    The present invention relates to a reusable print medium comprising a substrate and a sacrificial layer. The sacrificial layer contains a hotmelt composition at least comprising an amorphous material. The amorphous material is a resin being a reaction product of a first monomer A, said first monomer A being a polyhydroxyl alcohol comprising X hydroxyl functional groups, wherein X≧2, monomer A optionally comprises a primary or secondary amine functionality; a second monomer B, being an aromatic monocarboxylic acid; a third monomer C, said third monomer C being able to form an ester linkage with an alcohol and/or an amide linkage with a primary or secondary amine; and optionally, a fourth monomer D, being an aromatic monocarboxylic acid different from the second monomer B. The sacrificial layer including the printed image may be removed from the substrate by applying heat. A new sacrificial layer may be applied such that the reusable print medium is ready to be reused. The present invention also relates to a method of manufacturing a reusable print medium according to the present invention, a method of printing and recycling such a print medium and an apparatus for printing and recycling such a print medium.
    本发明涉及一种可重复使用的印刷介质,包括基底和牺牲层。牺牲层含有至少包括非晶态材料的热熔组合物。该非晶态材料是一种树脂,是第一单体A的反应产物,第一单体A是一种聚羟基醇,包括X个羟基官能团,其中X≥2,单体A可选包括一种主链或侧链氨基官能团;第二单体B是一种芳香单羧酸;第三单体C能够与醇形成酯键和/或与一种主链或侧链氨基形成酰胺键;可选地,第四单体D是一种与第二单体B不同的芳香单羧酸。可以通过施加热量从基底中去除包括印刷图像的牺牲层。可以应用新的牺牲层,使可重复使用的印刷介质准备好被重用。本发明还涉及一种制造可重复使用的印刷介质的方法,一种印刷和回收这样的印刷介质的方法,以及一种印刷和回收这样的印刷介质的装置。
