Abstract: 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.

A shoe outsole containing the polyamide composition is also useful.

Abstract: In the method for decolorizing a vegetable wax, a vegetable wax raw material dissolved in an organic solvent is contacted under pressure with a nanofiltration membrane having a higher rejection for a pigment, contained in the vegetable wax raw material, than for the wax components, providing a permeate containing decolorized wax and enriching the pigment in the retentate.

Abstract: A polymer based composite contains (a) a polyamide component, (b) a (co)-polyamide based on ether units and amide units, and (c) carbon black. It has been found that (1) the (co)-polyamide (b) offers sufficient absorbency for the printing ink, and (2) the selection of the polyamide component, the (co)-polyamide, and the amount of the carbon black result in both sufficient transparency and sufficient absorption centers for the laser energy. A moulded article can be made of the polymer based composite. A layered structure can be made containing at least one layer made of the polymer based composite and a security and/or valuable document containing the layered structure.

Abstract: A laser markable polymer composite contains (a) a polyamide component as the matrix and (b) carbon black as a laser-sensitive additive. The polyamide component has, based on the total weight thereof, at least 50 wt % a poly amide selected from a linear aliphatic polyamide (a1) or (a2), a cycloaliphatic polyamide (a3), a semi-aromatic polyamide (a4) or (a5), and the compound or copolymer thereof. The carbon black is present in an amount of 50-300 ppm, based on the total weight of the polymer composite. The composite results in better chemical resistance than conventional polycarbonate as the matrix, in addition to a desired quality of laser marking, specifically sharpness and resolution. This composite can also be used for a moulded article made of the laser markable polymer composite, a layered structure with at least one layer made of the laser markable polymer composite, and a security and/or valuable document with the layered structure.
