  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。

  THE heart-wood of Western red cedar (Thuja plicata Don.), which possesses a low specific gravity and is very resistant towards decay, has been examined by Anderson and Sherrard1. The steam distillate of this wood furnished an acid, C10H12O2, termed dehydroperillic acid, showing low toxicity, and a very toxic ‘phenol’, m.p. 82°, of the same composition. For dehydroperillic acid they suggest the formula

  Anderson 和 Sherrard1 研究了西部红柏 (Thuja plicata Don.) 的心材，它具有低比重并且非常耐腐烂。这种木材的蒸汽馏出物提供了一种酸，C10H12O2，称为脱氢紫苏酸，显示出低毒性，以及一种毒性很大的“苯酚”，熔点 82°，成分相同。对于脱氢紫苏酸，他们建议式(I)，但没有阐明mp 82°的化合物的结构。

  The present invention relates to a reusable print medium (200) comprising a substrate (201) and a sacrificial layer (202). 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 and a method of printing and recycling such a print medium.

  本发明涉及一种可重复使用的打印介质（200），它包括一个基底（201）和一个牺牲层（202）。牺牲层包含一种热熔胶组合物，至少包括一种非晶材料。无定形材料是一种树脂，是第一单体 A 的反应产物，所述第一单体 A 是一种多羟基醇，包含 X 个羟基官能团，其中 X ≥ 2，单体 A 可选择包含伯胺或仲胺官能团；第二单体 B，为芳香族单羧酸； 第三单体 C，所述第三单体 C 能与醇形成酯连接和/或与伯胺或仲胺形成酰胺连接；以及 第四单体 D，为不同于第二单体 B 的芳香族单羧酸。可通过加热将包括印刷图像的牺牲层从基底上去除。然后再涂上一层新的牺牲层，这样可重复使用的打印介质就可以重复使用了。 本发明还涉及根据本发明制造可重复使用打印介质的方法，以及打印和回收这种打印介质的方法。
