Abstract
Abstract The invention provides a solid adhesive composition useful for temporary and repeated fixation of an article on a surface which comprises about 5.0 to about 45 weight percent of an acrylic resin having a glass transition point of -10° C. or below about 0.1 to about 2.0 weight percent of a polyacrylic acid-based thickening agent, about 5.0 to about 30 weight percent of a fatty acid soap, about 0.1 to about 2.0 weight percent of an alkali hydroxide, about 0.1 to about 10 weight percent of microspheres with an average grain size of about 10 to about 200 μm and about 2.0 to about 60 weight percent of water.
