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.

γ- and δ-lactones are valuable flavor and fragrance compounds. Their synthesis depends on the availability of suitable hydroxy fatty acid precursors. Three short unspecific peroxygenases were identified that selectively hydroxylate the C4 and C5 positions of C8–C12 fatty acids to yield after lactonization the corresponding γ- and δ-lactones. A preference for C4 over C5 hydroxylation gave γ-lactones

[Construction]
In a preparation process of a polyhydroxycarboxylic acid comprising carrying out dehydration polycondensation of hydroxycarboxylic acids which contain at least lactic acid in an organic solvent in the presence or in the absence of a catalyst a preparation process of the polyhydroxycarboxylic acid comprising use of a raw material containing ethyllactate of which amount is 0.3 mole % or less to a reduced mole number of the raw material monomer.
[Effect]
A high molecular weight of polyhydroxycarboxylic acid is obtained with ease and with inexpensive industrially by a direct polycondensation of a hydroxycarboxylic acid which contains at least lactic acid.
