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.
