• The preferred polymeric hot-melt compositions are those having a melt viscosity between about 500 and 100,000 centipoises at 350 F. Examples of hot-melt compositions usable in this invention are acrylic polymers, such as those formed by polymerizing acrylic monomers such as alkyl acrylates and methacrylates, wherein the alkyl radical of the acrylate preferably contains from about 4 carbon atoms to
