发明名称 Method of removing paper adhered to a surface
摘要 Paper adhered to a surface with a starch-based adhesive is removed by mixing together (1) an enzyme composition containing a carbohydrase or a carbohydrase and a pratease, (2) a liquid composition containing (a) an activator for the enzyme composition, (b) a wetting agent and (c) a solvent for reducing the rate of evaporation of water from the paper, and (3) warm water, applying the resultant aqueous composition to the paper and physically removing the wet paper after the enzyme has degraded the adhesive. Prior to mixing, the enzyme composition is in a sealed moisture-proof package and the liquid composition is in another package.
