An improved process can be used for the acid hydrolysis of polylaurolactam with sulfuric acid. An especially suitable starting material is polylaurolactam which is intended for recycling and which is characterized by a low laurolactam content.

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.

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&#xb0; C.

Aqueous binders for heat-sealing applications

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.

The present invention relates to aqueous binders and to heat-sealing lacquers produced therefrom for heat-sealable coatings which adhere on aluminum without use of any primer, permit good sealability of the coated aluminum foil with respect to PS and/or PVC, and moreover feature good blocking resistance even at temperatures above 40&#xb0; C.

The invention relates to a coating composition suitable for the coating of a pharmaceutical or nutraceutical dosage form, comprising a core comprising one or more pharmaceutical or nutraceutical active ingredients, wherein the coating composition is comprising at least 20% by weight of an enteric core/shell polymer composition derived from an emulsion polymerization process, wherein either the core of the core/shell polymer composition is formed by a water-insoluble, not cross-linked polymer or copolymer and the shell of the core/shell polymer composition is formed by an anionic polymer or copolymer or vice versa.

The invention relates to a novel support material for the fused deposition modelling process for producing three-dimensional objects. The invention relates more particularly to a 3D printing process involving support materials which are easier to remove than in the prior art. The support materials according to the invention are styrene-maleic anhydride copolymers for example.
