(FR) FEUILLE DE REPRODUCTION THERMOSENSIBLE
Abstract:
(DE) Bei einem wärmeempfindlichen Aufzeichnungsbogen ist die wärmeempfindliche Aufzeichnungsschicht durch eine pigmenthaltige Schutzschicht abgedeckt, die eine Mischung aus 32 bis 58 Gew.-Teilen eines wasserunlöslichen und 8 bis 16 Gew.-Teilen eines wasserlöslichen Bindemittels enthält, wobei die Schutzschicht 12 bis 20 Gew.-Teile Pigment aufweist und je Gew.-Teil der Bindemittelmischung weniger als 0,5 Gew.-Teile Pigment vorliegen, wobei sich alle Angaben auf das Trockengewicht und auf 100 Gew.-Teile Gesamtgewicht der Schutzschicht beziehen.
(EN) The heat-sensitive recording layer of a heat-sensitive recording sheet is covered by a pigment-containing protective layer containing a mixture of 32-58 parts by weight of a non-water-soluble binder and 8-16 parts by weight of a water-soluble binder. The protective layer contains 12-20 parts by weight pigment, less than 0.5 parts by weight of pigment being present for every part by weight of binder mixture. All figures refer to dry weight and a total of 100 parts by weight of protective layer.
(FR) L'invention concerne une feuille de reproduction thermosensible dont la couche de reproduction thermosensible est recouverte d'une couche protectrice pigmentée qui comprend un mélange de 32 à 58 parties en poids d'un liant insoluble dans l'eau et de 8 à 16 parties en poids d'un liant soluble dans l'eau. La couche protectrice présente 12 à 20 parties en poids de pigments et pour chaque partie en poids du mélange de liants, moins de 0,5 partie en poids de pigments. Toutes les indications se réfèrent au poids sec et au poids total de 100 parties en poids de la couche protectrice.
