ABSTRACT:
It has been discovered that certain hot melt adhesive formulations can be produced which exhibit superior lay-flat properties when used as bookbinding adhesives. The formulations incorporate copolymers of ethylene and unsaturated esters. The resulting bookbinding adhesives have viscosities of 2,000 to 8,000 cps at 177.degree. C. The bookbinding adhesives are found to impart lay-flat properties to books when the adhesives have a tensile to elongation ratio of .ltoreq.1.45.
