    摘要: A pressure-sensitive adhesive composition includes from about 30 weight percent to about 70 weight percent solids in an aqueous medium. The solids include an acrylic polymer having a glass transition temperature of from about -25.degree. C. to about -85.degree. C. and having an acid number of from about 3 to about 30 and from about 0.75 parts by weight to about 5 parts by weight of a humectant per 100 parts polymer.
