Title
(EN) NON-CHEMICAL THERMALLY PRINTABLE FILM
(FR) FILM IMPRIMABLE THERMIQUEMENT NON CHIMIQUE
Abstract
(EN)
A two-layer mono-axially oriented film includes a first layer of an opaque beta-nucleated microvoided propylene-based polymer; and a second layer containing a dark pigment that is adapted for use in a thermal printer in which the thermal print-head contacts the exposed surface of the first layer. The dark pigment of the second layer pigment has a color contrasting with the color of the first layer and can contain a carbon black. The first layer includes microvoids and may be made transparent upon the application of heat by collapsing the voids of the first layer or upon the application of ultra-sonic energy.
(FR)
L'invention concerne un film à double couche orienté mono-axialement qui comprend une première couche d'un polymère opaque bêta-nucléé microporeux à base de propylène ; et une seconde couche contenant un pigment sombre qui est adapté à être utilisé dans une imprimante thermique dans laquelle la tête d'impression thermique entre en contact avec la surface exposée de la première couche. Le pigment sombre du pigment de seconde couche présente une couleur qui contraste avec celle de la première couche et peut contenir un noir de carbone. La première couche comprend des micropores et peut être rendue transparent lors de l'application de chaleur par compression des pores de la première couche ou lors de l'application de l'énergie ultrasonique.
