Abstract
It is an object of the present invention to provide a modified polyolefin resin adhesive agent which is excellent in adhesiveness to a nonpolar substrate, particularly a poorly adhesive polyolefin substrate to which no surface treatment has been given and to a polar substrate, develops the excellent adhesiveness by drying or thermal compression bonding at relatively low temperature, and exhibits a low tack. That is, the present invention provides the modified polyolefin resin obtained by modifying a polyolefin resin with (A) a polarity imparting agent which is at least one selected from chlorine, unsaturated carboxylic acid, derivatives and anhydrides of unsaturated carboxylic acid and radical polymerizable monomers; and (B) an ethylene-α-olefin copolymer having an unsaturated bond at one end, and use of said modified polyolefin resin as an aqueous resin composition or an organic solvent resin composition.
