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.
The invention relates to compounds of the formula I,
in which X

, Sp, and R are as defined herein, and to the use thereof in liquid-crystal media, but also to the use of these liquid-crystal media in liquid-crystal displays, and also to liquid-crystal displays of this type per se.
A polymer composition comprises: polymeric material of which at least one third is constituted by homopolymer or copolymer of vinylchloride; five to one hundred in parts per hundred parts of total polymer of a plasticiser selected from the organic esters of formula
in which R1 is selected from the lower (meaning up to C20) alkyl groups; R2 is selected from H, the lower alkyl and lower acyl groups; and R3 and R4 are independently selected from H, OH, loweralkyl groups, and lower acyloxy groups, such group (in every case) optionally having one or more than one substituent selected from lower alkyl groups, lower acyl groups and lower acyloxy groups; and effective amounts of at least one stabiliser and at least one smoke suppressant.
The plasticisers produce a synergistic smoke suppressant effect with most commercially available smoke suppressants.

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。
