摘要: Disclosed is a hot melt adhesive comprising: (A) a metallocene based propylene homopolymer, (B) a metallocene based ethylene/α-olefin copolymer, (C) a tackifier resin, and (D) a plasticizer, wherein the plasticizer (D) comprises (D1) an oil and (D2) at least one polymer selected from polybutene, polybutadiene, polyisobutylene, and polyisoprene. This hot melt adhesive has an initial adhesive strength enough to enable a pressure sensitive adhesion body to stick easily on a member, thus making it possible to firmly hold the pressure sensitive adhesion body on the member. The hot melt adhesive is also excellent in releasability, thus causing no adhesive residue on the member when the pressure sensitive adhesion body is peeled from the member.

摘要: The present invention provides a hot melt adhesive suitable for use in disposable products, which can be applied at a high speed and provides excellent in adhesion in a wet state and low-temperature coating, with little odor. The hot melt adhesive for disposable products comprises: (A) a propylene homopolymer having a melting point of 100° C. or lower obtained by polymerizing propylene using a metallocene catalyst; and (B) a wax modified with carboxylic acid and/or carboxylic acid anhydride. The wet adhesion of the hot melt adhesive is improved when the wax is modified with maleic acid and/or maleic anhydride.
