Paper is disclosed for use in making repositionable or removable adhesive labels. The adhesive can be applied in patches or discrete areas to the paper or to a layer of material that cleans rollers in the manufacturing line and/or in printers. The adhesive can be applied in single or multiple layers. The paper is light weight paper and preferably thermal paper for use in POS printers.

The present invention relates to transfer media for transferring a functional active ingredient to a surface of an article by means of heat, to methods for preparing such transfer media and for providing of a surface of an article with a functional active ingredient. The transfer media can be used in various technical fields.

In a seal-type thermal transfer image-receiving sheet, the total thickness thereof is 250 μm or less, a seal portion has a layered structure in which a pressure-adhesive layer, a seal portion substrate, and a receiving layer are layered in this order from a release portion side. A release portion has a layered structure in which a surface resin layer, a release portion paper substrate, and a back face resin layer are layered in this order from a seal portion side. One or both of the seal portion substrate and the surface resin layer includes a layer made of polyethylene terephthalate is 50 μm or more. The sum of the thickness of the seal portion substrate and the thickness of the surface resin layer is four times or more the thickness of the back face resin layer, and the thickness of the back face resin layer is 20 μm or more.

A plastic material is useful as an ink receiver or printing medium in dye diffusion thermal transfer printing, wherein the plastic material has a polyamide component (a), and a (co)-polyamide (b) based on ether units and amide units. This plastic material can be used to make a layered structure. The layered structure can be used in dye diffusion thermal transfer printing. A security and/or valuable document with the layered structure can be obtained. Based on the finding that the (co)-polyamide (h) offers sufficient absorbency for the printing ink, the layer produced from the plastic material can be printed on by means of dye diffusion thermal transfer printing with a good color intensity.
