Title (EN) THERMAL IMAGING MEDIUM
(FR) SUPPORT DE FORMATION D'IMAGE THERMIQUE
Abstract:
(EN) There is disclosed a thermal imaging laminar medium, actuatable in response to intense image-forming radiation for production of an image, and including a thermoplastic intermediate layer which, upon separation of the sheet-like or web materials of the laminar medium after thermal exposure, provides surface protection for one of the pair of images obtained thereby.
(FR) L'invention concerne un support multicouche de formation d'image thermique, réagissant à un rayonnement intense de formation d'image, destiné à produire une image et comprenant une couche intermédiaire thermoplastique qui, lors de la séparation de la matière en bande ou en feuille du support multicouche, après l'exposition à la chaleur, constitue une protection de la surface de l'une des deux images ainsi obtenues.
