなければならない。On the contrary, the adsorption property for recording agents (coloring agents such as dyes and pigments and materials having color-forming properties) must be low.
従って、インク輸送層は、インク媒体に対しては、濡れ
、浸透、拡散等の特性を持ち、記録剤に対しては、吸着
、浸透、反応等の特性を持たない材料を選択して構成さ

くなければならない。The ink retaining layer, which is the second feature of the present invention, must have a stronger ability to absorb ink than the ink transport layer in order to stably absorb and capture the ink temporarily absorbed by the ink transport layer.
従って、インク保持層は、インク媒体に対すると同様に
、記録剤に対しても高い親和性を有していなければなら
ない。Therefore, the ink retaining layer must have high affinity for the recording agent as well as for the ink medium.

尚、前述したとおり、本発明は、記録画像を記録側とは
反対の側から観察するものであるために、基材は透光性
を有することが必要である。Note that, as described above, in the present invention, since a recorded image is observed from the side opposite to the recording side, the base material needs to have light-transmitting properties.

。Furthermore, the base material used may be subjected to any processing as long as it ultimately has translucency.1 For example, the base material may be given a desired pattern, appropriate gloss, or silky texture. It is possible to apply a pattern. Furthermore, by selecting a base material having water resistance, abrasion resistance, etc., it is also possible to impart water resistance, abrasion resistance, etc. to the image observation surface of the recording material.

ｊ１！通孔を有する多孔質構造を形成することである。In order to exhibit appropriate liquid permeability, it is necessary to have an appropriate porosity. Appropriate liquid permeability as used in the present invention means that ink can pass through the ink retaining layer in accordance with the ink absorbency. A preferred embodiment for adjusting the liquid permeability of the ink transport layer, which refers to the property that the recording agent in the ink does not substantially remain in the transport layer, is a suitable amount of aIIO inside the ink transport layer.

記録画像の解像力が低下し、高品質の記録画像を形成し
えなくなるからである。The ink retaining layer needs to have a stronger ink absorption ability than the ink transport layer. This is because when the absorption power of the ink retention layer is weaker than the absorption power of the ink transport layer, the ink applied to the surface of the ink transport layer passes through the transport layer, and the tip of the ink retains the ink. When you reach the layer,
When the ink stays in the ink transport layer, the ink permeates and diffuses in the ink transport layer in the lateral direction at the interface between the ink transport layer and the ink retention layer. the result,
This is because the resolution of the recorded image decreases, making it impossible to form a high-quality recorded image.
また、前述のように、記録画像を記録面と反対側から観
