Use of a mixture of na - carboxymethylcellulose, or - mixture with a further water-soluble polymers, and a redispersible polymer powder as adhesives for plaka compression pressures in the wall of the outer region, which are influenced in the witte

摘要

Use is claimed as adhesive for posters in weather-influenced external sites of a mixture containing (A) a water-soluble polymer (preferably a polysaccharide derivative); and (B) a non-water-soluble but water-dispersible polymer (preferably polyvinyl acetate). Preferably (A) is Na carboxymethylcellulose, Me cellulose, carboxymethyl starch or hydroxypropyl starch. The composition comprises 1-99.5 wt.% (A) and 0.5-99 wt.% (B), an especially preferred composition comprising 80-99 wt.% Na carboxymethylcellulose, 8-12 wt.% redispersion powder and 0.1-1 wt.% preservative.
