いる。[Prior Art 1 Conventionally, US Patent No. 439920 is shown as an example of a pressure-sensitive medium.
The photosensitive pressure-sensitive recording medium proposed in No. 9 includes a photosensitive pressure-sensitive medium in which microcapsules containing a dye precursor, a photocurable resin, and a photopolymerization initiator as main inclusions are carried on the surface layer, and It consists of a color developing medium whose surface layer carries a substance that develops color by reacting with a dye precursor contained in the colorant, a so-called color developer. An image recording device using this image recording medium irradiates the surface of the photosensitive pressure sensitive medium with light based on image information, hardens the photocurable resin with the irradiated light, and then applies a color developing medium to the surface of the photosensitive medium. By overlapping and applying pressure, the uncured microcapsules are destroyed, thereby causing the dye precursor inside them to react with the color developer on the surface of the color development medium to form a visible image on the surface of the color development medium. This is already known from Japanese Patent Application Laid-open No. 173981/1983.

顕色剤シートの上の画像濃度が十分高くならないという
間ｍ点があった。[Problem to be solved by the invention 1 However, color developing medium (hereinafter also referred to as color developer sheet)
If so-called plain paper made from pulp is used as a base, when the uncured microcapsules are destroyed by stacking them with a photosensitive recording medium and applying pressure, most of the pressure will compress the base plain paper. This results in insufficient destruction of the microcapsules. For this reason,
There was a point m during which the image density on the developer sheet was not sufficiently high.
Ｗ通紙をベースとした顕色剤シートでも十分な画像濃度

てに送る場合で、総圧力が約１２００−１６００Ｋｇに
もなり、圧力現像装置そのものが非常に高い剛性を必要
としていた。In order to obtain sufficient image density even with a color developer sheet based on W paper, for example, with a pressure developing roller with a diameter of 10 coins, the pressing force per unit length must be approximately 60 to 80K.
Requires g/c-. This is the case when A4 size paper is fed vertically, and the total pressure is about 1200-1600 kg, requiring the pressure developing device itself to have extremely high rigidity.
また、圧力現像装置の体積や重量も大きいものとなる上
に、装置が高価なものになっていた。Moreover, the volume and weight of the pressure developing device are large, and the device is also expensive.

とを示すものである。FIG. 4 is a graph showing the maximum image density on the developer sheet when several papers with different densities are used as the base of the developer sheet. According to this, relatively high-density art paper ■■ is relatively low-density t
! It can be seen that a considerably high density can be obtained even when the paper is passed through. Needless to explain, this indicates that most of the pressure applied by the pressure developing device was used only for destroying the microcapsules.
顕色剤シーシのベースとして、このような高密度の用紙
を用いることは、ランニングコストが高くなるという問
題があり、低密度で廉価な普通紙などの用紙を用いる方
法が望まれていた。Using such high-density paper as a base for the color developer sheet has the problem of high running costs, and a method using low-density, inexpensive paper such as plain paper has been desired.
また、上述のことは感圧記録媒体についても同様である
。Furthermore, the above also applies to pressure-sensitive recording media.

As a result, even if relatively low-density plain paper is used as the base of the color developer medium, high-density images can be obtained that are equivalent to those obtained with a color developer medium that uses a high-density base from the beginning. . Furthermore, before performing pressure development, the base of the pressure-sensitive recording medium is previously pressurized to make it highly dense, and then the microcapsules and the color developer are attached to the base to form the pressure-sensitive recording medium.

ることを特徴とする画像記録方法。A pressure-sensitive medium that supports microcapsules that encapsulate a dye precursor and whose mechanical strength changes when energy is applied thereto, and a color developing medium that supports a color developer that causes a color reaction with the dye precursor. or by applying energy to a pressure-sensitive recording medium to form a latent image and applying pressure to the microcapsules to destroy them. An image recording method for obtaining an image on the pressure-sensitive medium or color developing medium by reacting a dye precursor and a color developer,
The method is characterized in that the carrier, which is the base of the color developing medium or the pressure-sensitive medium, is pressurized in advance, the microcapsules or the color developer are attached thereto, and then energy is applied to the pressure-sensitive medium to form a latent image. Image recording method.
