Abstract:
This adhesive composition contains a modified polyolefin resin. The polyolefin resin is obtained by modifying a polyolefin resin with an unsaturated carboxylic acid and a radically reactive aromatic compound. The heat of fusion of the polyolefin resin as determined in accordance with JIS K7122 is 10 J/g or less. The modification amount of the unsaturated carboxylic acid with respect to the modified polyolefin resin is more than 0.5% by mass but less than 5% by mass. The modification amount of the radically reactive aromatic compound with respect to the modified polyolefin resin is not less than 0.1% by mass but less than 3% by mass.
