    摘要: The invention relates to a flat security element for a security paper, value document or the like having a substrate (20) with two opposite main faces. According to the invention, at least one main face of the substrate (20) is provided with a fiber coating (22) to improve the embedding of the security element (12) in a security paper or a value document.

    摘要: The present invention provides a process for the production of a polysaccharide matrix to which haptens are covalently bound, wherein polysaccharide-containing material is rendered alkaline, dried to a water content of less than 5% and then reacted in an anhydrous medium with a hapten containing at least one activated functional group.The present invention also provides a device for carrying out this process, which comprises a winding core (3) in a container (1) for a reaction solution which has a tube (11), provided on its wall with a plurality of openings (7) and closed on one end (9), for the reception of a winding (13) of the material to be treated and two axial end walls (15, 17) for sealing off the axial ends of the winding (13) and feeds the reaction solution from the container (1) into the other end (21) of the tube (11) by means of a circulating pump cycle (19).

    摘要: The invention relates to an optionally foamed sealing composition for preformed seals which can swell when treated with water. The invention also relates to a method for the production thereof out of natural rubber and/or elastomers with a matrix comprised of natural rubber/elastomer components and particle-shaped water absorbing material stored therein. The water absorbing material is a combination of (A) polysaccharide(s) selected from cellulose, starch, starch derivatives removed from grafted starch, amylose, amylopectin, dextran, pectin, inulin, chitin, xanthan, alginic acid, alginates, carrageenan, pustulan, callose, laminarin, guluronic acid, pullulan, lichenin or mixtures of the same with (B) a highly water absorbent synthetic polymer selected from polymers based on (meth)acrylate, poly(meth)acrylic acid and the salts thereof, polyacrylamide, polyalcohols or copolymers of said synthetic polymers. The invention also relates to additional cross-linking and processing auxiliary agents and to property improving agents. It is possible to securely seal superstructures, substructures, tunnels and canals with the assistance of the inventive sealing compositions.
