Abstract
(EN)
Provided is a heat transfer sheet in which the transfer layer has both good adherence and good separability. This heat transfer sheet includes a substrate 1, a release layer 2, and a transfer layer 10, which are layered in the order listed. Between the release layer 2 and the transfer layer 10 is a transfer interface of the transfer layer 10, and the release layer 2 contains an acid-modified polyolefin.

L'invention concerne une feuille de transfert thermique dans laquelle la couche de transfert présente à la fois une bonne adhérence et une bonne séparabilité. Cette feuille de transfert thermique comprend un substrat (1), une couche de libération (2), et une couche de transfert (10), qui sont stratifiées dans l'ordre indiqué. Entre la couche de libération (2) et la couche de transfert (10) se trouve une interface de transfert de la couche de transfert (10), et la couche de libération (2) contient une polyoléfine modifiée par un acide.
