    • 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打印介质,包括基板和牺牲层。 牺牲层含有至少包含无定形材料的热熔组合物。 无定形材料是作为第一单体A的反应产物的树脂,所述第一单体A是包含X羟基官能团的多羟基醇,其中X> = 2,单体A任选地包含伯胺或仲胺官能团; 第二单体B,为芳族单羧酸; 第三单体C,所述第三单体C能够与伯胺或仲胺形成与醇和/或酰胺键的酯键; 和任选的第四单体D,其是与第二单体B不同的芳族单羧酸。包括印刷图像的牺牲层可以通过加热从基材中除去。 可以施加新的牺牲层,使得可重复使用的打印介质准备好重新使用。 本发明还涉及制造根据本发明的可重复使用的打印介质的方法,一种打印和再循环这种打印介质的方法以及用于打印和再循环这种打印介质的设备。
