Abstract
(A1) Die Erfindung betrifft einen Gegenstand mit Klebschicht, der durch Beschichtung eines flaechigen Traegermaterial mit einer Klebstoffzusammensetzung und anschliessende Trocknung erhaeltlich ist. Die verwendete Klebstoffzusammensetzung enthaelt mindestens eine waessrige Polymerdispersion mit einer Glasuebergangstemperatur kleiner 20°C und anorganische Partikel, bevorzugt Nanopartikel. Als flaechiges Traegermaterial sind insbesondere Traegermaterialien wie Papier oder Folien zu nennen.
DE 102007032955 A1 UPAB: 20090313 NOVELTY - Article comprises an adhesive layer, which is obtained by coating a laminar substrate with an adhesive composition, subsequently drying and optionally further treating the coated substrate, where the adhesive composition comprises at least an aqueous polymer dispersion with a glass transition temperature of less than 20 degrees C and inorganic particle with a primary particle size of less than 50 mu m, preferably less than 100 nm, where the polymer dispersions based on chloroprene is excluded. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an adhesive composition comprising at least an aqueous polymer dispersion with a glass transition temperature of less than 20 degrees C and an inorganic particle with a primary particle size of less than 50 mu m, preferably less than 100 nm, where the polymer dispersions based on chloroprene is excluded. USE - The adhesive composition is useful for the coating of articles, so that self adhesive articles are obtained (claimed). ADVANTAGE - The adhesive composition: shows adjustable adhesive strength; bonds the paper and other substrate with high firmness and with permanent alignment and is suitable for sensitive surfaces like e.g. lenses, displays or polished metals and shows elastic transparency. The adhesive layer shows a surface stickiness of 5-20 cm (measured according to DIN EN 1721). The peel strength on the coated printer paper as substrate amounts to maximum 0.06 N/mm, preferably 0.008-0.016 N/mm (according to DIN EN 28510).
