Patent number: 11807025Abstract: 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.Type: GrantFiled: May 25, 2018Date of Patent: November 7, 2023Assignees: Evonik Operations GmbH, Evonik Specialty Chemicals (Shanghai) Co., Ltd.Inventors: Huifeng Yu, Jianmin Yang, Fei Teng, Chenyu Ye, Florian Hermes, Martin Wielpütz

Publication number: 20080217821Abstract: Two shaped articles A and B which are not directly weldable to one another can be welded to one another with the aid of a film C if the material of the first surface of this film is compatible with the material of the shaped article A and the material of the second surface of this film is compatible with the material of the shaped article B and if either the film C or a surface region in contact therewith absorbs electromagnetic radiation. The welding is carried out by brining the first surface of the film C into contact with the shaped article A and the second surface of the film C into contact with the shaped article B and inputting electromagnetic radiation.Type: ApplicationFiled: August 11, 2006Publication date: September 11, 2008Inventors: Rainer Goring, Martin Wielputz, Franz-Erich Baumann, Karl Kuhmann, Sylvia Monsheimer
