Abstract

L'invention concerne un milieu de transfert intermédiaire susceptible d'obtenir, dans une région d'un corps cible de transfert vers lequel effectuer le transfert, à la fois une adhérence entre le corps cible de transfert et un patch, et de bonnes caractéristiques de recouvrement au niveau du bord externe du patch. Le support de transfert intermédiaire comprend un élément antiadhésif et une feuille de transfert : la feuille de transfert a un matériau de base de protection et une couche de transfert, dans cet ordre à partir du côté de l'élément antiadhésif ; une fente qui pénètre à travers la feuille de transfert vers l'élément antiadhésif est disposée à partir de la surface de la feuille de transfert sur le côté opposé au côté élément antiadhésif ; une région de la feuille de transfert qui est définie par la fente, en tant que périphérie externe de ladite région, peut être transférée, en tant que patch, vers le corps cible de transfert ; la couche de transfert a au moins une couche de réception et une couche intermédiaire ; la couche de réception contient un copolymère de chlorure de vinyle-acétate de vinyle ; la couche intermédiaire contient une résine (méth)acrylique ; la température de transition vitreuse de la résine (méth)acrylique est égale ou supérieure à 120 °C ; et l'indice d'acide de la résine (méth)acrylique est égal ou supérieur à 15 mgKOH/g.
