(FR) FEUILLE RECEPTRICE D'ENCRE POUR ENREGISTREMENT PAR TRANSFERT THERMIQUE
Abstract
(EN)
A receiver element for use in a thermal imaging process, wherein a surface of a pigment-image receiving layer of the receiver element has a roughness, and the surface is brought into contact with a thermally imageable element, wherein the pigment-image receiving layer provided on the receiver element has an average roughness (Ra) of less than about 1 $g(m) and has surface irregularities having a plurality of peaks, at least about 50 of the peaks having a height of at least about 200 nm and a diameter of about 100 pixels over a surface area of about 458 $g(m) by about 602 $g(m). These roughened receiver elements substantially reduce micro-dropouts in thermal imaging processes.

Cette invention concerne un élément récepteur s'utilisant avec un procédé d'imagerie thermique selon lequel une surface de couche pigmentée réceptrice d'image présente une certaine rugosité et est mise en contact avec un élément thermo-reproductible. La couche pigmentée réceptrice d'image de l'élément récepteur présente une rugosité moyenne (Ra) de moins d'un micron environ, avec des irrégularités de surface sous forme d'une pluralité de crêtes qui, pour environ 50 d'entre elles, ont une hauteur d'au moins 200 nm environ et un diamètre de quelque 100 pixels sur une surface d'environ 458 $g(m) par environ 602 $g(m). Ces éléments récepteurs rugueux réduisent sensiblement les desserrements de forme dans les processus d'imagerie thermique.
