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.

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.

Abstract: The present invention relates to aqueous binders and to heat-sealing lacquers produced therefrom for heat-sealable coatings which adhere on aluminium without use of any primer, permit good sealability of the coated aluminium foil with respect to PS and/or PVC, and moreover feature good blocking resistance even at temperatures above 40° C.

Abstract: A polymer mixture includes 10 to 90 wt. % of polymer 1 and 10 to 90 wt. % of polymer 2, the total being 100 wt. %. Polymer 1 is polymerized from (a1) 70-95 wt. % of C1-C12 alkylester of (meth)acrylic acid, and (b1) 5-30% wt. % of C2-C8 alkyl ester of (meth)acrylic acid with a quaternary cationic group in the alkyl group. Polymer 2 is polymerized from (a2) 70-95 wt. % of C1-C12 alkylester of (meth)acrylic acid, and (c2) 5-30 wt. % of C2-C6 hydroxy-alkylester of (meth)acrylic acid. Monomers (a1) and (b1) add up to 98-100 wt. %, and most preferred to 100 wt. %. Monomers (a2) and (c2) add up to 98-100 wt. %, most preferred to 100 wt %.

Abstract: A polymer is polymerized from a monomer mixture containing (a) 70 to 95% by weight of 2-ethylhexyl methacrylate (EHMA) and ethyl methacrylate (EMA) or 2-ethylhexyl methacrylate (EHMA) and methyl methacrylate (MMA), (b) 2.5 to 25% by weight of one or more C2 to C6 hydroxy-alkyl esters of acrylic acid or methacrylic acid, (c) 2.5 to 15% by weight of one or more C2 to C8 alkyl esters of acrylic acid or of methacrylic acid with a quaternary cationic group in the alkyl group. The polymer is useful for preparing a dosage form with a sustained release profile and resistance against the influence of ethanol.

Abstract: The invention concerns specifically emulsion polymers which are intraparticulately crosslinked via a hetero-Diels-Alder (HDA) mechanism. The crosslinked polymers can then be wholly or partly decrosslinked by thermal processing, for example in the form of a composite matrix, via a retro-Diels-Alder or retro-hetero-Diels-Alder reaction and interparticulately recrosslinked on cooling. This makes it possible to prepare long shelf life prepregs for composites. But it is also possible to thus realize other materials that have thermoset properties at use temperature but thermoplastic processing properties at a higher temperature.
