Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 シートの自己発色による複写が必要な部分に のみ自己発色部を形成することにより、自己発色剤の無 駄が生ぜず、また、自己発色部以外の部分において、不 用意な発色汚れが生ずることなく、さらに、加圧転写方 式により容易に自己発色部を形成する感圧自己発色シー トおよびその作成方法の提供。 【課題の解決手段】 シートの複写記入部に対応して染 料内包マイクロカプセル剤と顕色剤とからなる自己発色 部が形成されてなり、前記染料内包マイクロカプセル剤 のマイクロカプセルは、平均粒径5μm以下であること を特徴とする感圧自己発色シートおよびシートの複写記 入部に対応して顕色剤を塗布した後、顕色剤層上に染料 内包マイクロカプセル剤を加圧転写方式により印刷し て、自己発色部を形成して作成することを特徴とする感 圧自己発色シートの作成方法。 (57) [Problem] To form a self-coloring portion only on a portion of a sheet that needs to be copied by self-coloring, so that no waste of a self-coloring agent is generated, and in a portion other than the self-coloring portion, there is no waste. Provided is a pressure-sensitive self-coloring sheet capable of easily forming a self-coloring portion by a pressure transfer method without generating a prepared coloring stain, and a method for producing the same. A self-coloring portion composed of a dye-containing microcapsule and a developer is formed corresponding to a copy entry portion of a sheet, and the microcapsules of the dye-containing microcapsule have an average particle size. A pressure-sensitive self-coloring sheet characterized by being 5 μm or less, and a color developing agent corresponding to a copy entry portion of the sheet, and then a dye-encapsulated microcapsule is printed on the color developing layer by a pressure transfer method. And forming a self-coloring portion to form a pressure-sensitive self-coloring sheet.
