Title (EN) THERMAL TRANSFER SHEET
(FR) FEUILLE DE TRANSFERT THERMIQUE
(JA) 熱転写シート
Abstract:
(EN) Provided is a thermal transfer sheet that can suppress thermal fusion of the thermal transfer sheet and a transfer-receiving body and can improve the durability of a print obtained by transferring a transfer layer onto the transfer-receiving body, even if energy applied to the thermal transfer sheet was increased when transferring the transfer layer onto the transfer-receiving body. This thermal transfer sheet 100 is equipped with a thermal transfer layer 10 on one surface of a substrate 1. The transfer layer 10 is constituted by one or two or more layers, and among the layers constituting the transfer layer 10, the layer closest to the substrate 1 contains a copolymer of isobutyl (meth)acrylate and a monomer having a carboxyl group, and the acid value of said copolymer is 40 mgKOH/g or more.
(FR) L'invention concerne une feuille de transfert thermique qui peut supprimer la fusion thermique entre la feuille de transfert thermique et un corps de réception de transfert et qui peut améliorer la durabilité d'une impression obtenue par le transfert d'une couche de transfert sur le corps de réception de transfert, même si l'énergie appliquée au niveau de la feuille de transfert thermique a été augmentée lors du transfert de la couche de transfert sur le corps de réception de transfert. Cette feuille de transfert thermique 100 est équipée d'une couche de transfert thermique 10 sur une surface d'un substrat 1. La couche de transfert 10 est constituée d'une ou de deux couches ou plus, et parmi les couches constituant la couche de transfert 10, la couche la plus proche du substrat 1 contient un copolymère de méthacrylate d'isobutyle et un monomère ayant un groupe carboxyle, et l'indice d'acide du copolymère est de 40 mgKOH/g ou plus.
(JA) 被転写体上に転写層を転写するときに熱転写シートに印加するエネルギーを高くしていった場合であっても、被転写体と熱転写シートとが熱融着してしまうことを抑制でき、且つ被転写体上に転写層を転写することで得られる印画物の耐久性を向上させることができる熱転写シートを提供すること。 基材1の一方の面上に転写層10が設けられた熱転写シート100であって、転写層10は、1又は2以上の層から構成され、転写層10を構成する層のうち、基材1から最も近くに位置する層が、イソブチル(メタ)アクリレートと、カルボキシル基を有するモノマーとの共重合体を含有しており、当該共重合体の酸価が40mgKOH/g以上である。
