Abstract:
(EN) The present invention relates to: a N,N'-diarylurea derivative represented by general formula (1); and a manufacturing method thereof. Also, the present invention relates to a thermosensitive recording material in which a thermosensitive recording layer, which contains a colorless or light-colored basic dye at room temperature, and a coloring agent capable of coloring upon contacting said basic dye by heating, is provided on a support, wherein the coloring agent is the N,N'-diarylurea derivative represented by general formula (1) (in the formula, R2 is an alkyl group, an aralkyl group, or an aryl group, A1 represents a hydrogen atom or an alkyl group.).
(FR) La présente invention concerne un dérivé de N,N'-diarylurée représenté par la formule générale (1) ; et un procédé de fabrication de celui-ci. La présente invention concerne également un matériau d'enregistrement thermosensible dans lequel une couche d'enregistrement thermosensible, qui contient un colorant basique incolore ou de couleur claire à température ambiante, et un colorant capable de colorer lors de la mise en contact dudit colorant basique par chauffage, est disposé sur un support, l'agent colorant étant le dérivé de N,N'-diarylurée représenté par la formule générale (1) (dans la formule, R2 est un groupe alkyle, un groupe aralkyle, ou un groupe aryle, A1 représente un atome d'hydrogène ou un groupe alkyle).
(JA) 本発明は、下記一般式(1)で表されるN,N'-ジアリール尿素誘導体及びその製造方法である。また、本発明は、常温で無色ないし淡色の塩基性染料と、加熱により該塩基性染料と接触して呈色し得る顕色剤とを含有する感熱記録層を支持体上に設けた感熱記録材料であって、前記顕色剤が、下記一般式(1)で表されるN,N'-ジアリール尿素誘導体(式中、R2は、アルキル基、アラルキル基又はアリール基であり、A1は、水素原子、又は、アルキル基を表す。)である。
