本発明は画像記録媒体及び画像記録方法に関し、詳しく
は、支持体上に特定の樹脂層を設けて画像記録媒体とし
、この画像記録媒体を画像形成に利用した記録方法に関
する。Detailed Description of the Invention [Industrial Application Field] The present invention relates to an image recording medium and an image recording method, and more specifically, a specific resin layer is provided on a support to form an image recording medium, and this image recording medium is This invention relates to a recording method used for image formation.
画像記録媒体及び方法には多くが知られているが、その
うちの一つである感熱転写記録方式は騒音が発生せず、
また、現像・定着にあたって大がかりな処理を必要とし
ない点ですぐれたものである。しかし、この感熱転写記
録方式はサーマルヘッドに供給する電力及びサーマルヘ
ッドに被記録紙を加圧するローラーの圧力にいずれも一
定の限度があるため高品質の印字を得るには薄くて平滑
な熱転写専用紙しか使用しえないといった問題がある。There are many known image recording media and methods, one of which is the thermal transfer recording method, which does not generate noise.
Furthermore, it is excellent in that it does not require extensive processing for development and fixing. However, this thermal transfer recording method has certain limits on both the power supplied to the thermal head and the pressure of the roller that presses the recording paper against the thermal head, so in order to obtain high quality prints, it is necessary to use thin and smooth thermal transfer. The problem is that only paper can be used.
もっとも、こうした問題を解消するものとして、（１）

紙に融着記録像を転写させる（特公昭５９−１６９３２
号公報など）等が提案されている。However, as a solution to these problems, (1)
A heating element is arranged on one side of the sheet so that that side is in contact with the heating element, and a means for conveying ink that has plasticity at room temperature or in a heated state and whose adhesive strength increases when heated is arranged at a position facing the heating element. Further, an ink supply means is disposed in the ink conveyance means to supply the ink after smoothing it into a plastic state,
A heating element in contact with the sheet is driven to generate heat distribution on the sheet, and this heat distribution causes ink to adhere to the sheet (Japanese Patent Publication No. 59-22674, etc.), (2)
A flexible, thin-film image recording medium is selectively heated with a thermal head to fuse a recorded image of a colored material that exhibits heat-fusibility to it, and then plain paper is closely attached to this fused recorded image to form an ordinary sheet of paper. Transferring a fused recorded image onto paper (Special Publication No. 59-16932)
Publications, etc.) have been proposed.
だが、前記（１）では被記録紙である普通紙の厚さが記
録特性に大きな影響を与えるため、普通紙に厚手のもの

記録像を普通紙に転写させる際に加熱ローラーを用いる
必要から、記録前のウオームアツプに時間がかかり、ま
た、消費電力が多くかかり、装置の大型化も避けられな
いといった問題を残している。However, in (1) above, the thickness of the plain paper used as the recording paper has a great influence on the recording characteristics, so thick plain paper cannot be used. On the other hand, in (2) above, it is necessary to use a heated roller when transferring the fused recorded image onto plain paper, which takes time to warm up before recording, consumes a lot of power, and avoids increasing the size of the device. However, the problem remains that it is not possible to do so.

Although the phenomenon of why the wettability of the block polymer improves has not been clarified, the molecular chains become more mobile due to heating, and the -COOCH3 and -OH groups of the block polymer move to the surface. This seems to be due to the fact that it becomes easier to wet with tension liquid. Therefore, the heating temperature of the AB type copolymer resin is higher than its glass transition temperature, more preferably higher than its softening point temperature.
