  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.
