Title (EN) HEAT-SENSITIVE RECORDING MATERIAL
(FR) MATÉRIAU D'ENREGISTREMENT THERMOSENSIBLE
(JA) 感熱記録材料
Abstract:
(EN) A heat-sensitive recording layer provided on a supporting body contains this heat-sensitive recording material which is mainly composed of a chromogenic compound that is usually colorless or pale-colored, a developer compound that is capable of causing the chromogenic compound to develop a color when heated, and a sensitizer. According to the present invention, the heat-sensitive recording material contains bis(3-allyl-4-hydroxyphenyl)sulfone having α-form crystals and bis(p-allyloxyphenyl)sulfone at a weight ratio of from 7:3 to 6:4.
(FR) L'invention concerne une couche d'enregistrement thermosensible disposée sur un corps de support contenant ledit matériau d'enregistrement thermosensible qui est principalement composé d'un composé chromogène qui est habituellement incolore ou de couleur pâle, un composé de développement qui permet d'amener le composé chromogène à développer une couleur lorsqu'il est chauffé, et un sensibilisateur. Selon la présente invention, le matériau d'enregistrement thermosensible contient du bis (3-allyl-4-hydroxyphényl)sulfone comprenant des cristaux de forme α et du bis(p-allyloxyphényl)sulfone selon un rapport de poids de 7:3 à 6:4.
(JA)  支持体上に設けた感熱記録層は通常無色ないし淡色の発色性化合物、該発色性化合物を熱時発色させうる顕色性化合物及び増感剤を主要成分とする感熱記録材料を含む。本発明においては、α型の結晶を有するビス(3-アリル-4-ヒドロキシフェニル)スルホンとビス(p-アリルオキシフェニル)スルホンとの重量比が7:3~6:4の割合で含まれる感熱記録材料とする。
